Changelog
### 1.8.0
```
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with ``python -Wd`` and check for ``DeprecationWarning`` s).
Our development attention will now shift to bug-fix releases on the
1.8.x branch, and on adding new features on the master branch.
This release requires Python `3.8`+ and NumPy `1.17.3` or greater.
For running on PyPy, PyPy3 `6.0`+ is required.
Highlights of this release
-------------------------
- A sparse array API has been added for early testing and feedback; this
work is ongoing, and users should expect minor API refinements over
the next few releases.
- The sparse SVD library PROPACK is now vendored with SciPy, and an interface
is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``.
- A new `scipy.stats.sampling` submodule that leverages the ``UNU.RAN`` C
library to sample from arbitrary univariate non-uniform continuous and
discrete distributions
- All namespaces that were private but happened to miss underscores in
their names have been deprecated.
New features
-------------
`scipy.fft` improvements
========================
Added an ``orthogonalize=None`` parameter to the real transforms in `scipy.fft`
which controls whether the modified definition of DCT/DST is used without
changing the overall scaling.
`scipy.fft` backend registration is now smoother, operating with a single
registration call and no longer requiring a context manager.
`scipy.integrate` improvements
==============================
`scipy.integrate.quad_vec` introduces a new optional keyword-only argument,
``args``. ``args`` takes in a tuple of extra arguments if any (default is
``args=()``), which is then internally used to pass into the callable function
(needing these extra arguments) which we wish to integrate.
`scipy.interpolate` improvements
================================
`scipy.interpolate.BSpline` has a new method, ``design_matrix``, which
constructs a design matrix of b-splines in the sparse CSR format.
A new method ``from_cubic`` in ``BSpline`` class allows to convert a
``CubicSpline`` object to ``BSpline`` object.
`scipy.linalg` improvements
===========================
`scipy.linalg` gained three new public array structure investigation functions.
`scipy.linalg.bandwidth` returns information about the bandedness of an array
and can be used to test for triangular structure discovery, while
`scipy.linalg.issymmetric` and `scipy.linalg.ishermitian` test the array for
exact and approximate symmetric/Hermitian structure.
`scipy.optimize` improvements
=============================
`scipy.optimize.check_grad` introduces two new optional keyword only arguments,
``direction`` and ``seed``. ``direction`` can take values, ``'all'`` (default),
in which case all the one hot direction vectors will be used for verifying
the input analytical gradient function and ``'random'``, in which case a
random direction vector will be used for the same purpose. ``seed``
(default is ``None``) can be used for reproducing the return value of
``check_grad`` function. It will be used only when ``direction='random'``.
The `scipy.optimize.minimize` ``TNC`` method has been rewritten to use Cython
bindings. This also fixes an issue with the callback altering the state of the
optimization.
Added optional parameters ``target_accept_rate`` and ``stepwise_factor`` for
adapative step size adjustment in ``basinhopping``.
The ``epsilon`` argument to ``approx_fprime`` is now optional so that it may
have a default value consistent with most other functions in `scipy.optimize`.
`scipy.signal` improvements
===========================
Add ``analog`` argument, default ``False``, to ``zpk2sos``, and add new pairing
option ``'minimal'`` to construct analog and minimal discrete SOS arrays.
``tf2sos`` uses zpk2sos; add ``analog`` argument here as well, and pass it on
to ``zpk2sos``.
``savgol_coeffs`` and ``savgol_filter`` now work for even window lengths.
Added the Chirp Z-transform and Zoom FFT available as `scipy.signal.CZT` and
`scipy.signal.ZoomFFT`.
`scipy.sparse` improvements
===========================
An array API has been added for early testing and feedback; this
work is ongoing, and users should expect minor API refinements over
the next few releases. Please refer to the `scipy.sparse`
docstring for more information.
