Hi there!
I just started using the Python igraph module. The online documentation says: "When a graph is indexed by a pair of vertex indices or names, the graph itself is treated as an adjacency matrix and the corresponding cell of the matrix is returned" Unfortunately, when I try this out, I get an error: >>> from igraph import * >>> net = Graph.Erdos_Renyi(100, p = 0.05, directed=True) >>> net[1,2] Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError: 'Attribute does not exist' Is this a bug or is something wrong? I'm using Python 2.7.3 on Ubuntu Linux 12.10 64-bit. I've installed igraph from the standard package repository. All help is appreciated. Best, Cedric
