Re: [igraph] Loading graphs into python-igraph

Please try to replace commas in your file with spaces. When reading  
directly from a file, igraph uses the routines of the C core and it  
expects whitespace between vertex indices. If igraph still does not  
recognise the file format, you can also try to force it to use the  
edgelist reader:

graph = igraph.load('testfile', format='edgelist')
