Re: [igraph] Memory error

[Ronquillo, Edgar Nahum]

I first populate a list of tuples which represent all the edges. At the same 
time I populate a list with the weights for those edges. All this information 
comes from a big text file. After they are populated I do the following:

G.add_edges(listEdges) #ERROR IS PRODUCED HERE
G.es["weight"] = listCosts
 print G.get_shortest_paths('20000', '90000', weights='weight')

Sorry I am not allowed to display any more code. But what I just explained is 
exactly what I am doing.

I don't know, I don't know what you are doing.

I don't know how to put this without just repeating myself, but please show us 
what you are doing, otherwise we can't help you. :)
