Bug Fixes
---------
- Fix regression in ``Node.add_marker`` by extracting the mark object of a
``MarkDecorator``. (`3555
<https://github.com/pytest-dev/pytest/issues/3555>`_)
- Warnings without ``location`` were reported as ``None``. This is corrected to
now report ``<undetermined location>``. (`3563
<https://github.com/pytest-dev/pytest/issues/3563>`_)

instead invoke ``pytest`` or ``tox`` directly. (`3552
<https://github.com/pytest-dev/pytest/issues/3552>`_)
- Fix typo in documentation (`3567
<https://github.com/pytest-dev/pytest/issues/3567>`_)
```

<https://github.com/pytest-dev/pytest/issues/3529>`_)
```
### 3.6.0
```
=========================
Features
--------
- Revamp the internals of the ``pytest.mark`` implementation with correct per
node handling which fixes a number of long standing bugs caused by the old
design. This introduces new ``Node.iter_markers(name)`` and
``Node.get_closest_mark(name)`` APIs. Users are **strongly encouraged** to
read the `reasons for the revamp in the docs
<https://docs.pytest.org/en/latest/mark.htmlmarker-revamp-and-iteration>`_,
or jump over to details about `updating existing code to use the new APIs
<https://docs.pytest.org/en/latest/mark.htmlupdating-code>`_. (`3317
<https://github.com/pytest-dev/pytest/issues/3317>`_)
- Now when ``pytest.fixture`` is applied more than once to the same function a
``ValueError`` is raised. This buggy behavior would cause surprising problems
and if was working for a test suite it was mostly by accident. (`2334
<https://github.com/pytest-dev/pytest/issues/2334>`_)
- Support for Python 3.7's builtin ``breakpoint()`` method, see `Using the
builtin breakpoint function
<https://docs.pytest.org/en/latest/usage.htmlbreakpoint-builtin>`_ for
details. (`3180 <https://github.com/pytest-dev/pytest/issues/3180>`_)
- ``monkeypatch`` now supports a ``context()`` function which acts as a context
manager which undoes all patching done within the ``with`` block. (`3290
<https://github.com/pytest-dev/pytest/issues/3290>`_)
- The ``--pdb`` option now causes KeyboardInterrupt to enter the debugger,
instead of stopping the test session. On python 2.7, hitting CTRL+C again
exits the debugger. On python 3.2 and higher, use CTRL+D. (`3299
<https://github.com/pytest-dev/pytest/issues/3299>`_)
- pytest not longer changes the log level of the root logger when the
``log-level`` parameter has greater numeric value than that of the level of
the root logger, which makes it play better with custom logging configuration
in user code. (`3307 <https://github.com/pytest-dev/pytest/issues/3307>`_)
Bug Fixes
---------
- A rare race-condition which might result in corrupted ``.pyc`` files on
Windows has been hopefully solved. (`3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)
- Also use iter_marker for discovering the marks applying for marker
expressions from the cli to avoid the bad data from the legacy mark storage.
(`3441 <https://github.com/pytest-dev/pytest/issues/3441>`_)
- When showing diffs of failed assertions where the contents contain only
whitespace, escape them using ``repr()`` first to make it easy to spot the
differences. (`3443 <https://github.com/pytest-dev/pytest/issues/3443>`_)
Improved Documentation
----------------------
- Change documentation copyright year to a range which auto-updates itself each
time it is published. (`3303
<https://github.com/pytest-dev/pytest/issues/3303>`_)
Trivial/Internal Changes
------------------------
- ``pytest`` now depends on the `python-atomicwrites
<https://github.com/untitaker/python-atomicwrites>`_ library. (`3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)
- Update all pypi.python.org URLs to pypi.org. (`3431
<https://github.com/pytest-dev/pytest/issues/3431>`_)
- Detect `pytest_` prefixed hooks using the internal plugin manager since
``pluggy`` is deprecating the ``implprefix`` argument to ``PluginManager``.
(`3487 <https://github.com/pytest-dev/pytest/issues/3487>`_)
- Import ``Mapping`` and ``Sequence`` from ``_pytest.compat`` instead of
directly from ``collections`` in ``python_api.py::approx``. Add ``Mapping``
to ``_pytest.compat``, import it from ``collections`` on python 2, but from
``collections.abc`` on Python 3 to avoid a ``DeprecationWarning`` on Python
3.7 or newer. (`3497 <https://github.com/pytest-dev/pytest/issues/3497>`_)
```
### 3.5.1
```
=========================
Bug Fixes
---------
- Reset ``sys.last_type``, ``sys.last_value`` and ``sys.last_traceback`` before
each test executes. Those attributes are added by pytest during the test run
to aid debugging, but were never reset so they would create a leaking
reference to the last failing test's frame which in turn could never be
reclaimed by the garbage collector. (`2798
<https://github.com/pytest-dev/pytest/issues/2798>`_)
- ``pytest.raises`` now raises ``TypeError`` when receiving an unknown keyword
argument. (`3348 <https://github.com/pytest-dev/pytest/issues/3348>`_)
- ``pytest.raises`` now works with exception classes that look like iterables.
(`3372 <https://github.com/pytest-dev/pytest/issues/3372>`_)
Improved Documentation
----------------------
- Fix typo in ``caplog`` fixture documentation, which incorrectly identified
certain attributes as methods. (`3406
<https://github.com/pytest-dev/pytest/issues/3406>`_)
Trivial/Internal Changes
------------------------
- Added a more indicative error message when parametrizing a function whose
argument takes a default value. (`3221
<https://github.com/pytest-dev/pytest/issues/3221>`_)
- Remove internal ``_pytest.terminal.flatten`` function in favor of
``more_itertools.collapse``. (`3330
<https://github.com/pytest-dev/pytest/issues/3330>`_)
- Import some modules from ``collections.abc`` instead of ``collections`` as
the former modules trigger ``DeprecationWarning`` in Python 3.7. (`3339
<https://github.com/pytest-dev/pytest/issues/3339>`_)
- record_property is no longer experimental, removing the warnings was
forgotten. (`3360 <https://github.com/pytest-dev/pytest/issues/3360>`_)
- Mention in documentation and CLI help that fixtures with leading ``_`` are
printed by ``pytest --fixtures`` only if the ``-v`` option is added. (`3398
<https://github.com/pytest-dev/pytest/issues/3398>`_)
```
### 3.5.0
```
=========================
Deprecations and Removals
-------------------------
- ``record_xml_property`` fixture is now deprecated in favor of the more
generic ``record_property``. (`2770
<https://github.com/pytest-dev/pytest/issues/2770>`_)
- Defining ``pytest_plugins`` is now deprecated in non-top-level conftest.py
files, because they "leak" to the entire directory tree. (`3084
<https://github.com/pytest-dev/pytest/issues/3084>`_)
Features
--------
- New ``--show-capture`` command-line option that allows to specify how to
display captured output when tests fail: ``no``, ``stdout``, ``stderr``,
``log`` or ``all`` (the default). (`1478
<https://github.com/pytest-dev/pytest/issues/1478>`_)
- New ``--rootdir`` command-line option to override the rules for discovering
the root directory. See `customize
<https://docs.pytest.org/en/latest/customize.html>`_ in the documentation for
details. (`1642 <https://github.com/pytest-dev/pytest/issues/1642>`_)
- Fixtures are now instantiated based on their scopes, with higher-scoped
fixtures (such as ``session``) being instantiated first than lower-scoped
fixtures (such as ``function``). The relative order of fixtures of the same
scope is kept unchanged, based in their declaration order and their
dependencies. (`2405 <https://github.com/pytest-dev/pytest/issues/2405>`_)
- ``record_xml_property`` renamed to ``record_property`` and is now compatible
with xdist, markers and any reporter. ``record_xml_property`` name is now
deprecated. (`2770 <https://github.com/pytest-dev/pytest/issues/2770>`_)
- New ``--nf``, ``--new-first`` options: run new tests first followed by the
rest of the tests, in both cases tests are also sorted by the file modified
time, with more recent files coming first. (`3034
<https://github.com/pytest-dev/pytest/issues/3034>`_)
- New ``--last-failed-no-failures`` command-line option that allows to specify
the behavior of the cache plugin's --last-failed`` feature when no tests
failed in the last run (or no cache was found): ``none`` or ``all`` (the
default). (`3139 <https://github.com/pytest-dev/pytest/issues/3139>`_)
- New ``--doctest-continue-on-failure`` command-line option to enable doctests
to show multiple failures for each snippet, instead of stopping at the first
failure. (`3149 <https://github.com/pytest-dev/pytest/issues/3149>`_)
- Captured log messages are added to the ``<system-out>`` tag in the generated
junit xml file if the ``junit_logging`` ini option is set to ``system-out``.
