PyTorch Geometric (PyG) has quickly established itself as the go-to framework for building Graph Neural Networks (GNNs), a relatively new approach to AI that is particularly well-suited to modelling subject matter with irregular structures – from molecules to social networks, with the potential to be used in commercial applications as diverse as drug discovery and fraud detection.

At the same time, Graphcore IPUs have shown standout performance running GNNs, compared to other compute architectures – winning industry benchmarking competitions and being put to use in US national labs, commercial AI companies and academic research environments.

Now, for the first time, we are integrating PyG with Graphcore’s software stack, allowing users to build, port and run their GNNs on IPUs.

We are also making a range of example models available to run as Paperspace Gradient Notebooks. These span molecular science, temporal graph networks, knowledge graph prediction, and more.

Accelerating GNN uptake

Welcoming the partnership, PyG creator and founder of Kumo.ai, Matthias Fey said: “The suitability of IPUs for running GNNs and the kind of performance advantage that Graphcore and its customers have demonstrated is really helping to accelerate the uptake of this exciting model class.

“The integration of PyTorch Geometric will make it quicker and easier than ever for developers to create new GNNs from scratch, move existing models over to IPUs, or take advantage of the growing catalogue of off-the-shelf IPU-ready GNNs.”

Minimal code changes

Running a PyG model on Graphcore IPUs, for training or inference, requires only minimal code changes compared to using PyG on a GPU.

Our blog - Getting started with PyTorch Geometric (PyG) on Graphcore IPUs - shows how to get up and running in a matter of minutes.

Users who want to start using GNNs immediately can also choose from the following pre-built model notebooks using a six hour free trial on Paperspace.
