update iris and ensure iris.tests is included #154

Closed alaniwi closed 6 years ago

alaniwi commented 6 years ago

Have been advised that filelock will be needed as a dependency.

If any problem providing latest Iris, still provide filelock.

Per https://ncas-talk.slack.com/archives/C0Q66PALA/p1515768976000140

Built filelock. Does what it should do with simple test code:

import time
from filelock import FileLock

lock = FileLock("/tmp/my.lock")

with lock:
    print "start"
    time.sleep(5)
    print "end"

(running more than one instance simultaneously)

Build dask (new dependency).

Not building pep8 (optional dependency), because this is now replaced by pycodestyle, and it appears that Iris will be migrating to it (per https://github.com/SciTools/iris/issues/2941). Built pycodestyle but not added as a dependency yet.

Updated setuptools as required.

Clean build and import of iris 2.0.0. No special action required to provide iris.tests (although on import, a warning about SSL in old python). But trying testing iris.load shows that dask is missing toolz dependency.

alaniwi commented 6 years ago

Raised an issue at https://github.com/SciTools/iris/issues/2994 regarding documenting toolz as an explicit dependency of iris (because it is only an "extras" dependency of dask). Nonetheless, rebuilt dask including most of the optional dependencies (all except distributed, which has a bunch of other dependencies including an apparent cyclic dependency on dask).

With this done, opening a netCDF file in Iris and extracting some data and metadata seemed to work fine.

Running a python script trying to import iris I get an error message: 'Ambiguous 'iris' package' and details the three options, but I'm not sure how to get it to know I want the scitools one? Thanks for suggestions.

Same problem. Downloaded iris from conda-forge and it is iris 2.1.1 same error message. Downgraded to 2.1.0 still same error message when import iris
