I’m trying to port this to Python, but not having much success:
>>> graph = igraph.load('testfile')
IOError: unknown file format: None
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')
