Scikit-learn, Scikit-image, Statsmodels, and Pillow (PIL) naming conventions

All Enthought Python users have access to the popular and powerful packages scikit-image, scikit-learn, statsmodels, and Pillow (PIL). These can be installed with the Enthought Deployment Manager (EDM).

For historical reasons, the following names come into play for each of these packages.

Scikit-Learn

scikit-learn - the name of the package as listed on the project's website.

scikit_learn - the name of the package to download and install.

sklearn - the name of the module to import.

scikits.learn - the name of the older version of the package, visible in Python 2 with old versions of Canopy. Do not try to install this, as it will cause conflicts.

Scikit-Image

scikit-image - the name of the package as listed on the project's website.

scikits.image - the name of the package to download and install. This older name is still being used by Enthought Python to search/install/remove the package. This is different from the official PyPI repo used by pip / easy_install, which uses scikit-image. 

skimage - the name of the module to import.

Statsmodels

Statsmodels - the name of the package to install and import.

scikits.statsmodels -the name of the older version of the package, visible in Python 2 with old versions of Canopy. Do not try to install this, as it will cause conflicts.

Pillow (Formerly PIL - Python Imaging Library)

pillow - the name of the package to install, which provides a fully compatible, but updated, replacement for pil.

PIL - the name of the package to import after you have installed pillow!

pil - the name of the older version of the package, visible in Python 2 with old versions of Canopy. Do not try to install this, as it will cause conflicts.
