Re: [igraph] community clustering in python

[Tamas Nepusz]

Hi,

Have you tried simplifying the graph before starting the community  
detection? Our former implementation did not work for graphs with  
multiple or loop edges. This was corrected recently in the dev branch  
and will be released officially as igraph 0.5 in a couple of weeks  
(possibly :)). So my suggestion is:

G.to_undirected()
G.simplify()
Lsv = G.community_fastgreedy()

> Should i just be using/learning R?
I think the error exists in the R interface as well, since they both  
use the common C core.
