Networkx read_gml error "networkx.exception.NetworkXError: cannot tokenize u'graph 'in (3, 1)"

I try to use networkx to read in a gml file (quite simple?), Except whenever I try to read in a file, I get the error "networkx.exception.NetworkXError: cannot tokenize u'graph" at (3, 1) "I am not too familiar with gml or networkx, so I myself could not diagnose the problem.

What is even more strange, since my colleague will execute the same command with the same file, and it will execute without errors. I uninstalled and reinstalled networkx several times at this point, can anyone help to determine what the error might come from?

import networkx as nx g = nx.read_gml('disciplineNetwork.gml')

Traceback (last last call):

File "", line 2, in read_gml

I had the same problem and the solution for me was downgrading networkx.

Yes. A good solution for switching to a network solution 1.9.1. You can download networkx 1.9.1 at https://pypi.python.org/pypi/networkx/1.9.1 . Download the zip file. Then use: pip install networkx-1.9.1.zip. This will automatically remove networkx 1.10 and replace it with networkx 1.9.1.

I'm not sure about the format of your gml file, but reformatting your gml file may solve your problem.
