[FIXED] How to import locally installed library?

Issue

I've installed my library using the following command:

pip install .

Here is the directory structure:

└───module1
    ├───__init__.py
    └───mod_1.py
└───module2
    ├───__init__.py
    └───mod_2.py
__init__.py
setup.py

inside setup.py

from setuptools import setup,find_packages
setup(
    name = "my_lib",
    version="1.0.0",
    packages=find_packages(),
    python_requires='>=3.7',
    include_package_data=True,
    zip_safe=False)

Installed in:

.\Python\Python312\Lib\site-packages
└───module1
    ├───____pycache__
    ├───__init__.py
    └───mod_1.py
└───module2
    ├───____pycache__
    ├───__init__.py
    └───mod_2.py
└───my_lib-1.0.0.dist-info
    ├───direct_url.json
    ├───INSTALLER
    ├───METADATA
    ├───RECORD
    ├───REQUESTED
    ├───top_level.txt
    └───WHEEL

Expected behavior/import:

from my_lib import mod_1, mod_2

Current error is:

ModuleNotFoundError: No module named 'my_lib'

Work around:

import mod_1, mod_2

Need help with:

What do I need to change in my structure\setup.py in order to import "my_lib" as following?

from my_lib import mod_1, mod_2

Solution

Move module1 and module2 into a my_lib directory, and add this to my_lib/__init__.py (also note I removed the root __init__.py as it is not needed.)

from .module1 import mod_1
from .module2 import mod_2
