Multiple metapaths

[xwxahu]

Hi! Very thanks for your codes and data.Howerever, I have a problem of multiple metapaths. The HIN usually contains more types of nodes and what should I do to get each node type embedding? For example, author (A)、 paper (P) and conference (C) are all in the DBLP dataset. I have a try to list them to one edge_list file as following:
1 A 2 P A-P
2 P 3 C P-C
But the program is in an endless loop. Could you tell me how to process this type of dataset? Much thanks for you.
