I had this problem in ubuntu20.04 in jupyterlab in my virtual env kernel with python3.8 and tensorflow 2.2.0. Error message was

ImportError: No module named enum

problem was that in symbolic link in /usr/bin/python was pointing to python2. Solution:

cd /usr/bin/
sudo ln -sf python3 python

Hopefully Python 2 usage will drop off completely soon.
