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. :)
