My scikit-learn compatible library of categorical data encoders (category_encoders) is now published on conda forge! Conda, if you didn't know, is an open source package manager for python (and other things) developed primarily by continuum analytics. Thanks to continuum developer https://github.com/bollwyvl for doing pretty much all of the work to get it working.
Check out the category_encoders feedstock here: https://github.com/conda-forge/category_encoders-feedstock and check out the other packages on conda forge here: https://conda-forge.github.io/feedstocks.html
If you haven't already checked out conda or category_encoders, try out both, and let me know what you think.
