etypes_lists is used for the relational rotation metapath instance encoder, which is inspired by the RotatE knowledge graph embedding model. If a relation is symmetric (like the user-user friend relation in Last.fm), then the relation vector between them should contain only 1 or -1. I think 1 would be appropriate, then this just means I don’t need to have relation vectors to do any complex space rotation. So I use None here to indicate symmetric relation (edge type).

Thanks, I may need to get a better understanding of the RotatE knowledge graph embedding model.
