How to update stubs ?

[Erhie]

Please tell me, how to update stubs in .pyi files.

I have a problem with the modul Piilow.

The code in Image .pyi has the prototype
def fromarray(obj, mode: _Mode | None = ...) -> Image: ...
and _Mode is defined as
_Mode = Literal["1", "CMYK", "F", "HSV", "I", "L", "LAB", "P", "RGB", "RGBA", "RGBX", "YCbCr"]
But the function fromarray awaits the type str for mode.

Thank you for your answer

These stubs are from typeshed: https://github.com/python/typeshed

IIRC the intent is that these are the only valid inputs to mode-like parameters, hence it being a literal set of values. Having written a good bulk of PIL stubs, they do document a specific list of values.

If you think that the types are wrong, I would suggest filing an issue on typeshed to discuss it.

Now I had success by uninstall and newly installed Pillow and
purge in ....vscode\extensions\ms-python.vscode-pylance-2021.9.1\dist\typeshed-fallback\stubs\Pillow
and now there is no warning for this issue.
