I am trying to update spyder on rawhide and F35. The main issue I have is
that pyqt requirements are strict. From the setup file,

Fedora has 5.15.x. If I relax QT versions, built and launch spyder, I get
this error and spyder fails to launch.

Do you know where is this error triggered? Try explicitly converting the
floats to integers.
Yeah, that sounds more like a common Python 3.10 issue than an issue with
newer PyQt.
No, this is definitely a change in PyQt, or at least sip, cf.

The fix is 'easy', but you need to find everywhere that might trigger
it. QSize takes an int now, as it does in Qt (from C++), instead of
coercing a float.
Python 3.10 also contains a change where you can no longer pass floats to
extension modules in cases where there would a loss of precision (e.g., as
an int).
