The HNX library provides classes and methods for modeling the entities and relationships found in complex networks as hypergraphs, the natural models for multi-dimensional network data. As strict generalizations of graphs, hyperedges can represent arbitrary multi-way relations among entities, and in particular can distinguish cliques and simplices, and admit singleton edges. As both vertex adjacency and edge incidence are generalized to be quantities, hypergraph paths and walks thereby have both length and width because of these multiway connections. Most graph metrics have natural generalizations to hypergraphs, but since hypergraphs are basically set systems, they also admit to the powerful tools of algebraic topology, including simplicial complexes and simplicial homology, to study their structure.
This library serves as a repository of the methods and algorithms we find most useful as we explore what hypergraphs can tell us. We have a growing community of users and contributors. To learn more about some of our research check out our publications below:

The code in this repository is intended to support researchers modeling data
as hypergraphs. We have a growing community of users and contributors.

New Features of Version 1.0
- Hypergraph construction can be sped up by reading in all of the data at once. In particular the hypergraph constructor may read a Pandas dataframe object and create edges and nodes based on column headers. The new hypergraphs are given an attribute
- A C++ addon called NWHy can be used in Linux environments to support optimized hypergraph methods such as s-centrality measures.
- Four new tutorials highlighting the s-centrality metrics, static Hypergraphs, NWHy, and Hypernetx-Widget.
New Features of Version 1.1
- Static Hypergraph refactored to improve performance across all methods.
- Added modules and tutorials for Contagion Modeling, Community Detection, Clustering, and Hypergraph Generation.
- Cell weights for incidence matrices may be added to static hypergraphs on construction.

To install in an Anaconda environment
>>> conda create -n <env name> python=3.7 >>> source activate <env name> >>> pip install hypernetx
Mac Users: If you wish to build the documentation you will need
the conda version of matplotlib:
>>> conda create -n <env name> python=3.7 matplotlib >>> source activate <env name> >>> pip install hypernetx
>>> conda create -n <env name> python=3.9 tbb >>> source activate <env name> >>> pip install hypernetx >>> pip install nwhy
To install in a virtualenv environment
>>> virtualenv --python=<path to python 3.7 executable> <path to env name>
This will create a virtual environment in the specified location using
the specified python executable. For example:
>>> virtualenv --python=C:\Anaconda3\python.exe hnx
This will create a virtual environment in .\hnx using the python
that comes with Anaconda3.
>>> <path to env name>\Scripts\activate<file extension>
If you are running in Windows PowerShell use
If you are running in Windows Command Prompt use
Once activated continue to follow the installation instructions below.
Install using Pip options
For a minimal installation:
>>> pip install hypernetx
For an editable installation with access to jupyter notebooks:
>>> pip install [-e] .
To install with the tutorials:
>>> pip install -e .['tutorials']
To install with the documentation:
>>> pip install -e .['documentation'] >>> chmod 755 build_docs.sh >>> sh build_docs.sh ## This will generate the documentation in /docs/build/ ## Open them in your browser with /docs/index.html
To install and test using pytest:
>>> pip install -e .['testing'] >>> pytest
To install the whole shabang:
>>> pip install -e .['all']
