I do not think this PR fixes the problem, after applying the changes, now exception is thrown on Line 185

line 185, in _get_required_interactive_framework
    if not hasattr(backend_mod.FigureCanvas, "required_interactive_framework"):
AttributeError: module 'backend_interagg' has no attribute 'FigureCanvas'. Did you mean: 'FigureCanvasAgg'?

TLCFEM · 2022-09-16T21:55:45Z

One more check needs to be added:

def _get_required_interactive_framework(backend_mod):
    if not hasattr(backend_mod, 'FigureCanvas') or not hasattr(backend_mod.FigureCanvas, "required_interactive_framework"):
        _api.warn_deprecated(
            "3.6", name="Support for FigureCanvases without a "
            "required_interactive_framework attribute")
        return None
    # Inline this once the deprecation elapses.
    return backend_mod.FigureCanvas.required_interactive_framework

QuLogic · 2022-09-17T00:39:24Z

I don't believe the latter check was implemented.

No, it's not.

HarmvandenBrand · 2022-09-22T15:48:21Z

Can confirm this is still an issue with matplotlib 3.6.0 on python 3.10 in PyCharm 2022.2.2

Fixes matplotlib#23911.

Problem still occurring in PyCharm for me. Still requires FigureCanvas on backend module, running matplotlib 3.8.1. See line 342 of pyplot.py

ksunden · 2023-11-08T22:59:55Z

Not having a FigureCanvas class as a backend was deprecated in mpl 3.6 and expired in 3.8, it looks like the most recent versions of PyCharm do have it, so perhaps you need to update?

QuLogic · 2023-11-08T23:01:09Z

AFAICT, JetBrains added those values over a year ago, but I cannot tell from the tags exactly what version that means.

mposter1 · 2023-11-09T04:41:54Z

Update fixed. Thanks.

benyoung-libenyang · 2023-11-10T01:33:56Z

maybe you cloud try.
