Connection between smop and networkx - different errors depending on versions of networkx

I am new to python, and I found a matlab code online that I want to convert to python code using smop. I've installed smop, however when I try to run it I get an error.

When I have networkx version 1.11 I get the following error trying to run smop main.m

    Traceback (most recent call last):
  File "C:\Users\IDABUK\Anaconda3\envs\smop\lib\site-packages\smop\main.py", line 66, in main
    G = resolve.resolve(stmt_list)
  File "C:\Users\IDABUK\Anaconda3\envs\smop\lib\site-packages\smop\resolve.py", line 54, in resolve
    u = G.node[n]["ident"]
AttributeError: 'DiGraph' object has no attribute 'node'
Errors: 1

When I install a later version of networkx (pip install networkx==2.0 or pip install networkx==2.5) I get the following error:

    Traceback (most recent call last):

ImportError: cannot import name 'gcd' from 'fractions' (C:\Users\IDABUK\Anaconda3\lib\fractions.py)

I am running this from the anaconda prompt window (anaconda power shell?).

Is there a way to fix this? The only solutions I find online are people installing various networkx-versions which does not seem like a solution for me in this case, or changing 'node' to 'nodes' directly in the code, however I can't find any instances of 'nodes' in the matlab code.