``maximum_flow`` introduces optional keyword only argument, ``method``
which accepts either, ``'edmonds-karp'`` (Edmonds Karp algorithm) or
``'dinic'`` (Dinic's algorithm). Moreover, ``'dinic'`` is used as default
value for ``method`` which means that Dinic's algorithm is used for computing
maximum flow unless specified. See, the comparison between the supported
algorithms in
`this comment <https://github.com/scipy/scipy/pull/14358#issue-684212523>`_.
Parameters ``atol``, ``btol`` now default to 1e-6 in
`scipy.sparse.linalg.lsmr` to match with default values in
`scipy.sparse.linalg.lsqr`.
Add the Transpose-Free Quasi-Minimal Residual algorithm (TFQMR) for general
nonsingular non-Hermitian linear systems in `scipy.sparse.linalg.tfqmr`.
The sparse SVD library PROPACK is now vendored with SciPy, and an interface is
exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. For some problems,
this may be faster and/or more accurate than the default, ARPACK.
``sparse.linalg`` iterative solvers now have a nonzero initial guess option,
which may be specified as ``x0 = 'Mb'``.
The ``trace`` method has been added for sparse matrices.
`scipy.spatial` improvements
============================
`scipy.spatial.transform.Rotation` now supports item assignment and has a new
``concatenate`` method.
Add `scipy.spatial.distance.kulczynski1` in favour of
`scipy.spatial.distance.kulsinski` which will be deprecated in the next
release.
`scipy.spatial.distance.minkowski` now also supports ``0<p<1``.
`scipy.special` improvements
============================
The new function `scipy.special.log_expit` computes the logarithm of the
logistic sigmoid function. The function is formulated to provide accurate
results for large positive and negative inputs, so it avoids the problems
that would occur in the naive implementation ``log(expit(x))``.
A suite of five new functions for elliptic integrals:
``scipy.special.ellipr{c,d,f,g,j}``. These are the
`Carlson symmetric elliptic integrals <https://dlmf.nist.gov/19.16>`_, which
have computational advantages over the classical Legendre integrals. Previous
versions included some elliptic integrals from the Cephes library
(``scipy.special.ellip{k,km1,kinc,e,einc}``) but was missing the integral of
third kind (Legendre's Pi), which can be evaluated using the new Carlson
functions. The new Carlson elliptic integral functions can be evaluated in the
complex plane, whereas the Cephes library's functions are only defined for
real inputs.
Several defects in `scipy.special.hyp2f1` have been corrected. Approximately
correct values are now returned for ``z`` near ``exp(+-i*pi/3)``, fixing
`8054 <https://github.com/scipy/scipy/issues/8054>`_. Evaluation for such ``z``
is now calculated through a series derived by
`López and Temme (2013) <https://arxiv.org/abs/1306.2046>`_ that converges in
these regions. In addition, degenerate cases with one or more of ``a``, ``b``,
and/or ``c`` a non-positive integer are now handled in a manner consistent with
`mpmath's hyp2f1 implementation <https://mpmath.org/doc/current/functions/hypergeometric.html>`_,
which fixes `7340 <https://github.com/scipy/scipy/issues/7340>`_. These fixes
were made as part of an effort to rewrite the Fortran 77 implementation of
hyp2f1 in Cython piece by piece. This rewriting is now roughly 50% complete.
`scipy.stats` improvements
==========================
`scipy.stats.qmc.LatinHypercube` introduces two new optional keyword-only
arguments, ``optimization`` and ``strength``. ``optimization`` is either
``None`` or ``random-cd``. In the latter, random permutations are performed to
improve the centered discrepancy. ``strength`` is either 1 or 2. 1 corresponds
to the classical LHS while 2 has better sub-projection properties. This
construction is referred to as an orthogonal array based LHS of strength 2.
In both cases, the output is still a LHS.
`scipy.stats.qmc.Halton` is faster as the underlying Van der Corput sequence
was ported to Cython.
