Other information

[phlax]

not sure why this wont let me set newer setuptools - versions available only seem to go to 44.1

[aaliddell]

Version 44 was the last to support both Python 2 & 3. So until rules_python fully drops Python 2 support, it may be stuck with this version.

does that also preclude this change ?

[aaliddell]

Perhaps, but I think the new pip_install is only intended to support Python 3 (#409). The issue seems to be that there's also the older packaging rules still present, which support Python 2.

it would be really helpful if this were included from our pov, but my bazel knowledge is a bit limited so im not totally sure of the effect

I personally think this will work itself out and be easier to manage once the other train of PRs is merged as mentioned here #421 (comment)

In summary:

• Maintainers to cut new release that will be the last release with any semblance of Python 2.7 and 3.5 support for pip_install (it was never really supported, but kinda worked sometimes).
• Remove Python 3.5 support from CI Removes Ubuntu 16.04 (and Python 3.5) support from CI #417
• Upgrade to pip 21.0.1 (pip dropping Python 2.7 and this adds support for Big Sur and Apple Silicon wheels. The setuptools upgrade could possibly be added here tbh, since setuptools > 45 requires Python > 3.5. pip: 20.3.4 -> 21.0.1 #412

This change can't really be done until the above is done. It might also be possible to include this as part of #412, but perhaps also as a fast-follow too, since it is an unrelated changed to #412.
