WebJan 25, 2024 · The return type of dgl.batch is still a graph (similar to the fact that a batch of tensors is still a tensor). This means that any code that works for one graph immediately works for a batch of graphs. More importantly, since DGL processes messages on all nodes and edges in parallel, this greatly improves efficiency.
