A tool for checking versions of packages used by conda or pip are as specified in their requirements files.
Picky is a tool for making sure that the packages you have installed with pip or conda match those you have specified.
It also will let you easily maintain those specifications, even in the situation where some packages are installed by pip while others are installed using conda.
This package provides a version of picky targeted at virtualenvs and other environments where pip is used to manage packages. If you require the version that targets conda environments, see picky-conda
