scikit-network is an open-source python package for the analysis of large graphs.

Each graph is represented by a sparse scipy CSR matrix.

Install

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 the Github repo and run:

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

Import

Import scikit-network in Python:

import sknetwork as skn

Load

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).

Fit

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()
algo = Louvain()
algo.fit(adjacency)
labels = algo.labels_
