The HyperNetX library provides classes and methods for the analysis and visualization of complex network data modeled as hypergraphs. The library generalizes traditional graph metrics.
HypernetX was developed by the Pacific Northwest National Laboratory for the Hypernets project as part of its High Performance Data Analytics (HPDA) program. 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. Documentation is available at: https://pnnl.github.io/HyperNetX

HNX 2.0 now accepts metadata as core attributes of the edges and nodes of a hypergraph. While the library continues to accept lists, dictionaries and dataframes as basic inputs for hypergraph constructions, both cell properties and edge and node properties can now be easily added for retrieval as object attributes.
The core library has been rebuilt to take advantage of the flexibility and speed of Pandas Dataframes. Dataframes offer the ability to store and easily access hypergraph metadata. Metadata can be used for filtering objects, and characterize their distributions by their attributes.
Version 2.0 is not backwards compatible. Objects constructed using version 1.x can be imported from their incidence dictionaries.
- The Hypergraph constructor now accepts nested dictionaries with incidence cell properties, pandas.DataFrames, and 2-column Numpy arrays.
- Additional constructors accept incidence matrices and incidence dataframes.
- Hypergraph constructors accept cell, edge, and node metadata.
- Metadata available as attributes on the cells, edges, and nodes.
- User-defined cell weights and default weights available to incidence matrix.
- Meta data persists with restrictions and removals.
- Meta data persists onto s-linegraphs as node attributes of Networkx graphs.
- New hnxwidget available using
pip install hnxwidget.
- 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. - Methods for adding nodes and hyperedges are currently not supported.
- The
nwhyoptimizations are no longer supported. - Entity and EntitySet classes are being moved to the background. The Hypergraph constructor does not accept either.

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 3.8, 3.9, 3.10 and 3.11.
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 >=3.8.
pip install hypernetxEnsure that you have git installed.
git clone https://github.com/pnnl/HyperNetX.git
cd HyperNetX
make venv
source venv-hnx/bin/activate
pip install .pip install -e .
pip install -e .['all']
# for zsh users
pip install -e .'[all]'âšī¸ NOTE: This project has a pytest configuration file named 'pytest.ini'. By default, pytest will use those configuration settings to run tests.
make test-deps
# run tests
python -m pytest
# run tests and show coverage report
python -m pytest --cov=hypernetx
# Generate an HTML code coverage report and view it on a browser

make tutorialsHyperNetX uses a number of tools to maintain code quality:
- Pylint
- Black
Before using these tools, ensure that you install Pylint in your environment:
make lint-depsPylint is a static code analyzer for Python-based projects. From the Pylint docs:
Pylint analyses your code without actually running it. It checks for errors, enforces a coding standard, looks for code smells, and can make suggestions about how the code could be refactored. Pylint can infer actual values from your code using its internal code representation (astroid). If your code is import logging as argparse, Pylint will know that argparse.error(...) is in fact a logging call and not an argparse call.
To run Pylint and view the results of Pylint, run the following command:
pylint hypernetxYou can also run Pylint on the command line to generate a report on the quality of the codebase and save it to a file named "pylint-results.txt":
pylint hypernetx --output=pylint-results.txtFor more information on configuration, see https://pylint.pycqa.org/en/latest/user_guide/configuration/index.html
Black is a PEP 8 compliant formatter for Python-based project. This tool is highly opinionated about how Python should be formatted and will automagically reformat your code.
make format-deps
black hypernetxmake docs-deps
cd docs
make html
open docs/build/html/index.html
When editing documentation, you can auto-rebuild the documentation locally so that you can view your document changes live on the browser without having to rebuild every time you have a change.
make docs-deps
cd docs
make livehtml
This make script will run in the foreground on your terminal. You should see the following:
The HTML pages are in docs/html.

This project runs Continuous Integration (CI) using GitHub Actions. Normally, CI runs on pull requests, pushes to certain branches, and other events.
Maintainers of the GitHub repository can manually trigger CI using GitHub CLI. See instructions below on how to manually trigger CI on GitHub Actions:
# login to Github
gh auth login --with-token < ~/.ssh/tokens/<path to my personal access token>
# Trigger CI
gh workflow run ci.yml --repo pnnl/HyperNetX --ref <name of branch that you want CI to run on> --field triggeredBy="<Your name>"
# Get the status of the workflow
gh run list --workflow=ci.yml --repo pnnl/HyperNetX
This project uses commitizen to manage versioning.
The files where "version" will be updated are listed in the '.cz.toml' file. To create a new version and the associated tag,
run the following commands:
# Install commitizen tool to environment
make version-deps
# Updates version; values for '--increment' can be MAJOR, MINOR, or PATCH
# Autocreates a tag and commit for the updated version
cz bump --increment MAJOR --dry-run
