Part of metadata file is deprecated

[BKaraargirov]

Description

The METADATA generated by setup.py has deprecated REQUIRES fields example from 0.18.3:

Requires: numpy (>= 1.16.5)
Requires: scipy (>= 1.0.1)
Requires: matplotlib (>= 2.0.0,!=3.0.0)
Requires: networkx (>= 2.0)
Requires: pillow (>= 4.3.0,!=7.1.0,!=7.1.1)
Requires: imageio (>= 2.3.0)
Requires: tifffile (>= 2019.7.26)
Requires: PyWavelets (>= 1.1.1)
Requires-Python: >=3.7
Description-Content-Type: text/markdown
Requires-Dist: numpy (>=1.16.5)
Requires-Dist: scipy (>=1.0.1)
Requires-Dist: matplotlib (!=3.0.0,>=2.0.0)
Requires-Dist: networkx (>=2.0)
Requires-Dist: pillow (!=7.1.0,!=7.1.1,>=4.3.0)
Requires-Dist: imageio (>=2.3.0)
Requires-Dist: tifffile (>=2019.7.26)

This causes a warning in tools such as PEX:

PEXWarning: Ignoring 8 `Requires` fields in scikit-image 0.18.3 metadata:
1.) Requires: numpy (>= 1.16.5)
2.) Requires: scipy (>= 1.0.1)
3.) Requires: matplotlib (>= 2.0.0,!=3.0.0)
4.) Requires: networkx (>= 2.0)
5.) Requires: pillow (>= 4.3.0,!=7.1.0,!=7.1.1)
6.) Requires: imageio (>= 2.3.0)
7.) Requires: tifffile (>= 2019.7.26)
8.) Requires: PyWavelets (>= 1.1.1)

You may have issues using the 'scikit-image' distribution as a result.

Seeing as there is both requires and requires-dist(which is supposed to be used from metadata v1.2 onward ) is there still need to have both ?

I think this happens because both requires and install_requires parameters are used:

scikit-image/setup.py

Line 243 in b566789

install_requires=INSTALL_REQUIRES,

Thanks for reporting this. If you want to play around and see what fixes it locally, that would be helpful. Otherwise, we will try to take a look soon
