Additional context
Quick search on the web shows similar problems with TensorFlow (and related libraries) all over the place. However, TF seems alone seems to work fine for me (no errors). Here you can see the links to related problems:

I tried the solutions provided in all of the above (basically reinstalling everything multiple times with different version combinations) but none worked for me.
