WebGATConv can be applied on homogeneous graph and unidirectional bipartite graph . If the layer is to be applied to a unidirectional bipartite graph, in_feats specifies the input feature size on both the source and destination nodes. If a scalar is given, the source and destination node feature size would take the same value.