If the value of this ini option is ``system-err``, the logs are written to
``<system-err>``. The default value for ``junit_logging`` is ``no``, meaning
captured logs are not written to the output file. (`3156
<https://github.com/pytest-dev/pytest/issues/3156>`_)
- Allow the logging plugin to handle ``pytest_runtest_logstart`` and
``pytest_runtest_logfinish`` hooks when live logs are enabled. (`3189
<https://github.com/pytest-dev/pytest/issues/3189>`_)
- Passing ``--log-cli-level`` in the command-line now automatically activates
live logging. (`3190 <https://github.com/pytest-dev/pytest/issues/3190>`_)
- Add command line option ``--deselect`` to allow deselection of individual
tests at collection time. (`3198
<https://github.com/pytest-dev/pytest/issues/3198>`_)
- Captured logs are printed before entering pdb. (`3204
<https://github.com/pytest-dev/pytest/issues/3204>`_)
- Deselected item count is now shown before tests are run, e.g. ``collected X
items / Y deselected``. (`3213
<https://github.com/pytest-dev/pytest/issues/3213>`_)
- The builtin module ``platform`` is now available for use in expressions in
``pytest.mark``. (`3236
<https://github.com/pytest-dev/pytest/issues/3236>`_)
- The *short test summary info* section now is displayed after tracebacks and
warnings in the terminal. (`3255
<https://github.com/pytest-dev/pytest/issues/3255>`_)
- New ``--verbosity`` flag to set verbosity level explicitly. (`3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)
- ``pytest.approx`` now accepts comparing a numpy array with a scalar. (`3312
<https://github.com/pytest-dev/pytest/issues/3312>`_)
Bug Fixes
---------
- Suppress ``IOError`` when closing the temporary file used for capturing
streams in Python 2.7. (`2370
<https://github.com/pytest-dev/pytest/issues/2370>`_)
- Fixed ``clear()`` method on ``caplog`` fixture which cleared ``records``, but
not the ``text`` property. (`3297
<https://github.com/pytest-dev/pytest/issues/3297>`_)
- During test collection, when stdin is not allowed to be read, the
``DontReadFromStdin`` object still allow itself to be iterable and resolved
to an iterator without crashing. (`3314
<https://github.com/pytest-dev/pytest/issues/3314>`_)
Improved Documentation
----------------------
- Added a `reference <https://docs.pytest.org/en/latest/reference.html>`_ page
to the docs. (`1713 <https://github.com/pytest-dev/pytest/issues/1713>`_)
Trivial/Internal Changes
------------------------
- Change minimum requirement of ``attrs`` to ``17.4.0``. (`3228
<https://github.com/pytest-dev/pytest/issues/3228>`_)
- Renamed example directories so all tests pass when ran from the base
directory. (`3245 <https://github.com/pytest-dev/pytest/issues/3245>`_)
- Internal ``mark.py`` module has been turned into a package. (`3250
<https://github.com/pytest-dev/pytest/issues/3250>`_)
- ``pytest`` now depends on the `more-itertools
<https://github.com/erikrose/more-itertools>`_ package. (`3265
<https://github.com/pytest-dev/pytest/issues/3265>`_)
- Added warning when ``[pytest]`` section is used in a ``.cfg`` file passed
with ``-c`` (`3268 <https://github.com/pytest-dev/pytest/issues/3268>`_)
- ``nodeids`` can now be passed explicitly to ``FSCollector`` and ``Node``
constructors. (`3291 <https://github.com/pytest-dev/pytest/issues/3291>`_)
- Internal refactoring of ``FormattedExcinfo`` to use ``attrs`` facilities and
remove old support code for legacy Python versions. (`3292
<https://github.com/pytest-dev/pytest/issues/3292>`_)
- Refactoring to unify how verbosity is handled internally. (`3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)
- Internal refactoring to better integrate with argparse. (`3304
<https://github.com/pytest-dev/pytest/issues/3304>`_)
- Fix a python example when calling a fixture in doc/en/usage.rst (`3308
<https://github.com/pytest-dev/pytest/issues/3308>`_)
```
### 3.4.2
```
=========================
Bug Fixes
---------
- Removed progress information when capture option is ``no``. (`3203
<https://github.com/pytest-dev/pytest/issues/3203>`_)
- Refactor check of bindir from ``exists`` to ``isdir``. (`3241
<https://github.com/pytest-dev/pytest/issues/3241>`_)
- Fix ``TypeError`` issue when using ``approx`` with a ``Decimal`` value.
(`3247 <https://github.com/pytest-dev/pytest/issues/3247>`_)
- Fix reference cycle generated when using the ``request`` fixture. (`3249
<https://github.com/pytest-dev/pytest/issues/3249>`_)
- ``[tool:pytest]`` sections in ``*.cfg`` files passed by the ``-c`` option are
now properly recognized. (`3260
<https://github.com/pytest-dev/pytest/issues/3260>`_)
Improved Documentation
----------------------
- Add logging plugin to plugins list. (`3209
<https://github.com/pytest-dev/pytest/issues/3209>`_)
Trivial/Internal Changes
------------------------
- Fix minor typo in fixture.rst (`3259
<https://github.com/pytest-dev/pytest/issues/3259>`_)
```
### 3.4.1
```
=========================
Bug Fixes
---------
- Move import of ``doctest.UnexpectedException`` to top-level to avoid possible
errors when using ``--pdb``. (`1810
<https://github.com/pytest-dev/pytest/issues/1810>`_)
- Added printing of captured stdout/stderr before entering pdb, and improved a
test which was giving false negatives about output capturing. (`3052
<https://github.com/pytest-dev/pytest/issues/3052>`_)
- Fix ordering of tests using parametrized fixtures which can lead to fixtures
being created more than necessary. (`3161
<https://github.com/pytest-dev/pytest/issues/3161>`_)
- Fix bug where logging happening at hooks outside of "test run" hooks would
cause an internal error. (`3184
<https://github.com/pytest-dev/pytest/issues/3184>`_)
- Detect arguments injected by ``unittest.mock.patch`` decorator correctly when
pypi ``mock.patch`` is installed and imported. (`3206
<https://github.com/pytest-dev/pytest/issues/3206>`_)
- Errors shown when a ``pytest.raises()`` with ``match=`` fails are now cleaner
on what happened: When no exception was raised, the "matching '...'" part got
removed as it falsely implies that an exception was raised but it didn't
match. When a wrong exception was raised, it's now thrown (like
``pytest.raised()`` without ``match=`` would) instead of complaining about
the unmatched text. (`3222
<https://github.com/pytest-dev/pytest/issues/3222>`_)
- Fixed output capture handling in doctests on macOS. (`985
<https://github.com/pytest-dev/pytest/issues/985>`_)
Improved Documentation
----------------------
- Add Sphinx parameter docs for ``match`` and ``message`` args to
``pytest.raises``. (`3202
<https://github.com/pytest-dev/pytest/issues/3202>`_)
Trivial/Internal Changes
------------------------
- pytest has changed the publication procedure and is now being published to
PyPI directly from Travis. (`3060
<https://github.com/pytest-dev/pytest/issues/3060>`_)
- Rename ``ParameterSet._for_parameterize()`` to ``_for_parametrize()`` in
order to comply with the naming convention. (`3166
<https://github.com/pytest-dev/pytest/issues/3166>`_)
- Skip failing pdb/doctest test on mac. (`985
<https://github.com/pytest-dev/pytest/issues/985>`_)

### 1.22.5
```
================================
Bug Fixes
---------
- `321 <https://github.com/pytest-dev/pytest-xdist/issues/321>`_: Revert change that dropped support for ``pytest<3.4`` and require ``six``.
This change caused problems in some installations, and was a mistaken
in the first place as we should not change version requirements
in bug-fix releases unless they fix an actual bug.
```
### 1.22.4
```
================================
Bug Fixes
---------
- `305 <https://github.com/pytest-dev/pytest-xdist/issues/305>`_: Remove last references to obsolete ``py.code``.
Remove some unnecessary references to ``py.builtin``.
- `316 <https://github.com/pytest-dev/pytest-xdist/issues/316>`_: Workaround cpu detection on Travis CI.
```
### 1.22.3
```
================================
Bug Fixes
---------
- Fix issue of virtualized or containerized environments not reporting the number of CPUs correctly. (`9 <https://github.com/pytest-dev/pytest-xdist/issues/9>`_)
Trivial Changes
---------------
- Make all classes subclass from ``object`` and fix ``super()`` call in ``LoadFileScheduling``; (`297 <https://github.com/pytest-dev/pytest-xdist/issues/297>`_)
```
### 1.22.2
```
================================
Bug Fixes
---------
- Add backward compatibility for ``slaveoutput`` attribute to
``WorkerController`` instances. (`285
<https://github.com/pytest-dev/pytest-xdist/issues/285>`_)
```
### 1.22.1
```
================================
Bug Fixes
---------
- Fix issue when using ``loadscope`` or ``loadfile`` where tests would fail to
start if the first scope had only one test. (`257
<https://github.com/pytest-dev/pytest-xdist/issues/257>`_)
Trivial Changes
---------------
- Change terminology used by ``pytest-xdist`` to *master* and *worker* in
arguments and messages (for example ``--max-worker-reset``). (`234
<https://github.com/pytest-dev/pytest-xdist/issues/234>`_)

Changelog
### 1.15.0
```
==========================
Highlights
==========
* NumPy has switched to pytest for testing.
New functions
=============
* `np.gcd` and `np.lcm`, to compute the greatest common divisor and least
common multiple.
* `np.ma.stack`, the `np.stack` array-joining function generalized to masked
arrays.
* ``quantile`` function, an interface to ``percentile`` without factors of 100
* ``nanquantile`` function, an interface to ``nanpercentile`` without factors
of 100
* `np.printoptions`, a context manager that sets print options temporarily
for the scope of the ``with`` block::
>>> with np.printoptions(precision=2):
... print(np.array([2.0]) / 3)
[0.67]
* `np.histogram_bin_edges`, a function to get the edges of the bins used by a histogram
without needing to calculate the histogram.
* `npy_get_floatstatus_barrier`` and ``npy_clear_floatstatus_barrier`` have been added to
deal with compiler optimization changing the order of operations. See below for details.
Deprecations
============
* Aliases of builtin `pickle` functions are deprecated, in favor of their
unaliased ``pickle.<func>`` names:
* `np.loads`
* `np.core.numeric.load`
* `np.core.numeric.loads`
* `np.ma.loads`, `np.ma.dumps`
* `np.ma.load`, `np.ma.dump` - these functions already failed on python 3,
when called with a string.
* Multidimensional indexing with anything but a tuple is
deprecated. This means that code such as ``ind = [slice(None), 0]``,
``arr[[slice(None), 0]]`` should be changed to ``arr[tuple(ind)]``. This is
necessary to avoid ambiguity in expressions such as ``arr[[[0, 1], [0, 1]]]``
which currently is interpreted as ``arr[array([0, 1]), array([0, 1])]``.
In future, this will be interpreted as ``arr[array([[0, 1], [0, 1]])]``.
* Direct imports from the following modules is deprecated. All testing related
imports should come from `numpy.testing`.
