How to load movie-lens10M

[Cung806]

the movie-lens 10M data form is not adjlist or two rows(id1,id2). I do not understand how to transfer movie-lens to adjlist. May be the node is userid and the other node is movie id ?? but different user and movie may own same id.I'm confused.
I'm hoping for your reply .Thanks a lot.

one option (the one I used) is to start the ids of the movies just after the ids of the users. Concretely, you sum to the movie ids the number of unique users. In general, find whatever way to give different user and movie a unique id. I hope this helps.
