Alternatives
============

* https://github.com/chokkan/crfsuite/tree/master/swig/python - official
Python wrapper, exposes C++ API using SWIG.
* https://github.com/jakevdp/pyCRFsuite - uses C API instead of C++ API;
allows to use scipy sparse matrices as an input. At the time of writing
it is unmaintained.

This package (python-crfsuite) wraps CRFsuite C++ API using Cython.
It is faster than official SWIG wrapper and has a simpler codebase than
a more advanced pyCRFsuite. python-crfsuite works in Python 2 and Python 3,
doesn't have external dependencies (CRFsuite is bundled, numpy/scipy stack
is not needed) and workarounds some of the issues with C++ CRFsuite library.
