Code Snippet

import matplotlib.pyplot as plt

plt.style.use("default")

def myplot(ax: plt.Axes):
    ...

Repro Steps

With above code, it shows '"style" is not a known member of module' and '"Axes" is not a known member of module'.

It just works yesterday, so I installed pylance extension v2022.8.40, works fine.

thanks the issue.
We recently updated our matplot stubs from here https://github.com/Microsoft/python-type-stubs

I'll take a look

[bschnurr]

right click 'plt' and choose 'go to declaration'

add

from matplotlib import style as style

to vscode-pylance/dist/bundled/stubs/matplotlib/pyplot.pyi as a workaround for now

That works, thank you!

I also changed from .axes import Axes to from .axes import Axes as Axes and fixed the issue about Axes.
