[Bug]: import matplotlib.backends.backend_qt5agg error for pyside6 · Issue #24212 · matplotlib/matplotlib · GitHub

Bug summary

matplotlib/lib/matplotlib/backends/qt_compat.py

Line 144 in 318b234

_to_int = operator.attrgetter("value") if QT_API == "PyQt6" else int

Have to check for "PySide6" too.

Code for reproduction

$ QT_API=pyside6 python -c "import matplotlib.backends.backend_qt5agg"

Yes it is fixed already. Can't reproduce the issue with main branch.

$ pip freeze
matplotlib @ git+https://github.com/matplotlib/matplotlib.git@80b15fb17be6455680a4830d0644731f8ee6bb8b
PySide6==6.4.0

For me works fine.

Was fixed in #24158
