Multi-graph !

[MehdiZouitine]

Hello to all! Thank you for this beautiful library.
I would like to create a multi graph with only 1 type of node but several types of relationship. With the heterogeneous graph framework, we are obliged to declare several types of nodes.

Is it possible to create a graph with only one type of node but several types of edges (a multigraph)?

Thank you in advance!

You can either use HeteroData as well for this, or make use of an edge_type vector along your edge_index and use layers such as RGCNConv to process.
