The issue here and in the similar prs is the use of find_namespace_packages, that should only be used in a namespace package (like aqua) where the root of the namespaceis in another package. You should be using find_packages in packages that are self contained like this.

@mtreinish The issue I was getting is that the files at the top folder were not being included when creating a wheel file or using a zipped from git to install. The sub-folders with files were included correctly.

I thought according to: "...Full support for PEP 420 via find_namespace_packages(), which is also backwards compatible to the existing find_packages() for Python >= 3.3." at https://setuptools.readthedocs.io/en/latest/setuptools.html

So I thought find_namespace_packages was the way to go forwards.

Also, I tested both find_packages and find_namespace_packages and found that for both to include top files and internal folders I still need to add : 'qiskit_machine_learning' regardless of what function I use. Just changing the function to find_packages without the additional parameter didn't fix it. The solutions were:

packages=setuptools.find_packages(include=['qiskit_machine_learning','qiskit_machine_learning.*']),

or

packages=setuptools.find_namespace_packages(include=['qiskit_machine_learning', 'qiskit_machine_learning.*']),

But I changed to find_packages.
