WebPyTorch deposits the gradients of the loss w.r.t. each parameter. Once we have our gradients, we call optimizer.step () to adjust the parameters by the gradients collected in the backward pass. Full Implementation We define train_loop that loops over our optimization code, and test_loop that evaluates the model’s performance against our test data.

Several popular graph neural network methods have been implemented using PyG and you can play around with the code using built-in datasets or create your own dataset.
WebThe graph classification can be proceeded as follows: From a batch of graphs, we first perform message passing/graph convolution for nodes to “communicate” with others. After message passing, we compute a tensor for graph representation from node (and edge) attributes. This step may be called “readout/aggregation” interchangeably.
