undefined symbol: qt_version_tag

Hello,
I've install PyQt5 via pip, into a conda env, which worked fine but then when I try to import PyQt5.QtWidgets I always get:

ImportError: /home/ben/Softwares/miniconda3/envs/cp_test/lib/python3.8/site-packages/PyQt5/QtWidgets.abi3.so: undefined symbol: qt_version_tag, version Qt_5.15

I run the env in Ubuntu 22.04.2LTS, if that can help and here is the env related pkgs:

Successfully installed markdown-3.4.3 qtwidgets-1.1

Thanks in advance for the help.

Hi and welcome to devnet,

You should test the conda version of PyQt5.

Otherwise, I would recommend that you contest the authors of PyQt to see if they are aware of that issue.
