Error with PySide6 when using matplotlib: Failed to enable GUI event loop integration for 'qt'

[MarcosCalvi]

Hello, I am having this problem when I try to debug an app using PySide6 and matplotlib, it uses some graphs and seems to be the part that goes wrong.

This is the output in the console:

Failed to enable GUI event loop integration for 'qt'

Backend QtAgg is interactive backend. Turning interactive mode on.

I am using PySide6 and I think the qt_loaders is what is missing Qt6.

Any help?

The debugger doesn't support Qt6 at the moment - see #1112

(You can still debug, but none of the special integration features are expected to work.)
