About the project

HyperTorch is a library for hypergraph learning and benchmarking. It provides a standardized workflow for loading hypergraph datasets, training models, evaluating them under comparable settings, and reporting results. The current release focuses on Hyperlink Prediction, with ready-to-run pipelines for established hypergraph baselines.

The library is built around extensibility: datasets are represented in HIF format and converted into typed tensor objects, models can be implemented as standard Lightning modules, and benchmarking is handled through reusable trainers, samplers, metrics, loggers, and result exporters (Markdown/LaTeX). HyperTorch includes preloaded datasets, mini-batch and full-hypergraph data loading, negative sampling utilities, structural feature enrichers, neural components, and built-in models such as HGNN, HNHN, HyperGCN, GCN, MLP/SLP, NHP, Node2Vec, VilLain, and more.

Use HyperTorch to:

  • Benchmark existing models across a shared collection of hypergraph datasets.
  • Develop custom PyTorch or PyTorch Lightning models and train and compare them against the built-in baselines.
  • Integrate new datasets through the HIF format and run the same training, evaluation, and reporting pipeline on them.

Getting started

For users working with the pip package manager, HyperTorch can be installed from PyPI.

pip install hypertorch

# if you want to install optional dependencies for tensorboard support:
pip install "hypertorch[tensorboard]"

or alternatively, using uv:

uv add hypertorch # or uv pip install hypertorch

# for optional dependencies for tensorboard support:
uv add "hypertorch[tensorboard]"

If you want to build the project from source, see the documentation for more details.

Run examples

You can download the examples directory and run the example scripts to get started.

With Python:

python3 examples/hyperlink_prediction/nhp.py

Or with uv:

uv run examples/hyperlink_prediction/nhp.py
