Have you check? please let me know. please create any pyqt5 project and import PySide2extn. and see if it shows any error.

Solution:
This is usually because there are multiple versions of the QT shared libraries on the system which are incompatible with each other. For instance, if an application installed from apt required Qt5, ubuntu would store the QT shared libraries in:
/usr/lib/x86_64-linux-gnu/
Meanwhile, the PyPI installed PyQt5 stores QT shared libraries in:
/lib/python/site-packages/PyQt5/Qt5/lib

The easiest solution to the import error is to ensure that ubuntu only finds PyPI’s shared QT5 libraries by modifying the system environment variable LD_LIBRARY_PATH.
