[igraph] python.exe stop working!

[address@hidden]

    

        I want to use the data provided by Stanford(http://snap.stanford.edu/data/com-Friendster.html) which contains 65608366 nodes.When reading in the edges file of the graph,it report "python.exe stop working".Is it because that the data size is too huge?My computer RAM(128G) is encough.

the code is :
                    import igraph as ig

                    dirG=ig.Graph.Read_Ncol('./community_data/com-friendster.ungraph_new.txt')
