Import Error: can't import name gcd from fractions

[444thLiao]

Since the script "Network_generator.py" doesn't import fractions or gcd directly, it might be caused by some inter-packages conflicts.
I think it would be easier to trace the error by uploading a screenshot or the full text reported by the python. It would tell us which line this error was raised at.

Sorry, since the server is one-way, I can't export to copy the error report file, so I screenshot them.

That's ok. A Screenshot is enough.

So the problem actually is caused by the conflicts between networkx and python3.9.
In general, update/downgrade either one is ok to solve the problem as the links said. But the fixed version of networkx is because updating the networkx would raise another error during the network visualization.

Thus, I think it's better to use python3.8 and install related packages as the requirement said would be fine.

I have tested it with python3.8. The gcd function has not yet moved to the math package. So it would be fine in this step.

I create a new environment with python3.8 using conda, and re-install tmap2.
And the bug turns to be solved!

Thanks for your advice, enjoy your weekend!
