The HyperNetX (HNX) library provides classes and methods for the analysis and visualization of complex network data modeled as hypergraphs. The library generalizes traditional graph metrics. Documentation for HNX is available at: https://hypernetx.readthedocs.io/
HNX was originally developed by the Pacific Northwest National Laboratory for the Hypernets project as part of its High Performance Data Analytics (HPDA) program. It is currently maintained by scientists at PNNL, but contributions and bug fixes from the community are welcome and encouraged. Please see our Contributor's Guide for more information.
PNNL is operated by Battelle Memorial Institute under Contract DE-ACO5-76RL01830.

The code in this repository is intended to support researchers modeling data as hypergraphs. We have a growing community of users and contributors. HNX is a primary contributor to the Hypergraph Interchange Format (HIF), a json schema for sharing data modeled as hypergraphs. The specification and sample notebooks may be found here: https://github.com/pszufe/HIF-standard/tree/main Other hypergraph libraries using this standard are listed below:
- HypergraphX (HGX) (Python)
- CompleX Group Interactions (XGI) (Python)
- SimpleHypergraphs.jl (Julia)
- Hypergraph-Analysis-Toolbox(HAT) (Python)

HyperNetX 2.3. is the latest, stable release. The core library has been refactored to take better advantage of Pandas Dataframes, improve readability and maintainability, address bugs, and make it easier to change. New features have been added, most notably the ability to add and remove edges, nodes, and incidences.
Version 2.3 is not backwards compatible. Objects constructed using earlier versions can be imported using their incidence dictionaries and/or property datafames.
- Hypergraph now supports adding and removing edges, nodes, and incidences
- Hypergraph also supports the sum, difference, union, and intersection of a Hypergraph to another Hypergraph
- New factory methods to support the Hypergraph constructor
- EntitySet has been replaced by HypergraphView
- IncidenceStore and PropertyStore are new classes that maintain the structure and attributes of a Hypergraph
- Hypergraph constructors accept cell, edge, and node metadata.
- HNX now requires Python ">=3.10,<4.0.0"
- HNX core libraries have been updated
- Updated tutorials
- The
staticanddynamicdistinctions no longer exist. All hypergraphs use the same underlying data structure, supported by Pandas dataFrames. All hypergraphs maintain astate_dictto avoid repeating computations. - The
nwhyoptimizations are no longer supported.

The recommended installation method for most users is to create a virtual environment and install HyperNetX from PyPi.
HyperNetX may be cloned or forked from GitHub.
HyperNetX officially supports Python >=3.10,<4.0.0
python -m venv venv-hnx
source venv-hnx/bin/activateconda create -n venv-hnx python=3.11 -y
conda activate venv-hnxvirtualenv venv-hnx
source venv-hnx/bin/activateOn both Windows PowerShell or Command Prompt, you can use the following command to activate your virtual environment:
.\env-hnx\Scripts\activateTo deactivate your environment, use:
.\env-hnx\Scripts\deactivateRegardless of how you install HyperNetX, ensure that your environment is activated and that you are running Python ">=3.10,<4.0.0".
pip install hypernetxEnsure that you have git installed.
git clone https://github.com/pnnl/HyperNetX.git
cd HyperNetX
# Create a virtual environment
make venv
source venv-hnx/bin/activate
# install required dependencies
make installAs an alternative to installing HyperNetX, you can use the officially supported HyperNetX Docker image maintained at DockerHub. Use the image to quickly start HyperNetX in a Docker container. The container starts a Jupyter Notebook that has the latest version of HyperNetX and HNXWidget installed; it also contains all the HyperNetX tutorials.
- Using Docker CLI, run the container in the foreground:
docker run -it --rm -p 8888:8888 -v "${PWD}":/home/jovyan/work hypernetx/hypernetx:latest
- Alternatively, you can create a
docker-compose.ymlfile with the following:
version: '3'
services:
hypernetx:
image: hypernetx/hypernetx:latest
ports:
- "8888:8888"
tty: true
stdin_open: true
volumes:
- "${PWD}:/home/jovyan/work"
Once docker-compose.yml is created, run the container:
docker-compose up
After the container has started, access the HyperNetX Jupyter Notebooks by opening the following URL in a browser:
As a developer, set up your environment using either the standard pip tool or Poetry.
Create a virtual environement. Then install an editable version of HNX and also install additional dependencies to support testing and jupyter notebooks:
python -m venv venv-hnx
source venv-hnx/bin/activate
pip install -e .
pip install -r requirements.txt
As an alternative, you can also install all these requirements in one Make target:
make venv
source venv-hnx/bin/activate
make install
Use the pre-commit framework to automatically point out issues and resolve those issues before code review. It is highly recommended to install pre-commit in your development environment so that issues with your code can be found before you submit a pull request. More importantly, using pre-commit will automatically format your code changes so that they pass the CI build. For example, pre-commit will automatically run the formatter Black on your code changes.
# Once installed, pre-commit will be triggered every time you make a commit in your environment
pre-commit installThis library uses Poetry to manage dependencies and packaging. Poetry can also be used to manage your environment for development.
Configure your Poetry to ensure that the virtual environment gets created in your project directory (this is not necessary but recommended for convenience):
poetry config virtualenvs.in-project true
# check the poetry configuration
poetry config --list
Create and activate a virtual environment.
poetry shell
Install HyperNetX in editable mode, the library's core/required dependencies, and the optional dependencies to support development.
poetry install --with test,lint,docs,release,tutorials
Details about these dependencies are defined in pyproject.toml.
