Re: [igraph] ID's for nodes/vertices

[Håvard Wahl Kongsgård]

Also with the correct code for "similarity inverse log weighted"

a = i.similarity_inverse_log_weighted(vertices=33,23)

I again get the memory error

MemoryError: Error at vector.pmt:125: cannot init vector, Out of memory


Again python does not consume any memory.

Does this function also convert the graph into a matrix like object?
