Scikit-network is an open-source python package for machine learning on graphs.

Each graph is represented by its adjacency matrix in the sparse CSR format of scipy.

An overview of the package is presented in this notebook.


To install scikit-network, run this command in your terminal:

$ pip install scikit-network

If you don’t have pip installed, this Python installation guide can guide you through the process.

Alternately, you can download the sources from Github and run:

$ cd <scikit-network folder>
$ python setup.py develop


Import scikit-network in Python:

import sknetwork as skn


A graph is represented by its adjacency matrix (square matrix). When the graph is bipartite, it can be represented by its biadjacency matrix (rectangular matrix). Check our tutorial for various ways of loading a graph (from a list of edges, a dataframe or a CSV file, for instance).

Each algorithm is represented as an object with a fit method.

Here is an example to cluster the Karate club graph with the Louvain algorithm:

from sknetwork.data import karate_club
from sknetwork.clustering import Louvain

adjacency = karate_club()
algorithm = Louvain()
