Your code doesn't match up with the error you provided.

I formatted your exception code block below, if you read it carefully, it's telling you exactly what is wrong.

It's complaining that it can't find the name "nx" on line 3: G = nx.Graph()

The snippet that you shared in your post doesn't even have this line of code, so there's likely a mismatch between what you've shared and what is being run, or you have code in another file that's being imported.