The ``alternative`` parameter was added to the ``kendalltau`` and ``somersd``
functions to allow one-sided hypothesis testing. Similarly, the masked
versions of ``skewtest``, ``kurtosistest``, ``ttest_1samp``, ``ttest_ind``,
and ``ttest_rel`` now also have an ``alternative`` parameter.
Add `scipy.stats.gzscore` to calculate the geometrical z score.
Random variate generators to sample from arbitrary univariate non-uniform
continuous and discrete distributions have been added to the new
`scipy.stats.sampling` submodule. Implementations of a C library
`UNU.RAN <http://statmath.wu.ac.at/software/unuran/>`_ are used for
performance. The generators added are:
- TransformedDensityRejection
- DiscreteAliasUrn
- NumericalInversePolynomial
- DiscreteGuideTable
- SimpleRatioUniforms
The ``binned_statistic`` set of functions now have improved performance for
the ``std``, ``min``, ``max``, and ``median`` statistic calculations.
``somersd`` and ``_tau_b`` now have faster Pythran-based implementations.
Some general efficiency improvements to handling of ``nan`` values in
several ``stats`` functions.
Added the Tukey-Kramer test as `scipy.stats.tukey_hsd`.
Improved performance of `scipy.stats.argus` ``rvs`` method.
Added the parameter ``keepdims`` to `scipy.stats.variation` and prevent the
undesirable return of a masked array from the function in some cases.
``permutation_test`` performs an exact or randomized permutation test of a
given statistic on provided data.
Deprecated features
---------------------
Clear split between public and private API
==========================================
SciPy has always documented what its public API consisted of in
:ref:`its API reference docs <scipy-api>`,
however there never was a clear split between public and
private namespaces in the code base. In this release, all namespaces that were
private but happened to miss underscores in their names have been deprecated.
These include (as examples, there are many more):
- ``scipy.signal.spline``
- ``scipy.ndimage.filters``
- ``scipy.ndimage.fourier``
- ``scipy.ndimage.measurements``
- ``scipy.ndimage.morphology``
- ``scipy.ndimage.interpolation``
- ``scipy.sparse.linalg.solve``
- ``scipy.sparse.linalg.eigen``
- ``scipy.sparse.linalg.isolve``
All functions and other objects in these namespaces that were meant to be
public are accessible from their respective public namespace (e.g.
`scipy.signal`). The design principle is that any public object must be
accessible from a single namespace only; there are a few exceptions, mostly for
historical reasons (e.g., ``stats`` and ``stats.distributions`` overlap).
For other libraries aiming to provide a SciPy-compatible API, it is now
unambiguous what namespace structure to follow. See
`gh-14360 <https://github.com/scipy/scipy/issues/14360>`_ for more details.
Other deprecations
--------------------
``NumericalInverseHermite`` has been deprecated from `scipy.stats` and moved
to the `scipy.stats.sampling` submodule. It now uses the C implementation of
the UNU.RAN library so the result of methods like ``ppf`` may vary slightly.
Parameter ``tol`` has been deprecated and renamed to ``u_resolution``. The
parameter ``max_intervals`` has also been deprecated and will be removed in a
future release of SciPy.
Backwards incompatible changes
----------------------------------
- SciPy has raised the minimum compiler versions to GCC 6.3 on linux and
VS2019 on windows. In particular, this means that SciPy may now use C99 and
C++14 features. For more details see
`here <https://docs.scipy.org/doc/scipy/reference/dev/toolchain.html>`_.
- The result for empty bins for `scipy.stats.binned_statistic` with the builtin
``'std'`` metric is now ``nan``, for consistency with ``np.std``.
- The function `scipy.spatial.distance.wminkowski` has been removed. To achieve
the same results as before, please use the ``minkowski`` distance function
with the (optional) ``w=`` keyword-argument for the given weight.
Other changes
---------------
Some Fortran 77 code was modernized to be compatible with NAG's nagfor Fortran
compiler (see, e.g., `PR 13229 <https://github.com/scipy/scipy/pull/13229>`_).
``threadpoolctl`` may now be used by our test suite to substantially improve
the efficiency of parallel test suite runs.

