Packaging python project with multiple directories

I need some explanation on working with setuptools and find_packages function. I have a project structure like this:

├── project_dir_1 │ ├── module.py │ ├── __init__.py ├── my_project │ ├── cli.py │ ├── subdir1 │ │ ├── __init__.py │ │ ├── module.py │ ├── conf │ │ ├── module.py │ │ ├── params │ │ │ ├── config.yml │ │ ├── __init__.py │ ├── subdir2 │ │ ├── module.py │ ├── __init__.py │ └── version.py ├── project_dir_2 │ ├── subdir1 │ │ ├── module.py │ │ ├── __init__.py │ ├── __init__.py ├── README.md ├── requirements.txt ├── setup.py └── tests └── test_main.py 

Actually all my code in the my_project dir and I also have two additonal dirs project_dir_1 and project_dir_2 that contains necessary external modules from where I should do imports both in the package code and in another projects code where this package will be installed in venv. I have setup script like this:

setup( name='my_project', version='0.0.1', description='Python library.', license='license', author='me', author_email='my_email', entry_points={'console_scripts': ['my_project=my_project.cli:main']}, python_requires='>=3.7', packages=find_packages( include=['my_project', 'project_dir_1', 'project_dir_2', 'my_project.*', 'project_dir_1.*', 'project_dir_2.*'] ), install_requires=list(open(join(dirname(__file__), 'requirements.txt')).read().split()), ) 

When I activate venv in another project folder and trying to install package from package root folder like python ..\package_root\setup.py install everything seems to works fine during install. And pip list shows all dependencies and my_project 0.0.1. But if I'm trying to import something from my_project using the venv interpreter I got an error: ModuleNotFoundError: No module named 'my_project'. The same result if I'm trying to import something like from project_dir_1 import module which is also necessary. Also when I just run my_project from shell addressing to cli I got an error:

Traceback (most recent call last): File "/home/developer/another_project/env/bin/my_project", line 11, in <module> load_entry_point('my_project==0.0.1', 'console_scripts', 'my_project')() File "/home/developer/another_project/env/lib/python3.8/site-packages/pkg_resources/__init__.py", line 489, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/home/developer/another_project/env/lib/python3.8/site-packages/pkg_resources/__init__.py", line 2852, in load_entry_point return ep.load() File "/home/developer/another_project/env/lib/python3.8/site-packages/pkg_resources/__init__.py", line 2443, in load return self.resolve() File "/home/developer/another_project/env/lib/python3.8/site-packages/pkg_resources/__init__.py", line 2449, in resolve module = __import__(self.module_name, fromlist=['__name__'], level=0) ModuleNotFoundError: No module named 'my_project' 

So what is the right way to organize this complex project structure and include all necessary code in setup.py to get the setuptools install the package correctly? I need some better understanding of python projects packaging but still don't get an answers for this case from seeking the docs.
