OpenGM is a C++ template library for discrete factor graph models and distributive operations on these models.

It includes state-of-the-art optimization and inference algorithms beyond message passing. OpenGM handles large models efficiently, is modular and extendible. The graphical model data structure, inference algorithms and different encodings of functions inter-operate through well-defined interfaces. The binary OpenGM file format is based on the HDF5 standard and incorporates user extensions automatically.

This package contains the Python interface to the OpenGM library.
