graph visualisation issues

[ppxasjsm]

Running the example script on the networkx2 branch I get the following error:

All dependencies were installed using conda, i.e.
conda install networkx
conda install graphviz
conda install pyQt=4

matplotlib version: '1.5.1'
networkx version: '2.2'
python version 3.5

Initialisation was done with:

db_mol = lomap.DBMolecules('path', parallel=12, display=True, output=True, verbose='info')

Thanks. Definitely some work to be done here. Unfortunately I don't have anyone in the group working on this right now, so it probably falls to me (which means it will take a while) unless @shuail or @nividic is in a position to help (but they have other jobs).

I found the issue.
It works fine with matplotlib version: '2.0', which I think would need to be a hard requirement.

Closing this; maintenance moved to github.com/OpenFreeEnergy/Lomap.
