Thanks for your reply!
Could you please share an example for dgl heterograph with multiple edge types ( or relations), and edge attributes. I created my hetero graph via torch geometric but I did not find similar example in dgl (more about defining/adding edge features in multi relational graph).
Regarding RGCN for heterogeneous or homogeneous, I am not sure about performance of model when we are using homogeneous graph with multi dimensional edge features instead of heterogeneous graph with multiple edge types (relations). It would be nice if you could share more information/works about it.
Thank you in advance!
