PyG (PyTorch Geometric) is a library built upon PyTorch to easily write and train Graph Neural Networks (GNNs) for a wide range of applications related to structured data. It consists of various methods for deep learning on graphs and other irregular structures, also known as geometric deep learning, from a variety of published papers.

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".
Since GNN operators take in multiple input arguments, torch_geometric.nn.Sequential expects both global input arguments, and function header definitions of individual operators. If omitted, an intermediate module will operate on the output of its preceding module:
