MPL 3.9.1 on windows has been removed from PyPI: matplotlib/matplotlib#28551

[tacaswell]

The 3.9.1 wheels on windows would, depending on import order, cause segfaults, see matplotlib/matplotlib#28551 (comment).

We deleted the bad wheels to avoid segfaults (which seemed like a good idea) but failed to anticipate that this would cause downstream projects to start trying to build mpl from source instead of pulling the 3.9.0 wheel. We have now yanked the whole 3.9.1 release to fix these problems and will get 3.9.2 out as quick as we can.

To prevent this sort of thing in the future (trying to build something from source when you are not prepared to do so) I suggest using matplotlib --only-binary "matplotlib" in your requirements file (which may be a good practice for all wheels that have extensions).

Sorry for the trouble.
