mypy: python 3.10+ - Githubissues

oliver-sanders commented 11 months ago

Mypy appears to be raising false positives in imported code for Python 3.10+, so currently, we're only running it for Python 3.9.

We will need to address this going forward.

The problem:

Matplotlib has dropped Python 3.7 support in their latest releases.
MyPy is complaining for non 3.7 compatible syntax in the non 3.7 compatible matplotlib code.
But these non compatible versions shouldn't get installed for 3.7 anyway (the install tool should handle this).
Adding an upper pin for Matplotlib which only applies to Python 3.7 doesn't make this go away.

Because no_silence_site_packages=false (the default) I wouldn't expect any errors from imported code anyway?

I don't think we can do anything about this

Ok, I guess we'll stick with 3.9 for linting until we are able to drop 3.7 support. Bit of a pain for development, but easy to achieve in CI.
