When I start Memgraph I can't access query modules. Right after the startup, I get ImportError for the NetworkX module. I've checked and I can see that I have NetworkX installed. I've also tried to reinstall Mmegraph but I had no luck. The error is still there.
This is most likely due to the Python version. Memgraph is using the default system Python.
Check the Python version with python --version. If you don't run Python 3, upgrade it. With python3 there shouldn't be such problems.
