However, this method is not applicable to all GNN operators available, in particular for operators in which message computation can not easily be decomposed, *e.g.* in attention-based GNNs. The selection of the optimal value of :obj:`decomposed_layers` depends both on the specific graph dataset and available hardware resources.
PyG provides the MessagePassing base class, which helps in creating such kinds of message passing graph neural networks by automatically taking care of message propagation. The user only has to define the functions ϕ , i.e. message (), and γ , i.e. update (), as well as the aggregation scheme to use, i.e. aggr="add", aggr="mean" or aggr="max".

07.08.2021 · In Pytorch Geometric, self.propagate will do the following: execute self.message, $\phi$: construct the message of node pairs (x_i, x_j) execute self.aggregate, $\square$, aggregate message from neigbors. Internally, the aggregate works like …
Aug 30, 2020 · Just getting started with Pytorch-geometric. Let’s say I have an undirected graph, with four nodes, each with a single feature, and I wish to implement the Graph Convolutional layer as shown in the documentation here: h…
r"""Computes or updates features for each edge in the graph. This function can take any argument as input which was initially passed. to :meth:`edge_updater`. Furthermore, tensors passed to :meth:`edge_updater` can be mapped to.