* `np.testing.utils`
* `np.testing.decorators`
* `np.testing.nosetester`
* `np.testing.noseclasses`
* `np.core.umath_tests`
* Giving a generator to `np.sum` is now deprecated. This was undocumented, but
worked. Previously, it would calculate the sum of the generator expression.
In the future, it might return a different result. Use `np.sum(np.from_iter(generator))`
or the built-in Python `sum` instead.
* Users of the C-API should call ``PyArrayResolveWriteBackIfCopy`` or
``PyArray_DiscardWritbackIfCopy`` on any array with the ``WRITEBACKIFCOPY``
flag set, before the array is deallocated. A deprecation warning will be
emitted if those calls are not used when needed.
* Users of ``nditer`` should use the nditer object as a context manager
anytime one of the iterator operands is writeable, so that numpy can
manage writeback semantics, or should call ``it.close()``. A
`RuntimeWarning` may be emitted otherwise in these cases.
* The ``normed`` argument of ``np.histogram``, deprecated long ago in 1.6.0,
now emits a ``DeprecationWarning``.
Future Changes
==============
Compatibility notes
===================
The ``NpzFile`` returned by ``np.savez`` is now a `collections.abc.Mapping`
---------------------------------------------------------------------------
This means it behaves like a readonly dictionary, and has a new ``.values()``
method and ``len()`` implementation.
On python 3, this means that ``.iteritems()``, ``.iterkeys()`` have been
deprecated, and ``.keys()`` and ``.items()`` now return views and not lists.
This is consistent with how the builtin ``dict`` type changed between python 2
and python 3.
Under certain conditions, nditer must be used in a context manager
------------------------------------------------------------------
When using an nditer with the ``"writeonly"`` or ``"readwrite"`` flags, there
are some circumstances where nditer doesn't actually give you a view onto the
writable array. Instead, it gives you a copy, and if you make changes to the
copy, nditer later writes those changes back into your actual array. Currently,
this writeback occurs when the array objects are garbage collected, which makes
this API error-prone on CPython and entirely broken on PyPy. Therefore,
``nditer`` should now be used as a context manager whenever using ``nditer``
with writeable arrays (``with np.nditer(...) as it: ...``). You may also
explicitly call ``it.close()`` for cases where a context manager is unusable,
for instance in generator expressions.
Numpy has switched to using pytest instead of nose for testing
--------------------------------------------------------------
The last nose release was 1.3.7 in June, 2015, and development of that tool has
ended, consequently NumPy has now switched to using pytest. The old decorators
and nose tools that were previously used by some downstream projects remain
available, but will not be maintained. The standard testing utilities,
`assert_almost_equal` and such, are not be affected by this change except for
the nose specific functions `import_nose` and `raises`. Those functions are
not used in numpy, but are kept for downstream compatibility.
Numpy no longer monkey-patches ``ctypes`` with ``__array_interface__``
----------------------------------------------------------------------
Previously numpy added ``__array_interface__`` attributes to all the integer
types from ``ctypes``.
``np.ma.notmasked_contiguous`` and ``np.ma.flatnotmasked_contiguous`` always return lists
-----------------------------------------------------------------------------------------
This was always the documented behavior, but in reality the result used to be
any of slice, None, or list.
All downstream users seem to use detect the `None` result from
``flatnotmasked_contiguous`` and replace it with ``[]``.
These callers will continue to work as before.
``np.squeeze`` now respects the API expectation of objects that do not handle an ``axis`` argument
--------------------------------------------------------------------------------------------------
Prior to version ``1.7.0`` ``np.squeeze`` did not have an ``axis`` argument and all empty axes were removed
by default. After incorporation of an ``axis`` argument, it was possible to selectively squeeze single
or multiple empty axes, but the old API expectation was not respected because the axes could still be
selectively removed (silent success) in an object depending on the old API. The silent success is no
longer possible, and objects expecting the old API are respected. The silent success was prevented
by removing the interception of an otherwise-normal Exception when ``axis`` was provided to an object
using the old API.
unstructured void array's ``.item`` method now returns a bytes object
---------------------------------------------------------------------
``.item`` now returns a ``bytes`` object instead of a buffer or byte array.
This may affect code which assumed the return value was mutable, which is no
longer the case.
``copy.copy`` and ``copy.deepcopy`` no longer turn ``masked`` into an array
----------------------------------------------------------------------------
Since ``np.ma.masked`` is a readonly scalar, copying should be a no-op. These
functions now behave consistently with ``np.copy()``.
Multifield Indexing of Structured Arrays will still return a copy
-----------------------------------------------------------------
The change that multi-field indexing of structured arrays returns a view
instead of a copy is pushed back to 1.16. A new method
``numpy.lib.recfunctions.repack_fields`` has been introduced to help mitigate
the effects of this change, which can be used to write code compatible with
both numpy 1.15 and 1.16. For more information on how to update code to account
for this future change see "basics/structured arrays/accessing multiple fields"
in the user guide.
C API changes
=============
* Functions ``npy_get_floatstatus_barrier`` and ``npy_clear_floatstatus_barrier``
have been added and should be used in place of the ``npy_get_floatstatus``and
``npy_clear_status`` functions. Optimizing compilers like GCC 8.1 and Clang
were rearranging the order of operations when the previous functions were
used in the ufunc SIMD functions, resulting in the floatstatus flags being '
checked before the operation whose status we wanted to check was run.
See `10339 <https://github.com/numpy/numpy/issues/10370>`__.
* ``PyArray_GetDTypeTransferFunction`` now defaults to using user-defined
``copyswapn`` / ``copyswap`` for user-defined dtypes. If this causes a
significant performance hit, consider implementing ``copyswapn`` to reflect
the implementation of ``PyArray_GetStridedCopyFn``.
See `10898 <https://github.com/numpy/numpy/pull/10898>`__.
New Features
============
``np.gcd`` and ``np.lcm`` ufuncs added for integer and objects types
--------------------------------------------------------------------
These compute the greatest common divisor, and lowest common multiple,
respectively. These work on all the numpy integer types, as well as the
builtin arbitrary-precision `Decimal` and `long` types.
Support for cross-platform builds for iOS
-----------------------------------------
The build system has been modified to add support for the
``_PYTHON_HOST_PLATFORM`` environment variable, used by ``distutils`` when
compiling on one platform for another platform. This makes it possible to
compile NumPy for iOS targets.
This only enables you to compile NumPy for one specific platform at a time.
Creating a full iOS-compatible NumPy package requires building for the 5
architectures supported by iOS (i386, x86_64, armv7, armv7s and arm64), and
combining these 5 compiled builds products into a single "fat" binary.
``return_indices`` keyword added for ``np.intersect1d``
-------------------------------------------------------
New keyword ``return_indices`` returns the indices of the two input arrays
that correspond to the common elements.
``np.quantile`` and ``np.nanquantile``
--------------------------------------
Like ``np.percentile`` and ``np.nanpercentile``, but takes quantiles in [0, 1]
rather than percentiles in [0, 100]. ``np.percentile`` is now a thin wrapper
around ``np.quantile`` with the extra step of dividing by 100.
Build system
------------
Added experimental support for the 64-bit RISC-V architecture.
Improvements
============
``np.ufunc.reduce`` and related functions now accept an initial value
---------------------------------------------------------------------
``np.ufunc.reduce``, ``np.sum``, ``np.prod``, ``np.min`` and ``np.max`` all
now accept an ``initial`` keyword argument that specifies the value to start
the reduction with.
``np.flip`` can operate over multiple axes
------------------------------------------
``np.flip`` now accepts None, or tuples of int, in its ``axis`` argument. If
axis is None, it will flip over all the axes.
``histogram`` and ``histogramdd`` functions have moved to ``np.lib.histograms``
------------------------------------------------------------------------------
These were originally found in ``np.lib.function_base``. They are still
available under their un-scoped ``np.histogram(dd)`` names, and
to maintain compatibility, aliased at ``np.lib.function_base.histogram(dd)``.
Code that does ``from np.lib.function_base import *`` will need to be updated
with the new location, and should consider not using ``import *`` in future.
``histogram`` will accept NaN values when explicit bins are given
-----------------------------------------------------------------
Previously it would fail when trying to compute a finite range for the data.
Since the range is ignored anyway when the bins are given explicitly, this error
was needless.
Note that calling `histogram` on NaN values continues to raise the
`RuntimeWarning`s typical of working with nan values, which can be silenced
as usual with `errstate`.
``histogram`` works on datetime types, when explicit bin edges are given
------------------------------------------------------------------------
Dates, times, and timedeltas can now be histogrammed. The bin edges must be
passed explicitly, and are not yet computed automatically.
``histogram`` "auto" estimator handles limited variance better
------------------------------------------------------------------------
No longer does an IQR of 0 result in `n_bins=1`, rather the number of bins
chosen is related to the data size in this situation.
``histogram`` and ``histogramdd`` return edges matching the float type of the data
----------------------------------------------------------------------------------
When passed ``float16``, ``np.float32``, or ``np.longdouble`` data, the
returned edges are now of the same dtype. Previously, ``histogram`` would only
return the same type if explicit bins were given, and ``histogram`` would
produce ``float64`` bins no matter what the inputs.
``histogramdd`` allows explicit ranges to be given in a subset of axes
----------------------------------------------------------------------
The ``range`` argument of `histogramdd` can now contain ``None`` values to
indicate that the range for the corresponding axis should be computed from the
data. Previously, this could not be specified on a per-axis basis.
The normed arguments of ``histogramdd`` and ``histogram2d`` have been renamed
-----------------------------------------------------------------------------
These arguments are now called ``density``, which is consistent with
``histogram``. The old argument continues to work, but the new name should be
preferred.
``np.r_`` works with 0d arrays, and ``np.ma.mr_`` works with ``np.ma.masked``
----------------------------------------------------------------------------
0d arrays passed to the `r_` and `mr_` concatenation helpers are now treated as
though they are arrays of length 1. Previously, passing these was an error.
As a result, ``np.ma.mr_`` now works correctly on the ``masked`` constant.
