Re: [igraph] Loading graphs into python-igraph

[Eric Sun]

Thanks Tamas, format=’edgelist’ solved the problem.

Another thing I’m wondering about:  is there any way to load a graph in Python-igraph that’s not in an external file?
Igraph.load() and Graph.Read() seem to only be able to support an external file.

Is there any way to load a series of edgelists that’s stored as a Python array (or some other Python data structure), other than dumping it to a file and reading it back in again?

Thanks,
Eric
