graphtools

Tools for building and manipulating graphs in Python.

Installation

graphtools is available on pip. Install by running the following in a terminal:

pip install --user graphtools

Usage example

The graphtools.Graph class provides an all-in-one interface for k-nearest neighbors, mutual nearest neighbors, exact (pairwise distances) and landmark graphs.

Use it as follows:

from sklearn import datasets
import graphtools
digits = datasets.load_digits()
G = graphtools.Graph(digits['data'])
K = G.kernel
P = G.diff_op
G = graphtools.Graph(digits['data'], n_landmark=300)
L = G.landmark_op