``np.ptp`` accepts a ``keepdims`` argument, and extended axis tuples
--------------------------------------------------------------------
``np.ptp`` (peak-to-peak) can now work over multiple axes, just like `max` and
`min`.
``MaskedArray.astype`` now is identical to ``ndarray.astype``
-------------------------------------------------------------
This means it takes all the same arguments, making more code written for
ndarray work for masked array too.
Enable AVX2/AVX512 at compile time
-------------------------------------------------------------
Change to simd.inc.src to use AVX2 or AVX512 at compile time. Solving the gap
that if compile numpy for avx2 (or 512) with -march=native, still get the SSE
code for the simd functions even though rest of the code gets AVX2.
``nan_to_num`` always returns scalars when receiving scalar or 0d inputs
------------------------------------------------------------------------
Previously an array was returned for integer scalar inputs, which is
inconsistent with the behavior for float inputs, and that of ufuncs in general.
For all types of scalar or 0d input, the result is now a scalar.
``np.flatnonzero`` works on numpy-convertible types
---------------------------------------------------
``np.flatnonzero`` now uses ``np.ravel(a)`` instead of ``a.ravel()``, so it
works for lists, tuples, etc.
``np.interp`` returns numpy scalars rather than builtin scalars
---------------------------------------------------------------
Previously ``np.interp(0.5, [0, 1], [10, 20])`` would return a ``float``, but
now it returns a ``np.float64`` object, which more closely matches the behavior
of other functions.
Additionally, the special case of ``np.interp(object_array_0d, ...)`` is no
longer supported, as ``np.interp(object_array_nd)`` was never supported anyway.
As a result of this change, the ``period`` argument can now be used on 0d
arrays.
Allow dtype field names to be unicode in Python 2
---------------------------------------------------------------
Previously ``np.dtype([(u'name', float)])`` would raise a ``TypeError`` in
Python 2, as only bytestrings were allowed in field names. Now any unicode
string field names will be encoded with the ``ascii`` codec, raising a
``UnicodeEncodeError`` upon failure.
This change makes it easier to write Python 2/3 compatible code using
``from __future__ import unicode_literals``, which previously would cause
string literal field names to raise a TypeError in Python 2.
Comparison ufuncs accept ``dtype=object``, overriding the default ``bool``
--------------------------------------------------------------------------
This allows object arrays of symbolic types, which override ``==`` and other
operators to return expressions, to be compared elementwise with
``np.equal(a, b, dtype=object)``.
``sort`` functions accept ``kind='stable'``
-------------------------------------------
Up until now, to perform a stable sort on the data, the user must do:
>>> np.sort([5, 2, 6, 2, 1], kind='mergesort')
[1, 2, 2, 5, 6]
because merge sort is the only stable sorting algorithm available in
NumPy. However, having kind='mergesort' does not make it explicit that
the user wants to perform a stable sort thus harming the readability.
This change allows the user to specify kind='stable' thus clarifying
the intent.
Do not make temporary copies for in-place accumulation
------------------------------------------------------
When ufuncs perform accumulation they no longer make temporary copies because
of the overlap between input an output, that is, the next element accumulated
is added before the accumulated result is stored in its place, hence the
overlap is safe. Avoiding the copy results in faster execution.
``linalg.matrix_power`` can now handle stacks of matrices
---------------------------------------------------------
Like other functions in ``linalg``, ``matrix_power`` can now deal with arrays
of dimension larger than 2, which are treated as stacks of matrices. As part
of the change, to further improve consistency, the name of the first argument
has been changed to ``a`` (from ``M``), and the exceptions for non-square
matrices have been changed to ``LinAlgError`` (from ``ValueError``).
Increased performance in ``random.permutation`` for multidimensional arrays
---------------------------------------------------------------------------
``permutation`` uses the fast path in ``random.shuffle`` for all input
array dimensions. Previously the fast path was only used for 1-d arrays.
Generalized ufuncs now accept ``axes``, ``axis`` and ``keepdims`` arguments
---------------------------------------------------------------------------
One can control over which axes a generalized ufunc operates by passing in an
``axes`` argument, a list of tuples with indices of particular axes. For
instance, for a signature of ``(i,j),(j,k)->(i,k)`` appropriate for matrix
multiplication, the base elements are two-dimensional matrices and these are
taken to be stored in the two last axes of each argument. The corresponding
axes keyword would be ``[(-2, -1), (-2, -1), (-2, -1)]``. If one wanted to
use leading dimensions instead, one would pass in ``[(0, 1), (0, 1), (0, 1)]``.
For simplicity, for generalized ufuncs that operate on 1-dimensional arrays
(vectors), a single integer is accepted instead of a single-element tuple, and
for generalized ufuncs for which all outputs are scalars, the (empty) output
tuples can be omitted. Hence, for a signature of ``(i),(i)->()`` appropriate
for an inner product, one could pass in ``axes=[0, 0]`` to indicate that the
vectors are stored in the first dimensions of the two inputs arguments.
As a short-cut for generalized ufuncs that are similar to reductions, i.e.,
that act on a single, shared core dimension such as the inner product example
above, one can pass an ``axis`` argument. This is equivalent to passing in
``axes`` with identical entries for all arguments with that core dimension
(e.g., for the example above, ``axes=[(axis,), (axis,)]``).
Furthermore, like for reductions, for generalized ufuncs that have inputs that
all have the same number of core dimensions and outputs with no core dimension,
one can pass in ``keepdims`` to leave a dimension with size 1 in the outputs,
thus allowing proper broadcasting against the original inputs. The location of
the extra dimension can be controlled with ``axes``. For instance, for the
inner-product example, ``keepdims=True, axes=[-2, -2, -2]`` would act on the
inner-product example, ``keepdims=True, axis=-2`` would act on the
one-but-last dimension of the input arguments, and leave a size 1 dimension in
that place in the output.
float128 values now print correctly on ppc systems
--------------------------------------------------
Previously printing float128 values was buggy on ppc, since the special
double-double floating-point-format on these systems was not accounted for.
float128s now print with correct rounding and uniqueness.
Warning to ppc users: You should upgrade glibc if it is version <=2.23,
especially if using float128. On ppc, glibc's malloc in these version often
misaligns allocated memory which can crash numpy when using float128 values.
New ``np.take_along_axis`` and ``np.put_along_axis`` functions
--------------------------------------------------------------
When used on multidimensional arrays, ``argsort``, ``argmin``, ``argmax``, and
``argpartition`` return arrays that are difficult to use as indices.
``take_along_axis`` provides an easy way to use these indices to lookup values
within an array, so that::
np.take_along_axis(a, np.argsort(a, axis=axis), axis=axis)
is the same as::
np.sort(a, axis=axis)
``np.put_along_axis`` acts as the dual operation for writing to these indices
within an array.
.. note:: Implementations of ``__array_ufunc__`` should ensure that they can
handle either ``axis`` or ``axes``. In future, we may convert
``axis`` to ``axes`` before passing it on.
Changes

==========================
```
### 1.14.5
```
==========================
This is a bugfix release for bugs reported following the 1.14.4 release. The
most significant fixes are:
* fixes for compilation errors on alpine and NetBSD
The Python versions supported in this release are 2.7 and 3.4 - 3.6. The Python
3.6 wheels available from PIP are built with Python 3.6.2 and should be
compatible with all previous versions of Python 3.6. The source releases were
cythonized with Cython 0.28.2 and should work for the upcoming Python 3.7.

=========================
```
### 1.14.4
```
==========================
This is a bugfix release for bugs reported following the 1.14.3 release. The
most significant fixes are:
* fixes for compiler instruction reordering that resulted in NaN's not being
properly propagated in `np.max` and `np.min`,
* fixes for bus faults on SPARC and older ARM due to incorrect alignment
checks.
There are also improvements to printing of long doubles on PPC platforms. All
is not yet perfect on that platform, the whitespace padding is still incorrect
and is to be fixed in numpy 1.15, consequently NumPy still fails some
printing-related (and other) unit tests on ppc systems. However, the printed
values are now correct.
Note that NumPy will error on import if it detects incorrect float32 `dot`
results. This problem has been seen on the Mac when working in the Anaconda
enviroment and is due to a subtle interaction between MKL and PyQt5. It is not
strictly a NumPy problem, but it is best that users be aware of it. See the
gh-8577 NumPy issue for more information.
The Python versions supported in this release are 2.7 and 3.4 - 3.6. The Python
3.6 wheels available from PIP are built with Python 3.6.2 and should be
compatible with all previous versions of Python 3.6. The source releases were
cythonized with Cython 0.28.2 and should work for the upcoming Python 3.7.

### 1.14.1
```
==========================
This is a bugfix release for some problems reported following the 1.14.0 release. The major
problems fixed are the following.
* Problems with the new array printing, particularly the printing of complex
values, Please report any additional problems that may turn up.
* Problems with ``np.einsum`` due to the new ``optimized=True`` default. Some
fixes for optimization have been applied and ``optimize=False`` is now the
default.
* The sort order in ``np.unique`` when ``axis=<some-number>`` will now always
be lexicographic in the subarray elements. In previous NumPy versions there
was an optimization that could result in sorting the subarrays as unsigned
byte strings.
* The change in 1.14.0 that multi-field indexing of structured arrays returns a
view instead of a copy has been reverted but remains on track for NumPy 1.15.
Affected users should read the 1.14.1 Numpy User Guide section
"basics/structured arrays/accessing multiple fields" for advice on how to
manage this transition.
The Python versions supported in this release are 2.7 and 3.4 - 3.6. The Python

Changelog
### 3.6.4 ``` ========================= Bug Fixes --------- - Invoke pytest using ``-mpytest`` so ``sys.path`` does not get polluted by packages installed in ``site-packages``. (`742 <https://github.com/pytest-dev/pytest/issues/742>`_) Improved Documentation ---------------------- - Use ``smtp_connection`` instead of ``smtp`` in fixtures documentation to avoid possible confusion. (`3592 <https://github.com/pytest-dev/pytest/issues/3592>`_) Trivial/Internal Changes ------------------------ - Remove obsolete ``__future__`` imports. (`2319 <https://github.com/pytest-dev/pytest/issues/2319>`_) - Add CITATION to provide information on how to formally cite pytest.

