Do I need to specify the full incidence matrix for HypergraphConv to work? #740

Hello! I'm trying to use HypergraphConv with hypergraphs of varying sizes, therefore I need the weight matrix to be independent of the number of vertices. How can I achieve this?

As far as I see, there is nothing that prevents you from using the HypergraphConv with hypergraphs of varying sizes. The parameters do not dependent on the number of vertices. You can even encode multiple hypergraphs in hyperedge_index by stacking them to the diagonal form (N_1 + N_2 + ...) x (M_1 + M_2 + ...).
