python-crfsuite is a python binding to CRFsuite.
Using pip:
pip install python-crfsuite
Using conda:
conda install -c conda-forge python-crfsuite
sklearn-crfsuite is a python-crfsuite wrapper which provides API similar to scikit-learn.

- 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.
- https://github.com/bosondata/crfsuite-rs - uses a Rust wrapper with CFFI instead of C++ API; allows to tag with GIL released for better performance.
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.