(`3727 <https://github.com/pytest-dev/pytest/issues/3727>`_) ``` ### 3.6.3 ``` ========================= Bug Fixes --------- - Fix ``ImportWarning`` triggered by explicit relative imports in assertion-rewritten package modules. (`3061 <https://github.com/pytest-dev/pytest/issues/3061>`_) - Fix error in ``pytest.approx`` when dealing with 0-dimension numpy arrays. (`3593 <https://github.com/pytest-dev/pytest/issues/3593>`_) - No longer raise ``ValueError`` when using the ``get_marker`` API. (`3605 <https://github.com/pytest-dev/pytest/issues/3605>`_) - Fix problem where log messages with non-ascii characters would not appear in the output log file. (`3630 <https://github.com/pytest-dev/pytest/issues/3630>`_) - No longer raise ``AttributeError`` when legacy marks can't be stored in functions. (`3631 <https://github.com/pytest-dev/pytest/issues/3631>`_) Improved Documentation ---------------------- - The description above the example for ``pytest.mark.skipif`` now better matches the code. (`3611 <https://github.com/pytest-dev/pytest/issues/3611>`_) Trivial/Internal Changes ------------------------ - Internal refactoring: removed unused ``CallSpec2tox ._globalid_args`` attribute and ``metafunc`` parameter from ``CallSpec2.copy()``. (`3598 <https://github.com/pytest-dev/pytest/issues/3598>`_) - Silence usage of ``reduce`` warning in Python 2 (`3609 <https://github.com/pytest-dev/pytest/issues/3609>`_) - Fix usage of ``attr.ib`` deprecated ``convert`` parameter. (`3653 <https://github.com/pytest-dev/pytest/issues/3653>`_) ``` ### 3.6.2 ``` ========================= Bug Fixes --------- - Fix regression in ``Node.add_marker`` by extracting the mark object of a ``MarkDecorator``. (`3555 <https://github.com/pytest-dev/pytest/issues/3555>`_) - Warnings without ``location`` were reported as ``None``. This is corrected to now report ``<undetermined location>``. (`3563 <https://github.com/pytest-dev/pytest/issues/3563>`_) - Continue to call finalizers in the stack when a finalizer in a former scope raises an exception. (`3569 <https://github.com/pytest-dev/pytest/issues/3569>`_) - Fix encoding error with ``print`` statements in doctests (`3583 <https://github.com/pytest-dev/pytest/issues/3583>`_) Improved Documentation ---------------------- - Add documentation for the ``--strict`` flag.

(`3491 <https://github.com/pytest-dev/pytest/issues/3491>`_) - Fix ``usefixtures`` mark applyed to unittest tests by correctly instantiating ``FixtureInfo``. (`3498 <https://github.com/pytest-dev/pytest/issues/3498>`_) - Fix assertion rewriter compatibility with libraries that monkey patch ``file`` objects. (`3503 <https://github.com/pytest-dev/pytest/issues/3503>`_) Improved Documentation ---------------------- - Added a section on how to use fixtures as factories to the fixture documentation. (`3461 <https://github.com/pytest-dev/pytest/issues/3461>`_) Trivial/Internal Changes ------------------------ - Enable caching for pip/pre-commit in order to reduce build time on travis/appveyor. (`3502 <https://github.com/pytest-dev/pytest/issues/3502>`_) - Switch pytest to the src/ layout as we already suggested it for good practice - now we implement it as well. (`3513 <https://github.com/pytest-dev/pytest/issues/3513>`_) - Fix if in tests to support 3.7.0b5, where a docstring handling in AST got reverted. (`3530 <https://github.com/pytest-dev/pytest/issues/3530>`_) - Remove some python2.5 compatibility code. (`3529 <https://github.com/pytest-dev/pytest/issues/3529>`_) ``` ### 3.6.0 ``` ========================= Features -------- - Revamp the internals of the ``pytest.mark`` implementation with correct per node handling which fixes a number of long standing bugs caused by the old design. This introduces new ``Node.iter_markers(name)`` and ``Node.get_closest_mark(name)`` APIs. Users are **strongly encouraged** to read the `reasons for the revamp in the docs <https://docs.pytest.org/en/latest/mark.htmlmarker-revamp-and-iteration>`_, or jump over to details about `updating existing code to use the new APIs <https://docs.pytest.org/en/latest/mark.htmlupdating-code>`_. (`3317 <https://github.com/pytest-dev/pytest/issues/3317>`_) - Now when ``pytest.fixture`` is applied more than once to the same function a ``ValueError`` is raised. This buggy behavior would cause surprising problems and if was working for a test suite it was mostly by accident. (`2334 <https://github.com/pytest-dev/pytest/issues/2334>`_) - Support for Python 3.7's builtin ``breakpoint()`` method, see `Using the builtin breakpoint function <https://docs.pytest.org/en/latest/usage.htmlbreakpoint-builtin>`_ for details. (`3180 <https://github.com/pytest-dev/pytest/issues/3180>`_) - ``monkeypatch`` now supports a ``context()`` function which acts as a context manager which undoes all patching done within the ``with`` block. (`3290 <https://github.com/pytest-dev/pytest/issues/3290>`_) - The ``--pdb`` option now causes KeyboardInterrupt to enter the debugger, instead of stopping the test session. On python 2.7, hitting CTRL+C again exits the debugger. On python 3.2 and higher, use CTRL+D. (`3299 <https://github.com/pytest-dev/pytest/issues/3299>`_) - pytest not longer changes the log level of the root logger when the ``log-level`` parameter has greater numeric value than that of the level of the root logger, which makes it play better with custom logging configuration in user code. (`3307 <https://github.com/pytest-dev/pytest/issues/3307>`_) Bug Fixes --------- - A rare race-condition which might result in corrupted ``.pyc`` files on Windows has been hopefully solved. (`3008 <https://github.com/pytest-dev/pytest/issues/3008>`_) - Also use iter_marker for discovering the marks applying for marker expressions from the cli to avoid the bad data from the legacy mark storage. (`3441 <https://github.com/pytest-dev/pytest/issues/3441>`_) - When showing diffs of failed assertions where the contents contain only whitespace, escape them using ``repr()`` first to make it easy to spot the differences. (`3443 <https://github.com/pytest-dev/pytest/issues/3443>`_) Improved Documentation ---------------------- - Change documentation copyright year to a range which auto-updates itself each time it is published. (`3303 <https://github.com/pytest-dev/pytest/issues/3303>`_) Trivial/Internal Changes ------------------------ - ``pytest`` now depends on the `python-atomicwrites <https://github.com/untitaker/python-atomicwrites>`_ library. (`3008 <https://github.com/pytest-dev/pytest/issues/3008>`_) - Update all pypi.python.org URLs to pypi.org. (`3431 <https://github.com/pytest-dev/pytest/issues/3431>`_) - Detect `pytest_` prefixed hooks using the internal plugin manager since ``pluggy`` is deprecating the ``implprefix`` argument to ``PluginManager``. (`3487 <https://github.com/pytest-dev/pytest/issues/3487>`_) - Import ``Mapping`` and ``Sequence`` from ``_pytest.compat`` instead of directly from ``collections`` in ``python_api.py::approx``. Add ``Mapping`` to ``_pytest.compat``, import it from ``collections`` on python 2, but from ``collections.abc`` on Python 3 to avoid a ``DeprecationWarning`` on Python 3.7 or newer. (`3497 <https://github.com/pytest-dev/pytest/issues/3497>`_) ``` ### 3.5.1 ``` ========================= Bug Fixes --------- - Reset ``sys.last_type``, ``sys.last_value`` and ``sys.last_traceback`` before each test executes. Those attributes are added by pytest during the test run to aid debugging, but were never reset so they would create a leaking reference to the last failing test's frame which in turn could never be reclaimed by the garbage collector. (`2798 <https://github.com/pytest-dev/pytest/issues/2798>`_) - ``pytest.raises`` now raises ``TypeError`` when receiving an unknown keyword argument. (`3348 <https://github.com/pytest-dev/pytest/issues/3348>`_) - ``pytest.raises`` now works with exception classes that look like iterables. (`3372 <https://github.com/pytest-dev/pytest/issues/3372>`_) Improved Documentation ---------------------- - Fix typo in ``caplog`` fixture documentation, which incorrectly identified certain attributes as methods. (`3406 <https://github.com/pytest-dev/pytest/issues/3406>`_) Trivial/Internal Changes ------------------------ - Added a more indicative error message when parametrizing a function whose argument takes a default value. (`3221 <https://github.com/pytest-dev/pytest/issues/3221>`_) - Remove internal ``_pytest.terminal.flatten`` function in favor of ``more_itertools.collapse``. (`3330 <https://github.com/pytest-dev/pytest/issues/3330>`_) - Import some modules from ``collections.abc`` instead of ``collections`` as the former modules trigger ``DeprecationWarning`` in Python 3.7. (`3339 <https://github.com/pytest-dev/pytest/issues/3339>`_) - record_property is no longer experimental, removing the warnings was forgotten. (`3360 <https://github.com/pytest-dev/pytest/issues/3360>`_) - Mention in documentation and CLI help that fixtures with leading ``_`` are printed by ``pytest --fixtures`` only if the ``-v`` option is added. (`3398 <https://github.com/pytest-dev/pytest/issues/3398>`_) ``` ### 3.5.0 ``` ========================= Deprecations and Removals ------------------------- - ``record_xml_property`` fixture is now deprecated in favor of the more generic ``record_property``. (`2770 <https://github.com/pytest-dev/pytest/issues/2770>`_) - Defining ``pytest_plugins`` is now deprecated in non-top-level conftest.py files, because they "leak" to the entire directory tree. (`3084 <https://github.com/pytest-dev/pytest/issues/3084>`_) Features -------- - New ``--show-capture`` command-line option that allows to specify how to display captured output when tests fail: ``no``, ``stdout``, ``stderr``, ``log`` or ``all`` (the default). (`1478 <https://github.com/pytest-dev/pytest/issues/1478>`_) - New ``--rootdir`` command-line option to override the rules for discovering the root directory. See `customize <https://docs.pytest.org/en/latest/customize.html>`_ in the documentation for details. (`1642 <https://github.com/pytest-dev/pytest/issues/1642>`_) - Fixtures are now instantiated based on their scopes, with higher-scoped fixtures (such as ``session``) being instantiated first than lower-scoped fixtures (such as ``function``). The relative order of fixtures of the same scope is kept unchanged, based in their declaration order and their dependencies. (`2405 <https://github.com/pytest-dev/pytest/issues/2405>`_) - ``record_xml_property`` renamed to ``record_property`` and is now compatible with xdist, markers and any reporter. ``record_xml_property`` name is now deprecated. (`2770 <https://github.com/pytest-dev/pytest/issues/2770>`_) - New ``--nf``, ``--new-first`` options: run new tests first followed by the rest of the tests, in both cases tests are also sorted by the file modified time, with more recent files coming first. (`3034 <https://github.com/pytest-dev/pytest/issues/3034>`_) - New ``--last-failed-no-failures`` command-line option that allows to specify the behavior of the cache plugin's --last-failed`` feature when no tests failed in the last run (or no cache was found): ``none`` or ``all`` (the default). (`3139 <https://github.com/pytest-dev/pytest/issues/3139>`_) - New ``--doctest-continue-on-failure`` command-line option to enable doctests to show multiple failures for each snippet, instead of stopping at the first failure. (`3149 <https://github.com/pytest-dev/pytest/issues/3149>`_) - Captured log messages are added to the ``<system-out>`` tag in the generated junit xml file if the ``junit_logging`` ini option is set to ``system-out``. If the value of this ini option is ``system-err``, the logs are written to ``<system-err>``. The default value for ``junit_logging`` is ``no``, meaning captured logs are not written to the output file. (`3156 <https://github.com/pytest-dev/pytest/issues/3156>`_) - Allow the logging plugin to handle ``pytest_runtest_logstart`` and ``pytest_runtest_logfinish`` hooks when live logs are enabled. (`3189 <https://github.com/pytest-dev/pytest/issues/3189>`_) - Passing ``--log-cli-level`` in the command-line now automatically activates live logging. (`3190 <https://github.com/pytest-dev/pytest/issues/3190>`_) - Add command line option ``--deselect`` to allow deselection of individual tests at collection time. (`3198 <https://github.com/pytest-dev/pytest/issues/3198>`_) - Captured logs are printed before entering pdb. (`3204 <https://github.com/pytest-dev/pytest/issues/3204>`_) - Deselected item count is now shown before tests are run, e.g. ``collected X items / Y deselected``. (`3213 <https://github.com/pytest-dev/pytest/issues/3213>`_) - The builtin module ``platform`` is now available for use in expressions in ``pytest.mark``. (`3236 <https://github.com/pytest-dev/pytest/issues/3236>`_) - The *short test summary info* section now is displayed after tracebacks and warnings in the terminal. (`3255 <https://github.com/pytest-dev/pytest/issues/3255>`_) - New ``--verbosity`` flag to set verbosity level explicitly. (`3296 <https://github.com/pytest-dev/pytest/issues/3296>`_) - ``pytest.approx`` now accepts comparing a numpy array with a scalar. (`3312 <https://github.com/pytest-dev/pytest/issues/3312>`_) Bug Fixes --------- - Suppress ``IOError`` when closing the temporary file used for capturing streams in Python 2.7. (`2370 <https://github.com/pytest-dev/pytest/issues/2370>`_) - Fixed ``clear()`` method on ``caplog`` fixture which cleared ``records``, but not the ``text`` property. (`3297 <https://github.com/pytest-dev/pytest/issues/3297>`_) - During test collection, when stdin is not allowed to be read, the ``DontReadFromStdin`` object still allow itself to be iterable and resolved to an iterator without crashing. (`3314 <https://github.com/pytest-dev/pytest/issues/3314>`_) Improved Documentation ---------------------- - Added a `reference <https://docs.pytest.org/en/latest/reference.html>`_ page to the docs. (`1713 <https://github.com/pytest-dev/pytest/issues/1713>`_) Trivial/Internal Changes ------------------------ - Change minimum requirement of ``attrs`` to ``17.4.0``. (`3228 <https://github.com/pytest-dev/pytest/issues/3228>`_) - Renamed example directories so all tests pass when ran from the base directory. (`3245 <https://github.com/pytest-dev/pytest/issues/3245>`_) - Internal ``mark.py`` module has been turned into a package. (`3250 <https://github.com/pytest-dev/pytest/issues/3250>`_) - ``pytest`` now depends on the `more-itertools <https://github.com/erikrose/more-itertools>`_ package. (`3265 <https://github.com/pytest-dev/pytest/issues/3265>`_) - Added warning when ``[pytest]`` section is used in a ``.cfg`` file passed with ``-c`` (`3268 <https://github.com/pytest-dev/pytest/issues/3268>`_) - ``nodeids`` can now be passed explicitly to ``FSCollector`` and ``Node`` constructors. (`3291 <https://github.com/pytest-dev/pytest/issues/3291>`_) - Internal refactoring of ``FormattedExcinfo`` to use ``attrs`` facilities and remove old support code for legacy Python versions. (`3292 <https://github.com/pytest-dev/pytest/issues/3292>`_) - Refactoring to unify how verbosity is handled internally. (`3296 <https://github.com/pytest-dev/pytest/issues/3296>`_) - Internal refactoring to better integrate with argparse. (`3304 <https://github.com/pytest-dev/pytest/issues/3304>`_) - Fix a python example when calling a fixture in doc/en/usage.rst (`3308 <https://github.com/pytest-dev/pytest/issues/3308>`_) ``` ### 3.4.2 ``` ========================= Bug Fixes --------- - Removed progress information when capture option is ``no``. (`3203 <https://github.com/pytest-dev/pytest/issues/3203>`_) - Refactor check of bindir from ``exists`` to ``isdir``. (`3241 <https://github.com/pytest-dev/pytest/issues/3241>`_) - Fix ``TypeError`` issue when using ``approx`` with a ``Decimal`` value. (`3247 <https://github.com/pytest-dev/pytest/issues/3247>`_) - Fix reference cycle generated when using the ``request`` fixture. (`3249 <https://github.com/pytest-dev/pytest/issues/3249>`_) - ``[tool:pytest]`` sections in ``*.cfg`` files passed by the ``-c`` option are now properly recognized. (`3260 <https://github.com/pytest-dev/pytest/issues/3260>`_) Improved Documentation ---------------------- - Add logging plugin to plugins list. (`3209 <https://github.com/pytest-dev/pytest/issues/3209>`_) Trivial/Internal Changes ------------------------ - Fix minor typo in fixture.rst (`3259 <https://github.com/pytest-dev/pytest/issues/3259>`_) ``` ### 3.4.1 ``` ========================= Bug Fixes --------- - Move import of ``doctest.UnexpectedException`` to top-level to avoid possible errors when using ``--pdb``. (`1810 <https://github.com/pytest-dev/pytest/issues/1810>`_) - Added printing of captured stdout/stderr before entering pdb, and improved a test which was giving false negatives about output capturing. (`3052 <https://github.com/pytest-dev/pytest/issues/3052>`_) - Fix ordering of tests using parametrized fixtures which can lead to fixtures being created more than necessary. (`3161 <https://github.com/pytest-dev/pytest/issues/3161>`_) - Fix bug where logging happening at hooks outside of "test run" hooks would cause an internal error. (`3184 <https://github.com/pytest-dev/pytest/issues/3184>`_) - Detect arguments injected by ``unittest.mock.patch`` decorator correctly when pypi ``mock.patch`` is installed and imported. (`3206 <https://github.com/pytest-dev/pytest/issues/3206>`_) - Errors shown when a ``pytest.raises()`` with ``match=`` fails are now cleaner on what happened: When no exception was raised, the "matching '...'" part got removed as it falsely implies that an exception was raised but it didn't match. When a wrong exception was raised, it's now thrown (like ``pytest.raised()`` without ``match=`` would) instead of complaining about the unmatched text. (`3222 <https://github.com/pytest-dev/pytest/issues/3222>`_) - Fixed output capture handling in doctests on macOS. (`985 <https://github.com/pytest-dev/pytest/issues/985>`_) Improved Documentation ---------------------- - Add Sphinx parameter docs for ``match`` and ``message`` args to ``pytest.raises``.

