So I finally resolved in Ubuntu 20.04 it as below.

1. Main reason for my case was, I had broken pyqt5 - so I was not able to uninstall it and also NOT able to install a fresh version of PyQt5.

2. So finally had to manually delete PyQt5 + PyQt5-sip + PyQtWebEngine respective installed directories from the below three locations.

/usr/lib/python3/dist-packages

/usr/local/lib/python3.8/dist-packages

/home/user_name/.local/lib/python3.8/site-packages

3. Then install them back with pip install PyQt5 PyQtWebEngine PyQt5-sip

4. Now, check the installed versions of those packages by running pip freeze | grep -i pyqt

Now got the upgraded and correct package version as below

PyQt5==5.15.1
PyQt5-sip==12.8.1
PyQtWebEngine==5.15.1

5. Then also had to uninstall pandasgui by running pip uninstall pandasgui and then reinstall it again.

And now pandasgui is running fine.

Weird, looks like you don't have PyQt5-sip installed even though it says it's a dependency of PyQt5 which you do have. Maybe I'll explicitly add it to setup.py.

I noticed you posted a 2nd issue with a different error, does that mean you fixed this one?
