LGTM!

Should we also add a condition on the upper ray bound here?

modin/modin/config/envvars.py

Line 94 in ba2b6ea

if version.parse(ray.__version__) < MIN_RAY_VERSION:

@YarShev yes, done.

Is this superseded by #4568 ?

[devin-petersohn]

@mvashishtha doc build is failing because changes here are not compatible with docs/requirements-doc.txt. For some reason that is installing from the github.

[devin-petersohn]

This probably needs to change:

modin/docs/requirements-doc.txt

Line 12 in d5ff94e

git+https://github.com/modin-project/modin.git@master#egg=modin[all]

git+https://github.com/modin-project/modin.git@master#egg=modin[all]

@devin-petersohn I saw that failure, but what should we change it to? How can we install modin using requirements from the current PR?

[devin-petersohn]

@mvashishtha will you delete that line and see if that fixes it?

@devin-petersohn that didn't work either. "Build docs" gives No module named 'ray' as here. It doesn't look like I can pip install ../.[all] either. I'm trying to pin ray within the doc requirements.
