RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

I have downloaded the 20.04 version and I got the same undefined symbol error. I then removed PyQt and qt5 and reinstalled and now I get:

from PyQt5 import QtCore, QtWebEngineWidgets
ImportError: /lib/x86_64-linux-gnu/libgssapi_krb5.so.2: undefined symbol: krb5_ser_context_init, version krb5_3_MIT

I’ll have a bit more of a look into it but if anyone has any ideas that would be great
