GraphNeuralNetworks.jl

This is the monorepository for the GraphNeuralNetworks project, bringing together all code into a unified structure to facilitate code sharing and reusability across different project components. It contains the following packages:

• GraphNeuralNetwork.jl: Package that contains stateful graph convolutional layers based on the machine learning framework Flux.jl. This is the fronted package for Flux users. It depends on GNNlib.jl, GNNGraphs.jl, and Flux.jl packages.

• GNNLux.jl: Package that contains stateless graph convolutional layers based on the machine learning framework Lux.jl. This is fronted package for Lux users. It depends on GNNlib.jl, GNNGraphs.jl, and Lux.jl packages.

• GNNlib.jl: Package that contains the core graph neural network layers and utilities. It depends on GNNGraphs.jl and GNNlib.jl packages and serves for code base for GraphNeuralNetwork.jl and GNNLux.jl packages.

• GNNGraphs.jl: Package that contains the graph data structures and helper functions for working with graph data. It depends on Graphs.jl package.

Among its general features:

• Implements common graph convolutional layers both in stateful and stateless form.
• Supports computations on batched graphs.
• Easy to define custom layers.
• CUDA support.
• Integration with Graphs.jl.
• Examples of node, edge, and graph level machine learning tasks.
• Heterogeneous and temporal graphs.

Installation

GraphNeuralNetworks.jl, GNNlib.jl and GNNGraphs.jl are a registered Julia packages. You can easily install a package, for example GraphNeuralNetworks.jl, through the package manager :

pkg> add GraphNeuralNetworks

Usage

Usage examples can be found in the examples and in the notebooks folder. Also, make sure to read the documentation for a comprehensive introduction to the library and the tutorials.
