TypeError: '>' not supported between instances of 'NoneType' and 'sys.version_info'

[karrmagadgeteer2]

A bit of a newbie so I am not sure if this is appropriate here or for the statsmodels package. The below error shows on Python 3.11 but not Python 3.10. The test suite is run with Github workflows on ubuntu-latest, windows-latest and macos-latest with the same outcome.

Hi @karrmagadgeteer2 ! This has already been patched in version 0.5.3. Please let me know if things don't work for you after updating; but until then I'll close this one out.

Thanks for taking the time to make our software better!

Should this be fixed @matthewwardrop ? I was just running some old code on a new computer, found I didn't have plydata installed, did a fresh pip install plydata, but still get this error.

@jwhendy Apologies for the necrobump, but this package is patsy, not plydata. Hopefully this is resolved for you!

[jwhendy]

@matthewwardrop that is... pretty hilarious. 🤦 Signs of a desperate data scientist on a deadline grasping at the internet for hope. Thanks for letting me know, and I'm sure I did resolve somehow or another!
