DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working

[The-Compiler]

In Python 3.7, importing ABCs directly from the collections module shows a
warning (and in Python 3.8 it will stop working) - see
python/cpython@c66f9f8

.../site-packages/pkg_resources/_vendor/pyparsing.py:943: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
  collections.MutableMapping.register(ParseResults)

.../site-packages/pkg_resources/_vendor/pyparsing.py:3226: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
  elif isinstance( exprs, collections.Iterable ):

I'd be happy to help with fixing this, but it looks like pyparsing.py is vendored from upstream - I'll open an issue there as well, but that project looks quite inactive...

[The-Compiler]

Ah, looks like there's https://sourceforge.net/p/pyparsing/bugs/106/ already (and pypa/pip#5013 too)

PyParsing has moved to GitHub. Here's a PR for it: pyparsing/pyparsing#16.

[tirkarthi]

PyParsing release with the fix : https://github.com/pyparsing/pyparsing/releases/tag/pyparsing_2.2.1

Thanks

[hugovk]

PyParsing has been updated to 2.2.1 in Setuptools in d4b5eb6.

This issue can be closed.

[jaraco]

Released in 40.4.1.

PyParsing has been updated to 2.2.1 in Setuptools in d4b5eb6.

This issue can be closed.

The version in _vendor directory is still 2.2.0 and I'm still getting the warning while using 40.4.2.

setuptools/pkg_resources/_vendor/pyparsing.py

Line 63 in 5ba6a42

__version__ = "2.2.0"

[5j9]

There are two copies of pyparsing.py in the repository. One in the pkg_resources/_vendor and one in setuptools/_vendor. Only the second one has been updated.

[jaraco]

:/

At one point, the setuptools package would re-use the vendored dependencies from the pkg_resources package. I suspect these were split as part of the effort to see pkg_resources split out as a separate package.

I think this was fixed in 2862b90.

[cepbrian]

Why am I still getting this warning? I'm using 2.10 and pyparsing 2.3.1

[pganssle]

@cepbrian What does "2.10" refer to there?

[cepbrian]

2.10 is the version of jinja2 I'm using.

> import jinja2
>> print (jinja2.__version__)
2.10

[tirkarthi]

jinja doesn't seem to be a part of setuptools. This warning was fixed in jinja's master branch but not released yet : pallets/jinja#867

[cepbrian]

It was fixed in October, but not released yet? Can we get it released?

[tirkarthi]

Please follow up with jinja project tracker since setuptools cannot do anything about the release timeline.

Thanks

I hope this issue has started again!

I have Scikit-learn & Pyparsing versions:
In [14]: pyparsing.__version__
Out[14]: '2.4.6'
sklearn.__version__
Out[19]: '0.19.1'

Should i rollback to pyparsing 2.2.1?

[The-Compiler]

@VikneshSK The beginning of that output shows that this is happening in scikit-learn, not in pyparsing and not in setuptools:

...\site-packages\sklearn\utils\__init__.py:4
...\site-packages\sklearn\model_selection_split.py:18

Looking at the git repository I can't find the code referenced in your warnings, so I'm guessing this has been fixed in newer versions.

[jaraco]

Locking this issue as Setuptools fails on warnings so can't have this issue. If you've encountered this issue, it's probably in a different project.