- ``_BaseHMM`` has been promoted to public API and has been renamed to
``BaseHMM``.
- MultinomialHMM no longer overwrites preset ``n_features``.
- An implementation of the Forward-Backward algorithm based upon scaling
is available by specifying ``implementation="scaling"`` when instantiating
HMMs. In general, the scaling algorithm is more efficient than an
implementation based upon logarithms. See `scripts/benchmark.py` for
a comparison of the performance of the two implementations.
- The *logprob* parameter to `.ConvergenceMonitor.report` has been renamed to
*log_prob*.

New features ------------- `scipy.fft` improvements ======================== Added an ``orthogonalize=None`` parameter to the real transforms in `scipy.fft` which controls whether the modified definition of DCT/DST is used without changing the overall scaling. `scipy.fft` backend registration is now smoother, operating with a single registration call and no longer requiring a context manager. `scipy.integrate` improvements ============================== `scipy.integrate.quad_vec` introduces a new optional keyword-only argument, ``args``. ``args`` takes in a tuple of extra arguments if any (default is ``args=()``), which is then internally used to pass into the callable function (needing these extra arguments) which we wish to integrate. `scipy.interpolate` improvements ================================ `scipy.interpolate.BSpline` has a new method, ``design_matrix``, which constructs a design matrix of b-splines in the sparse CSR format. A new method ``from_cubic`` in ``BSpline`` class allows to convert a ``CubicSpline`` object to ``BSpline`` object. `scipy.linalg` improvements =========================== `scipy.linalg` gained three new public array structure investigation functions. `scipy.linalg.bandwidth` returns information about the bandedness of an array and can be used to test for triangular structure discovery, while `scipy.linalg.issymmetric` and `scipy.linalg.ishermitian` test the array for exact and approximate symmetric/Hermitian structure. `scipy.optimize` improvements ============================= `scipy.optimize.check_grad` introduces two new optional keyword only arguments, ``direction`` and ``seed``. ``direction`` can take values, ``'all'`` (default), in which case all the one hot direction vectors will be used for verifying the input analytical gradient function and ``'random'``, in which case a random direction vector will be used for the same purpose. ``seed`` (default is ``None``) can be used for reproducing the return value of ``check_grad`` function. It will be used only when ``direction='random'``. The `scipy.optimize.minimize` ``TNC`` method has been rewritten to use Cython bindings. This also fixes an issue with the callback altering the state of the optimization. Added optional parameters ``target_accept_rate`` and ``stepwise_factor`` for adapative step size adjustment in ``basinhopping``. The ``epsilon`` argument to ``approx_fprime`` is now optional so that it may have a default value consistent with most other functions in `scipy.optimize`. `scipy.signal` improvements =========================== Add ``analog`` argument, default ``False``, to ``zpk2sos``, and add new pairing option ``'minimal'`` to construct analog and minimal discrete SOS arrays. ``tf2sos`` uses zpk2sos; add ``analog`` argument here as well, and pass it on to ``zpk2sos``. ``savgol_coeffs`` and ``savgol_filter`` now work for even window lengths. Added the Chirp Z-transform and Zoom FFT available as `scipy.signal.CZT` and `scipy.signal.ZoomFFT`. `scipy.sparse` improvements =========================== An array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. Please refer to the `scipy.sparse` docstring for more information. ``maximum_flow`` introduces optional keyword only argument, ``method`` which accepts either, ``'edmonds-karp'`` (Edmonds Karp algorithm) or ``'dinic'`` (Dinic's algorithm). Moreover, ``'dinic'`` is used as default value for ``method`` which means that Dinic's algorithm is used for computing maximum flow unless specified. See, the comparison between the supported algorithms in `this comment <https://github.com/scipy/scipy/pull/14358#issue-684212523>`_. Parameters ``atol``, ``btol`` now default to 1e-6 in `scipy.sparse.linalg.lsmr` to match with default values in `scipy.sparse.linalg.lsqr`. Add the Transpose-Free Quasi-Minimal Residual algorithm (TFQMR) for general nonsingular non-Hermitian linear systems in `scipy.sparse.linalg.tfqmr`. The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. For some problems, this may be faster and/or more accurate than the default, ARPACK. ``sparse.linalg`` iterative solvers now have a nonzero initial guess option, which may be specified as ``x0 = 'Mb'``. The ``trace`` method has been added for sparse matrices. `scipy.spatial` improvements ============================ `scipy.spatial.transform.Rotation` now supports item assignment and has a new ``concatenate`` method. Add `scipy.spatial.distance.kulczynski1` in favour of `scipy.spatial.distance.kulsinski` which will be deprecated in the next release. `scipy.spatial.distance.minkowski` now also supports ``0<p<1``. `scipy.special` improvements ============================ The new function `scipy.special.log_expit` computes the logarithm of the logistic sigmoid function. The function is formulated to provide accurate results for large positive and negative inputs, so it avoids the problems that would occur in the naive implementation ``log(expit(x))``. A suite of five new functions for elliptic integrals: ``scipy.special.ellipr{c,d,f,g,j}``. These are the `Carlson symmetric elliptic integrals <https://dlmf.nist.gov/19.16>`_, which have computational advantages over the classical Legendre integrals. Previous versions included some elliptic integrals from the Cephes library (``scipy.special.ellip{k,km1,kinc,e,einc}``) but was missing the integral of third kind (Legendre's Pi), which can be evaluated using the new Carlson functions. The new Carlson elliptic integral functions can be evaluated in the complex plane, whereas the Cephes library's functions are only defined for real inputs. Several defects in `scipy.special.hyp2f1` have been corrected. Approximately correct values are now returned for ``z`` near ``exp(+-i*pi/3)``, fixing `8054 <https://github.com/scipy/scipy/issues/8054>`_. Evaluation for such ``z`` is now calculated through a series derived by `López and Temme (2013) <https://arxiv.org/abs/1306.2046>`_ that converges in these regions. In addition, degenerate cases with one or more of ``a``, ``b``, and/or ``c`` a non-positive integer are now handled in a manner consistent with `mpmath's hyp2f1 implementation <https://mpmath.org/doc/current/functions/hypergeometric.html>`_, which fixes `7340 <https://github.com/scipy/scipy/issues/7340>`_. These fixes were made as part of an effort to rewrite the Fortran 77 implementation of hyp2f1 in Cython piece by piece. This rewriting is now roughly 50% complete. `scipy.stats` improvements ========================== `scipy.stats.qmc.LatinHypercube` introduces two new optional keyword-only arguments, ``optimization`` and ``strength``. ``optimization`` is either ``None`` or ``random-cd``. In the latter, random permutations are performed to improve the centered discrepancy. ``strength`` is either 1 or 2. 1 corresponds to the classical LHS while 2 has better sub-projection properties. This construction is referred to as an orthogonal array based LHS of strength 2. In both cases, the output is still a LHS. `scipy.stats.qmc.Halton` is faster as the underlying Van der Corput sequence was ported to Cython. The ``alternative`` parameter was added to the ``kendalltau`` and ``somersd`` functions to allow one-sided hypothesis testing. Similarly, the masked versions of ``skewtest``, ``kurtosistest``, ``ttest_1samp``, ``ttest_ind``, and ``ttest_rel`` now also have an ``alternative`` parameter. Add `scipy.stats.gzscore` to calculate the geometrical z score. Random variate generators to sample from arbitrary univariate non-uniform continuous and discrete distributions have been added to the new `scipy.stats.sampling` submodule. Implementations of a C library `UNU.RAN <http://statmath.wu.ac.at/software/unuran/>`_ are used for performance. The generators added are: - TransformedDensityRejection - DiscreteAliasUrn - NumericalInversePolynomial - DiscreteGuideTable - SimpleRatioUniforms The ``binned_statistic`` set of functions now have improved performance for the ``std``, ``min``, ``max``, and ``median`` statistic calculations. ``somersd`` and ``_tau_b`` now have faster Pythran-based implementations. Some general efficiency improvements to handling of ``nan`` values in several ``stats`` functions. Added the Tukey-Kramer test as `scipy.stats.tukey_hsd`. Improved performance of `scipy.stats.argus` ``rvs`` method. Added the parameter ``keepdims`` to `scipy.stats.variation` and prevent the undesirable return of a masked array from the function in some cases. ``permutation_test`` performs an exact or randomized permutation test of a given statistic on provided data. Deprecated features --------------------- Clear split between public and private API ========================================== SciPy has always documented what its public API consisted of in :ref:`its API reference docs <scipy-api>`, however there never was a clear split between public and private namespaces in the code base. In this release, all namespaces that were private but happened to miss underscores in their names have been deprecated. These include (as examples, there are many more): - ``scipy.signal.spline`` - ``scipy.ndimage.filters`` - ``scipy.ndimage.fourier`` - ``scipy.ndimage.measurements`` - ``scipy.ndimage.morphology`` - ``scipy.ndimage.interpolation`` - ``scipy.sparse.linalg.solve`` - ``scipy.sparse.linalg.eigen`` - ``scipy.sparse.linalg.isolve`` All functions and other objects in these namespaces that were meant to be public are accessible from their respective public namespace (e.g. `scipy.signal`). The design principle is that any public object must be accessible from a single namespace only; there are a few exceptions, mostly for historical reasons (e.g., ``stats`` and ``stats.distributions`` overlap). For other libraries aiming to provide a SciPy-compatible API, it is now unambiguous what namespace structure to follow. See `gh-14360 <https://github.com/scipy/scipy/issues/14360>`_ for more details. Other deprecations -------------------- ``NumericalInverseHermite`` has been deprecated from `scipy.stats` and moved to the `scipy.stats.sampling` submodule. It now uses the C implementation of the UNU.RAN library so the result of methods like ``ppf`` may vary slightly. Parameter ``tol`` has been deprecated and renamed to ``u_resolution``. The parameter ``max_intervals`` has also been deprecated and will be removed in a future release of SciPy. Backwards incompatible changes ---------------------------------- - SciPy has raised the minimum compiler versions to GCC 6.3 on linux and VS2019 on windows. In particular, this means that SciPy may now use C99 and C++14 features. For more details see `here <https://docs.scipy.org/doc/scipy/reference/dev/toolchain.html>`_. - The result for empty bins for `scipy.stats.binned_statistic` with the builtin ``'std'`` metric is now ``nan``, for consistency with ``np.std``. - The function `scipy.spatial.distance.wminkowski` has been removed. To achieve the same results as before, please use the ``minkowski`` distance function with the (optional) ``w=`` keyword-argument for the given weight. Other changes --------------- Some Fortran 77 code was modernized to be compatible with NAG's nagfor Fortran compiler (see, e.g., `PR 13229 <https://github.com/scipy/scipy/pull/13229>`_). ``threadpoolctl`` may now be used by our test suite to substantially improve the efficiency of parallel test suite runs.

### 0.2.7 ``` ------------- Released on February 10th, 2022. - Dropped support for Py3.5 (due to the absence of manylinux wheel supporting both Py3.5 and Py3.10). - ``_BaseHMM`` has been promoted to public API and has been renamed to ``BaseHMM``. - MultinomialHMM no longer overwrites preset ``n_features``. - An implementation of the Forward-Backward algorithm based upon scaling is available by specifying ``implementation="scaling"`` when instantiating HMMs. In general, the scaling algorithm is more efficient than an implementation based upon logarithms. See `scripts/benchmark.py` for a comparison of the performance of the two implementations. - The *logprob* parameter to `.ConvergenceMonitor.report` has been renamed to *log_prob*. ```Links
