That's correct - currently GraphFrame does not compute PageRank with weighted edges.

To: user >
Hi guys,
I am trying to compute the pagerank for the locations in the following dummy dataframe,
src des shared_gas_stations
A B 2
A C 10
C E 3
D E 12
E G 5
...
I have tried the function graphframe.pageRank(resetProbability=0.01, maxIter=20) in GraphFrame but it seems like this function doesn't take weighted edges. Maybe I am not using it correctly. How can I pass the weighted edges to this function? Also I am not sure if this function works for the undirected graph.
Thanks a lot!
