Nov 12, 2020 · I am wondering if the GCNConv (and other modules in pytorch_geometric) support taking batch inputs? Specifically, my inputs are of the following dimensions: x = (batch_size, num_of_nodes, node_features) edge_index = (batch_size, 2, num_of_edges)

An extension of the torch.nn.Sequential container in order to define a sequential GNN model. Since GNN operators take in multiple input arguments, torch_geometric.nn.Sequential expects both global input arguments, and function header definitions of individual operators.

27.08.2020 · Okay so the problem definitely comes from your graphs, not from your network. In the GCNConv, at some point scatter_addwill create a tensor out with a dimension of length edge_index.max()+1(i.e 541691).Then it will iterate simultaneously over this tensor and x (of size [678,43]). So there's an obvious problem in your graph : your edges are indexing vertices that do …
