How to setup Python package config file using setup.cfg

I am working on packaging a Python project that has the directory structure:

package-main (located on Desktop)
   - my_package
       - __init__.py
       - datasets
       - plot.py
       - shapefiles
           - __init__.py
           - shapefile1
                - shapefile1.shp
                - shapefiel1.dbf
                - (and 4 other file formats)
           - shapefile2
                - shapefile2.shp
                - shapefiel2.dbf
                - (and 4 other file formats)
       - utils.py
       - states.py
       - my_package.egg-info
   - LICENSE.txt
   - setup.cfg
   - README.md
   - tests
   - docs
   - pyproject.toml
   - dist
   - my_package.egg-info

I am running into a problem where when I upload the package my_package to testPyPI, and then download the package to my local machine using the command:

pip install my_package

it is not downloading all of the files.

When I create a venv to check the package files, and then go into the package files for the virtual environment it only shows:

my_package
my_package-0.1.1.dist-info

When I open up the my_package directory all I see is the following structure:

my_package
   - __init__py
   - __pychache__
   - plot.py
   - shapefiles
        - __init__.py
        - __pychache__
   - states.py
   - utils.py

I have determined that this must have something to do with how I setting up the setup.cfg file (perhaps I am not telling it to download all of the package files?

My current setup.cfg file looks like this:

[options]
install_requires =
    numpy
    geopandas
    matplotlib
python_requires = >=3.6

packages = find:

I have read the documentation for setuptools here, but this does not fully clear things up for me. I need to tell the package to download the shape files as well.

I have seen multiple examples on how to do this with setup.py, but since it was advised on the Python packaging tutorial that I do not use this method since its dynamic vs static, I have not been able to find any examples online of how to do this.

Any links to resources or examples would be greatly appreciated.

Question: How do I change the setup.cfg file to make sure that it downloads all of the files the package needs to function correctly?

Edit:

The MANIFEST.in file looks like this:

include my_package/shapefiles/shapefile1/*.shp
include my_package/shapefiles/shapefile1/*.dbf

include my_package/shapefiles/shapefile2/*.shp
include my_package/shapefiles/shapefile2/*.dbf

Solution

According to setuptools docs on "Configuring setup() using setup.cfg files", you could try the following:

[options]
...
include_package_data = True
...

[options.package_data]
* = *.dbf, *.shp, *.ext1, *.ext2, *.ext3, *.ext4
