Crab - A Recommendation Engine library for Python

Crab is a flexible, fast recommender engine for Python that integrates classic information filtering recommendation algorithms in the world of scientific Python packages (numpy, scipy, matplotlib). The engine aims to provide a rich set of components from which you can construct a customized recommender system from a set of algorithms.

Usage

For Usage and Instructions checkout the Crab Wiki

History

The project was started in 2010 by Marcel Caraciolo as a M.S.C related project, and since then many people interested joined to help in the project. It is currently maintained by a team of volunteers, members of the Python-Recsys Labs.

Dependencies

The required dependencies to build the software are Python >= 2.6, setuptools, Numpy >= 1.3, SciPy >= 0.7 and a working C/C++ compiler. This configuration matches the Ubuntu 10.04 LTS release from April 2010.

To run the tests you will also need nose >= 0.10.

Install

This package uses distutils, which is the default way of installing python modules. To install in your home directory, use::

python setup.py install --home

To install for all users on Unix/Linux::

python setup.py build
sudo python setup.py install

Testing

After installation, you can launch the test suite from outside the source directory (you will need to have nosetest installed)::

python -c "import crab; crab.test()"

Or you can test by calling::

make test

See web page http://python-recsys.github.com/install.html#testing for more information.
