RecBole-GNN is a library built upon PyTorch and RecBole for reproducing and developing recommendation algorithms based on graph neural networks (GNNs). Our library includes algorithms covering three major categories:
- General Recommendation with user-item interaction graphs;
- Sequential Recommendation with session/sequence graphs;
- Social Recommendation with social networks.
Highlights
- Easy-to-use and unified API: Our library shares unified API and input (atomic files) as RecBole.
- Efficient and reusable graph processing: We provide highly efficient and reusable basic datasets, dataloaders and layers for graph processing and learning.
- Extensive graph library: Graph neural networks from widely-used library like PyG are incorporated. Recently proposed graph algorithms can be easily equipped and compared with existing methods.
Requirements
recbole==1.1.1
pyg>=2.0.4
pytorch>=1.7.0
python>=3.7.0
If you are using
recbole==1.0.1

Quick-Start
With the source code, you can use the provided script for initial usage of our library:
python run_recbole_gnn.py
If you want to change the models or datasets, just run the script by setting additional command parameters:
python run_recbole_gnn.py -m [model] -d [dataset]

Leaderboard
We carefully tune the hyper-parameters of the implemented models of each research field and release the corresponding leaderboards for reference:
- General recommendation on
MovieLens-1M

Efficiency
With the sequential/session graphs preprocessing technique, as well as efficient GNN layers, we speed up the training process of our sequential recommenders a lot.
