PyTorch Geometric (PyG)

Routing Boundary

Use this skill only for PyTorch Geometric, torch_geometric, PyG, graph neural networks, GCN/GAT, graph classification, node classification, link prediction, and heterogeneous graph learning. Do not use it for generic neural networks, CNN/image classification, graph visualization, or molecule-only tasks unless PyG or graph neural network modeling is explicit.

Overview

PyTorch Geometric is a library built on PyTorch for developing and training Graph Neural Networks (GNNs). Apply this skill for deep learning on graphs and irregular structures, including mini-batch processing, multi-GPU training, and geometric deep learning applications.

Naming Compatibility

Use torch-geometric as the canonical skill ID. Treat torch_geometric, PyG, and pytorch geometric as API or keyword spellings that route to this same skill, not as separate expert roles.
