[IronPython] Cannot import 'Networkx' into Ironpython

[Jeff Hardy]

It looks like networkx is a pure-Python package, so it should work.
What are you adding sys.path? I cloned the repo into the networkx
folder, which contains a networkx folder - sys.path should point to
the outer folder.

>>> sys.path.append(r'C:\Users\<user>\Documents\Repositories\networkx')

Doing that, it complains that it can't find subprocess, which is a bug
in the alpha - I'm not sure it's fixed in B1, but it will be in B2. In
the meantime you can copy subprocess.py from
https://github.com/IronLanguages/main/blob/master/External.LCA_RESTRICTED/Languages/IronPython/27/Lib/subprocess.py
into the Lib folder for your IronPython installation.
