Solved Any access to QtCore through PySide2 causes errors with autocomplete, help(QtCore) causes fatal python error then crashes python
-
Hi all,
this is my first time posting so go easy on me. Ive been using Qt for Python on and off for a few years however this is the first time I've had issues with QtCore.
I'm using Python with windows 10: installed everything below from executable or through Pip
Python: 3.8.2
PySide2: v5.14
PyQt5: v5.14
Eclipse IDE with PyDevI am able to import from PySide2 any module required, and at runtime everything is per normal.
However in my IDE the QtCore import throws a warning displaying "Unresolved Import:Qt, Slot etc etc" This is more of an annoyance than anything as it highlights half of my code with errors. I'm also unable to access the autocomplete for anything QtCore related.
Things I've tried prior to asking for help:
-
uninstalled all other python versions to be sure it was grabbing the correct PySide2
-
updated PySide2 with pip yesterday
-
Installed PyQt5 to check QtCore there and that imports as expected with none of these issues described in this post.

I thought maybe it was an issue with my IDE so I ran Python 3.8.2 from CMD and attempted the import from there. A request for help(module) returns expected for all modules except QtCore where it gives me this error:

I thought maybe its an administrator restriction however running Python with administrator rights turned no results either.
Any help would be greatly appreciated

Cheers for the reply Denni,
I'll look through the bug reports for PySide2 and see if there's any mention of the above issue. A lot of the bugs there go over my head. Continuing with PyQt5 for now.
Will report back with an answer if I find one.

Bug fixed PYSIDE-1272
This will be included in 5.14.2.2 and 5.15I rolled back my PySide2 version to 5.14.1 where this was still working.
