Remove Feature from setup.py

[sikuan]

Hi,

from setuptools 46.0, Feature support was completely removed: pypa/setuptools@c719690 and pypa/setuptools#1979.

There are some Feature usages in this module:

openslide-python/setup.py

Line 2 in 8e2c948

from setuptools import setup, Extension, Feature

openslide-python/setup.py

Line 19 in 8e2c948

'performance': Feature(

So suppose these should be removed. Thanks.

Dear everyone, as a gesture of courtesy towards the community, we forked the openslide-python repo and we released it on PyPI. Please note that this is a temporary workaround to have openslide-python installable via pip without the setuptools issue.

I made a patch in a repository I cloned manually, before realizing that there was already an openslide-python repo on github.
PiRK/openslide@c11b26a

It works for me, but I don't really understand what Feature was used for. I hope my change didn't break anything else.

Should I try to submit a pull request with my patch?

I think this is what was causing me to get the ImportError: cannot import name 'Feature' from 'setuptools' error when installing openslide-python.
Obviously not a permanent fix but downgrading the setuptools to 45 will let you install openslide-python:
pip install setuptools==45

Hello friends! I have a colleague who ran into the same set of issues here. I do see that the source code on the latest master branch is up-to-date, and doesn't use Feature in setup.py. Would there be a possibility of cutting a patch release on PyPI, to make installation easier for all users please? tagging @hugovk and @bgilbert, who are (I think) the biggest code contributors here. Given that the package is up on PyPI, I hope it won't be too big of a burden for you two!

Hello! I'm just an occasional contributor and don't have merge or release rights for this repo.

@bgilbert is listed as maintainer on https://pypi.org/project/openslide-python/ and hopefully can make a release soon!

[paul-english]

This is pretty old for a really minor issue that totally blocks most new installs. @bgilbert can we get a release to fix this, or add more maintainers to this repo?

[bgilbert]

Yup, we'll get a new release out soon.

OpenSlide Python 1.1.2 has been released with a fix for this issue. Thanks for your patience and persistence, all.