Changelog
### 1.15.0 ``` ========================== Highlights ========== * NumPy has switched to pytest for testing. New functions ============= * `np.gcd` and `np.lcm`, to compute the greatest common divisor and least common multiple. * `np.ma.stack`, the `np.stack` array-joining function generalized to masked arrays. * ``quantile`` function, an interface to ``percentile`` without factors of 100 * ``nanquantile`` function, an interface to ``nanpercentile`` without factors of 100 * `np.printoptions`, a context manager that sets print options temporarily for the scope of the ``with`` block:: >>> with np.printoptions(precision=2): ... print(np.array([2.0]) / 3) [0.67] * `np.histogram_bin_edges`, a function to get the edges of the bins used by a histogram without needing to calculate the histogram. * `npy_get_floatstatus_barrier`` and ``npy_clear_floatstatus_barrier`` have been added to deal with compiler optimization changing the order of operations. See below for details. Deprecations ============ * Aliases of builtin `pickle` functions are deprecated, in favor of their unaliased ``pickle.<func>`` names: * `np.loads` * `np.core.numeric.load` * `np.core.numeric.loads` * `np.ma.loads`, `np.ma.dumps` * `np.ma.load`, `np.ma.dump` - these functions already failed on python 3, when called with a string. * Multidimensional indexing with anything but a tuple is deprecated. This means that code such as ``ind = [slice(None), 0]``, ``arr[[slice(None), 0]]`` should be changed to ``arr[tuple(ind)]``. This is necessary to avoid ambiguity in expressions such as ``arr[[[0, 1], [0, 1]]]`` which currently is interpreted as ``arr[array([0, 1]), array([0, 1])]``. In future, this will be interpreted as ``arr[array([[0, 1], [0, 1]])]``. * Direct imports from the following modules is deprecated. All testing related imports should come from `numpy.testing`. * `np.testing.utils` * `np.testing.decorators` * `np.testing.nosetester` * `np.testing.noseclasses` * `np.core.umath_tests` * Giving a generator to `np.sum` is now deprecated. This was undocumented, but worked. Previously, it would calculate the sum of the generator expression. In the future, it might return a different result. Use `np.sum(np.from_iter(generator))` or the built-in Python `sum` instead. * Users of the C-API should call ``PyArrayResolveWriteBackIfCopy`` or ``PyArray_DiscardWritbackIfCopy`` on any array with the ``WRITEBACKIFCOPY`` flag set, before the array is deallocated. A deprecation warning will be emitted if those calls are not used when needed. * Users of ``nditer`` should use the nditer object as a context manager anytime one of the iterator operands is writeable, so that numpy can manage writeback semantics, or should call ``it.close()``. A `RuntimeWarning` may be emitted otherwise in these cases. * The ``normed`` argument of ``np.histogram``, deprecated long ago in 1.6.0, now emits a ``DeprecationWarning``. Future Changes ============== Compatibility notes =================== The ``NpzFile`` returned by ``np.savez`` is now a `collections.abc.Mapping` --------------------------------------------------------------------------- This means it behaves like a readonly dictionary, and has a new ``.values()`` method and ``len()`` implementation. On python 3, this means that ``.iteritems()``, ``.iterkeys()`` have been deprecated, and ``.keys()`` and ``.items()`` now return views and not lists. This is consistent with how the builtin ``dict`` type changed between python 2 and python 3. Under certain conditions, nditer must be used in a context manager ------------------------------------------------------------------ When using an nditer with the ``"writeonly"`` or ``"readwrite"`` flags, there are some circumstances where nditer doesn't actually give you a view onto the writable array. Instead, it gives you a copy, and if you make changes to the copy, nditer later writes those changes back into your actual array. Currently, this writeback occurs when the array objects are garbage collected, which makes this API error-prone on CPython and entirely broken on PyPy. Therefore, ``nditer`` should now be used as a context manager whenever using ``nditer`` with writeable arrays (``with np.nditer(...) as it: ...``). You may also explicitly call ``it.close()`` for cases where a context manager is unusable, for instance in generator expressions. Numpy has switched to using pytest instead of nose for testing -------------------------------------------------------------- The last nose release was 1.3.7 in June, 2015, and development of that tool has ended, consequently NumPy has now switched to using pytest. The old decorators and nose tools that were previously used by some downstream projects remain available, but will not be maintained. The standard testing utilities, `assert_almost_equal` and such, are not be affected by this change except for the nose specific functions `import_nose` and `raises`. Those functions are not used in numpy, but are kept for downstream compatibility. Numpy no longer monkey-patches ``ctypes`` with ``__array_interface__`` ---------------------------------------------------------------------- Previously numpy added ``__array_interface__`` attributes to all the integer types from ``ctypes``. ``np.ma.notmasked_contiguous`` and ``np.ma.flatnotmasked_contiguous`` always return lists ----------------------------------------------------------------------------------------- This was always the documented behavior, but in reality the result used to be any of slice, None, or list. All downstream users seem to use detect the `None` result from ``flatnotmasked_contiguous`` and replace it with ``[]``. These callers will continue to work as before. ``np.squeeze`` now respects the API expectation of objects that do not handle an ``axis`` argument -------------------------------------------------------------------------------------------------- Prior to version ``1.7.0`` ``np.squeeze`` did not have an ``axis`` argument and all empty axes were removed by default. After incorporation of an ``axis`` argument, it was possible to selectively squeeze single or multiple empty axes, but the old API expectation was not respected because the axes could still be selectively removed (silent success) in an object depending on the old API. The silent success is no longer possible, and objects expecting the old API are respected. The silent success was prevented by removing the interception of an otherwise-normal Exception when ``axis`` was provided to an object using the old API. unstructured void array's ``.item`` method now returns a bytes object --------------------------------------------------------------------- ``.item`` now returns a ``bytes`` object instead of a buffer or byte array. This may affect code which assumed the return value was mutable, which is no longer the case. ``copy.copy`` and ``copy.deepcopy`` no longer turn ``masked`` into an array ---------------------------------------------------------------------------- Since ``np.ma.masked`` is a readonly scalar, copying should be a no-op. These functions now behave consistently with ``np.copy()``. Multifield Indexing of Structured Arrays will still return a copy ----------------------------------------------------------------- The change that multi-field indexing of structured arrays returns a view instead of a copy is pushed back to 1.16. A new method ``numpy.lib.recfunctions.repack_fields`` has been introduced to help mitigate the effects of this change, which can be used to write code compatible with both numpy 1.15 and 1.16. For more information on how to update code to account for this future change see "basics/structured arrays/accessing multiple fields" in the user guide. C API changes ============= * Functions ``npy_get_floatstatus_barrier`` and ``npy_clear_floatstatus_barrier`` have been added and should be used in place of the ``npy_get_floatstatus``and ``npy_clear_status`` functions. Optimizing compilers like GCC 8.1 and Clang were rearranging the order of operations when the previous functions were used in the ufunc SIMD functions, resulting in the floatstatus flags being ' checked before the operation whose status we wanted to check was run. See `10339 <https://github.com/numpy/numpy/issues/10370>`__. * ``PyArray_GetDTypeTransferFunction`` now defaults to using user-defined ``copyswapn`` / ``copyswap`` for user-defined dtypes. If this causes a significant performance hit, consider implementing ``copyswapn`` to reflect the implementation of ``PyArray_GetStridedCopyFn``. See `10898 <https://github.com/numpy/numpy/pull/10898>`__. New Features ============ ``np.gcd`` and ``np.lcm`` ufuncs added for integer and objects types -------------------------------------------------------------------- These compute the greatest common divisor, and lowest common multiple, respectively. These work on all the numpy integer types, as well as the builtin arbitrary-precision `Decimal` and `long` types. Support for cross-platform builds for iOS ----------------------------------------- The build system has been modified to add support for the ``_PYTHON_HOST_PLATFORM`` environment variable, used by ``distutils`` when compiling on one platform for another platform. This makes it possible to compile NumPy for iOS targets. This only enables you to compile NumPy for one specific platform at a time. Creating a full iOS-compatible NumPy package requires building for the 5 architectures supported by iOS (i386, x86_64, armv7, armv7s and arm64), and combining these 5 compiled builds products into a single "fat" binary. ``return_indices`` keyword added for ``np.intersect1d`` ------------------------------------------------------- New keyword ``return_indices`` returns the indices of the two input arrays that correspond to the common elements. ``np.quantile`` and ``np.nanquantile`` -------------------------------------- Like ``np.percentile`` and ``np.nanpercentile``, but takes quantiles in [0, 1] rather than percentiles in [0, 100]. ``np.percentile`` is now a thin wrapper around ``np.quantile`` with the extra step of dividing by 100. Build system ------------ Added experimental support for the 64-bit RISC-V architecture. Improvements ============ ``np.ufunc.reduce`` and related functions now accept an initial value --------------------------------------------------------------------- ``np.ufunc.reduce``, ``np.sum``, ``np.prod``, ``np.min`` and ``np.max`` all now accept an ``initial`` keyword argument that specifies the value to start the reduction with. ``np.flip`` can operate over multiple axes ------------------------------------------ ``np.flip`` now accepts None, or tuples of int, in its ``axis`` argument. If axis is None, it will flip over all the axes. ``histogram`` and ``histogramdd`` functions have moved to ``np.lib.histograms`` ------------------------------------------------------------------------------ These were originally found in ``np.lib.function_base``. They are still available under their un-scoped ``np.histogram(dd)`` names, and to maintain compatibility, aliased at ``np.lib.function_base.histogram(dd)``. Code that does ``from np.lib.function_base import *`` will need to be updated with the new location, and should consider not using ``import *`` in future. ``histogram`` will accept NaN values when explicit bins are given ----------------------------------------------------------------- Previously it would fail when trying to compute a finite range for the data. Since the range is ignored anyway when the bins are given explicitly, this error was needless. Note that calling `histogram` on NaN values continues to raise the `RuntimeWarning`s typical of working with nan values, which can be silenced as usual with `errstate`. ``histogram`` works on datetime types, when explicit bin edges are given ------------------------------------------------------------------------ Dates, times, and timedeltas can now be histogrammed. The bin edges must be passed explicitly, and are not yet computed automatically. ``histogram`` "auto" estimator handles limited variance better ------------------------------------------------------------------------ No longer does an IQR of 0 result in `n_bins=1`, rather the number of bins chosen is related to the data size in this situation. ``histogram`` and ``histogramdd`` return edges matching the float type of the data ---------------------------------------------------------------------------------- When passed ``float16``, ``np.float32``, or ``np.longdouble`` data, the returned edges are now of the same dtype. Previously, ``histogram`` would only return