[...] I have now just added a Graph.add_edge_list() to the git version, which takes a list of edges to be added, which can be a numpy array. If you have a full adjacency matrix instead of an edge list, you can do simply:

g.add_edge_list(transpose(nonzero(a)))

This should be much faster than the Python loop above.

This is really great, I will try the git version as soon as possible. Thank you very much. Pietro
