Test PySide6 and PyQt6

See original GitHub issue

If these latests versions work (hopefully also with QtPy), we should make them our default recommendations (in etc). Once Matplotlib support is out, it might also be worth considering supporting only PySide6 in the future for the following reasons:

  • PySide6 is the officially supported Qt bindings package for Python, which has received continuous updates
  • PySide6 provides binary wheels on PyPI for Windows, macOS (no ARM64 at the moment though), and Linux
  • PySide6 is licensed under the LGPL, which is potentially less problematic when used with BSD- or MIT-licensed code (PyQt5 is GPL or commercial only)

Potential blockers (in descending severity):

  • Matplotlib support is required (
  • Anaconda/Conda-Forge packages might not be available for a long time (they are still stuck at Qt 5.12 from end of 2018 because upgrading to even 5.15 seems to be problematic)
  • macOS ARM64 wheels are currently not available

Also, since MNELAB depends on Matplotlib we need to wait for to get merged upstream.