the same type if explicit bins were given, and ``histogram`` would produce ``float64`` bins no matter what the inputs. ``histogramdd`` allows explicit ranges to be given in a subset of axes ---------------------------------------------------------------------- The ``range`` argument of `histogramdd` can now contain ``None`` values to indicate that the range for the corresponding axis should be computed from the data. Previously, this could not be specified on a per-axis basis. The normed arguments of ``histogramdd`` and ``histogram2d`` have been renamed ----------------------------------------------------------------------------- These arguments are now called ``density``, which is consistent with ``histogram``. The old argument continues to work, but the new name should be preferred. ``np.r_`` works with 0d arrays, and ``np.ma.mr_`` works with ``np.ma.masked`` ---------------------------------------------------------------------------- 0d arrays passed to the `r_` and `mr_` concatenation helpers are now treated as though they are arrays of length 1. Previously, passing these was an error. As a result, ``np.ma.mr_`` now works correctly on the ``masked`` constant. ``np.ptp`` accepts a ``keepdims`` argument, and extended axis tuples -------------------------------------------------------------------- ``np.ptp`` (peak-to-peak) can now work over multiple axes, just like `max` and `min`. ``MaskedArray.astype`` now is identical to ``ndarray.astype`` ------------------------------------------------------------- This means it takes all the same arguments, making more code written for ndarray work for masked array too. Enable AVX2/AVX512 at compile time ------------------------------------------------------------- Change to simd.inc.src to use AVX2 or AVX512 at compile time. Solving the gap that if compile numpy for avx2 (or 512) with -march=native, still get the SSE code for the simd functions even though rest of the code gets AVX2. ``nan_to_num`` always returns scalars when receiving scalar or 0d inputs ------------------------------------------------------------------------ Previously an array was returned for integer scalar inputs, which is inconsistent with the behavior for float inputs, and that of ufuncs in general. For all types of scalar or 0d input, the result is now a scalar. ``np.flatnonzero`` works on numpy-convertible types --------------------------------------------------- ``np.flatnonzero`` now uses ``np.ravel(a)`` instead of ``a.ravel()``, so it works for lists, tuples, etc. ``np.interp`` returns numpy scalars rather than builtin scalars --------------------------------------------------------------- Previously ``np.interp(0.5, [0, 1], [10, 20])`` would return a ``float``, but now it returns a ``np.float64`` object, which more closely matches the behavior of other functions. Additionally, the special case of ``np.interp(object_array_0d, ...)`` is no longer supported, as ``np.interp(object_array_nd)`` was never supported anyway. As a result of this change, the ``period`` argument can now be used on 0d arrays. Allow dtype field names to be unicode in Python 2 --------------------------------------------------------------- Previously ``np.dtype([(u'name', float)])`` would raise a ``TypeError`` in Python 2, as only bytestrings were allowed in field names. Now any unicode string field names will be encoded with the ``ascii`` codec, raising a ``UnicodeEncodeError`` upon failure. This change makes it easier to write Python 2/3 compatible code using ``from __future__ import unicode_literals``, which previously would cause string literal field names to raise a TypeError in Python 2. Comparison ufuncs accept ``dtype=object``, overriding the default ``bool`` -------------------------------------------------------------------------- This allows object arrays of symbolic types, which override ``==`` and other operators to return expressions, to be compared elementwise with ``np.equal(a, b, dtype=object)``. ``sort`` functions accept ``kind='stable'`` ------------------------------------------- Up until now, to perform a stable sort on the data, the user must do: >>> np.sort([5, 2, 6, 2, 1], kind='mergesort') [1, 2, 2, 5, 6] because merge sort is the only stable sorting algorithm available in NumPy. However, having kind='mergesort' does not make it explicit that the user wants to perform a stable sort thus harming the readability. This change allows the user to specify kind='stable' thus clarifying the intent. Do not make temporary copies for in-place accumulation ------------------------------------------------------ When ufuncs perform accumulation they no longer make temporary copies because of the overlap between input an output, that is, the next element accumulated is added before the accumulated result is stored in its place, hence the overlap is safe. Avoiding the copy results in faster execution. ``linalg.matrix_power`` can now handle stacks of matrices --------------------------------------------------------- Like other functions in ``linalg``, ``matrix_power`` can now deal with arrays of dimension larger than 2, which are treated as stacks of matrices. As part of the change, to further improve consistency, the name of the first argument has been changed to ``a`` (from ``M``), and the exceptions for non-square matrices have been changed to ``LinAlgError`` (from ``ValueError``). Increased performance in ``random.permutation`` for multidimensional arrays --------------------------------------------------------------------------- ``permutation`` uses the fast path in ``random.shuffle`` for all input array dimensions. Previously the fast path was only used for 1-d arrays. Generalized ufuncs now accept ``axes``, ``axis`` and ``keepdims`` arguments --------------------------------------------------------------------------- One can control over which axes a generalized ufunc operates by passing in an ``axes`` argument, a list of tuples with indices of particular axes. For instance, for a signature of ``(i,j),(j,k)->(i,k)`` appropriate for matrix multiplication, the base elements are two-dimensional matrices and these are taken to be stored in the two last axes of each argument. The corresponding axes keyword would be ``[(-2, -1), (-2, -1), (-2, -1)]``. If one wanted to use leading dimensions instead, one would pass in ``[(0, 1), (0, 1), (0, 1)]``. For simplicity, for generalized ufuncs that operate on 1-dimensional arrays (vectors), a single integer is accepted instead of a single-element tuple, and for generalized ufuncs for which all outputs are scalars, the (empty) output tuples can be omitted. Hence, for a signature of ``(i),(i)->()`` appropriate for an inner product, one could pass in ``axes=[0, 0]`` to indicate that the vectors are stored in the first dimensions of the two inputs arguments. As a short-cut for generalized ufuncs that are similar to reductions, i.e., that act on a single, shared core dimension such as the inner product example above, one can pass an ``axis`` argument. This is equivalent to passing in ``axes`` with identical entries for all arguments with that core dimension (e.g., for the example above, ``axes=[(axis,), (axis,)]``). Furthermore, like for reductions, for generalized ufuncs that have inputs that all have the same number of core dimensions and outputs with no core dimension, one can pass in ``keepdims`` to leave a dimension with size 1 in the outputs, thus allowing proper broadcasting against the original inputs. The location of the extra dimension can be controlled with ``axes``. For instance, for the inner-product example, ``keepdims=True, axes=[-2, -2, -2]`` would act on the inner-product example, ``keepdims=True, axis=-2`` would act on the one-but-last dimension of the input arguments, and leave a size 1 dimension in that place in the output. float128 values now print correctly on ppc systems -------------------------------------------------- Previously printing float128 values was buggy on ppc, since the special double-double floating-point-format on these systems was not accounted for. float128s now print with correct rounding and uniqueness. Warning to ppc users: You should upgrade glibc if it is version <=2.23, especially if using float128. On ppc, glibc's malloc in these version often misaligns allocated memory which can crash numpy when using float128 values. New ``np.take_along_axis`` and ``np.put_along_axis`` functions -------------------------------------------------------------- When used on multidimensional arrays, ``argsort``, ``argmin``, ``argmax``, and ``argpartition`` return arrays that are difficult to use as indices. ``take_along_axis`` provides an easy way to use these indices to lookup values within an array, so that:: np.take_along_axis(a, np.argsort(a, axis=axis), axis=axis) is the same as:: np.sort(a, axis=axis) ``np.put_along_axis`` acts as the dual operation for writing to these indices within an array. .. note:: Implementations of ``__array_ufunc__`` should ensure that they can handle either ``axis`` or ``axes``. In future, we may convert ``axis`` to ``axes`` before passing it on. Changes ======= ========================== ``` ### 1.14.5 ``` ========================== This is a bugfix release for bugs reported following the 1.14.4 release. The most significant fixes are: * fixes for compilation errors on alpine and NetBSD The Python versions supported in this release are 2.7 and 3.4 - 3.6. The Python 3.6 wheels available from PIP are built with Python 3.6.2 and should be compatible with all previous versions of Python 3.6. The source releases were cythonized with Cython 0.28.2 and should work for the upcoming Python 3.7. Contributors ============ A total of 1 person contributed to this release. People with a "+" by their names contributed a patch for the first time. * Charles Harris Pull requests merged ==================== A total of 2 pull requests were merged for this release. * `11274 <https://github.com/numpy/numpy/pull/11274>`__: BUG: Correct use of NPY_UNUSED. * `11294 <https://github.com/numpy/numpy/pull/11294>`__: BUG: Remove extra trailing parentheses. ========================= ``` ### 1.14.4 ``` ========================== This is a bugfix release for bugs reported following the 1.14.3 release. The most significant fixes are: * fixes for compiler instruction reordering that resulted in NaN's not being properly propagated in `np.max` and `np.min`, * fixes for bus faults on SPARC and older ARM due to incorrect alignment checks. There are also improvements to printing of long doubles on PPC platforms. All is not yet perfect on that platform, the whitespace padding is still incorrect and is to be fixed in numpy 1.15, consequently NumPy still fails some printing-related (and other) unit tests on ppc systems. However, the printed values are now correct. Note that NumPy will error on import if it detects incorrect float32 `dot` results. This problem has been seen on the Mac when working in the Anaconda enviroment and is due to a subtle interaction between MKL and PyQt5. It is not strictly a NumPy problem, but it is best that users be aware of it. See the gh-8577 NumPy issue for more information. The Python versions supported in this release are 2.7 and 3.4 - 3.6.

The major problems fixed are the following. * Problems with the new array printing, particularly the printing of complex values, Please report any additional problems that may turn up. * Problems with ``np.einsum`` due to the new ``optimized=True`` default. Some fixes for optimization have been applied and ``optimize=False`` is now the default. * The sort order in ``np.unique`` when ``axis=<some-number>`` will now always be lexicographic in the subarray elements. In previous NumPy versions there was an optimization that could result in sorting the subarrays as unsigned byte strings. * The change in 1.14.0 that multi-field indexing of structured arrays returns a view instead of a copy has been reverted but remains on track for NumPy 1.15. Affected users should read the 1.14.1 Numpy User Guide section "basics/structured arrays/accessing multiple fields" for advice on how to manage this transition. The Python versions supported in this release are 2.7 and 3.4 - 3.6. The Python 3.6 wheels available from PIP are built with Python 3.6.2 and should be compatible with all previous versions of Python 3.6. The source releases were cythonized with Cython 0.26.1, which is known to **not** support the upcoming Python 3.7 release. People who wish to run Python 3.7 should check out the NumPy repo and try building with the, as yet, unreleased master branch of Cython.
