Fast implementation of the MRR ranking metric. Suitable to be used as custom metric in ranking algorithms, as they really ofter do not support it as a built-in ranking metric.

The code is written in Cython and therefore can be used in Python natively, but still is fast as C code.

You should build the Cython source code before using the function Do it by:

python setup.py build_ext --inplace

See example.py for a complete example
