Unweighted node2vec not possible?

[georgeblck]

Thank you for this package; it made applying the node2vec algorithm much easier in python.

I have a directed but unweighted graph and used the is_weighted=False flag in the node2vec function. The internal node2vec output still showed Graph is weighted. (-w)=YES which made me look into your source code and if I understand correctly, the is_weighted flag is always ignored?

It was easy to change it in the source code, so I don't care too much. I was just wondering if there was a reason for this?
