Python binding

How to build

The binding uses Cython. To package the library, use python setup.py bdist_wheel. Install the package by pip install --user pspartition. Below is the pre-built binary packages:

Demo code

import pspartition # classify the three data points shown in the above figure
g = pspartion.PsPartition(3, [(0,1,1),(1,2,1),(0,2,5)]) # index started from zero, similarity is 5 for vertex 0 and 2
g.run() # default to use psp_i algorithm to classify them
print(g.get_critical_values()) # [2,5]
print(g.get_partitions()) # get the result which has at least 2 categories, which is [0,1,0]

ChangeLog

• Version 0.2: expose PSP (C++) class, which is high customizable in python.
• Version 0.3: expose PyGraphPDT (C++) class, which has similar API as PyGraph but different inner implementation.
• Version 0.5: expose run_psp_i for InfoCluster.
• Version 0.7: change the python binding name from info_cluster to pspartition.
