I have just upgrade my ubuntu. I have this error on spyder:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

  scaled(self, QSize, aspectRatioMode: Qt.AspectRatioMode = Qt.IgnoreAspectRatio, transformMode: Qt.TransformationMode = Qt.FastTransformation): argument 1 has unexpected type 'float'

All the solution that I have found deal with specific application developed my different user and not for probel related to upgrade or ubuntu.

CodePudding user response：

Same problem here!! Everything is updated to the latest version Unbuntu, pytq5 ,etc...

CodePudding user response：

I had the exact same problem, did a search with the following two items :

"spyder" "mainwindow.py, line 3624" # aka a piece of the error message

I found the bug report #16571 on spyder's github : "TypeError in Tour with Python 3.10", which identified python 3.10 as the culprit.

In Debian aptitude I downgraded python 3 from 3.10 to the 3.9 version, launched Spyder again and...problem solved !
