Python Packaging Multiple Subpackages With Different Data Directories

I have a structure of the directory as such with foobar and alphabet data directories together with the code something.py: \mylibrary \packages \foobar fo

Solution 1:

Firs you have to package and publish alphabet and foobar as a separate packages as pip install mylibrary[alphabet] means

pip install mylibrary
pip install alphabet

After that add alphabet and foobar as extras:

setup(
    …,
    extras = {
        'alphabet': ['alphabet'],
        'foobar': ['foobar'],
    }
)

The keys in the dictionary are the names used in pip install mylibrary[EXTRA_NAME], the values are a list of package names that will be installed from PyPI.

PS. And no, you cannot use extras to install some data files that are not available as packages from PyPI.
