tensorflow-gnn 1.0.1

A library for building scalable graph neural networks in TensorFlow.

TensorFlow GNN

Summary

TensorFlow GNN is a library to build Graph Neural Networks on the TensorFlow platform. It provides...

• a tfgnn.GraphTensor type to represent graphs with a heterogeneous schema, that is, multiple types of nodes and edges;
• tools for data preparation, notably a graph sampler to convert a huge database into a stream of reasonably-sized subgraphs for training and inference;
• a collection of ready-to-use models and Keras layers to do your own GNN modeling;
• a high-level API for training orchestration.

This library is an OSS port of a Google-internal library used in a broad variety of contexts, on homogeneous and heterogeneous graphs, and in conjunction with other scalable graph mining tools.

For background and discussion, please see O. Ferludin et al.: TF-GNN: Graph Neural Networks in TensorFlow, 2023 (full citation below).

Quickstart

Google Colab lets you run TF-GNN demos from your browser, no installation required:

• Molecular Graph Classification with the MUTAG dataset.
• Solving OGBN-MAG end-to-end trains a model on heterogeneous sampled subgraphs from the popular OGBN-MAG benchmark.
• Learning shortest paths with GraphNetworks demonstrates an advanced Encoder/Process/Decoder architecture for predicting the edges of a shortest path.

For all colabs and user guides, please see the Documentation overview page, which also links to the API docs.

Installation Instructions

The latest stable release of TensorFlow GNN is available from

pip install tensorflow_gnn

For installation from source, see our Developer Guide.

Key platform requirements:

• TensorFlow 2.12, 2.13, 2.14 or 2.15, and any GPU drivers it needs [instructions].
• Keras v2, as traditionally included with TensorFlow 2.x. (TF-GNN does not work with the new multi-backend Keras v3.)
• Apache Beam for distributed graph sampling.

TF-GNN is developed and tested on Linux. Running on other platforms supported by TensorFlow may be possible.
