Python: ModuleNotFoundError: No module named "core" found while running the installed package

Question

Here is my package structure:

upgradehost
    |
    |_ _ upgradehost
    |   |
    |   |_ app.py 
    |   |
    |   |_ core.py
    |   |
    |   |_ stable.py
    |   |
    |   |_ __init__.py
    |
    |_ _ doc
    |
    |_ _ test
    |
    |_ _ setup.py
    |
    |_ _ __init__.py

My app.py contains following import:

from core import customlogger, upgradeHost  
from stable import vm_upgarde, disk_upgrade

My setup.py conains the following as parameters to setuptools.setup()

packages=['upgradehost'],
py_modules=['upgradehost.core', 'upgradehost.stable'],  # I added this after getting the "ModuleNotFoundError: No module named 'core'" the first time.

Then I tried to install the package.

> python setup.py install

creating build\bdist.win32\egg\upgradehost
copying build\lib\upgradehost\1.py -> build\bdist.win32\egg\upgradehost
copying build\lib\upgradehost\app.py -> build\bdist.win32\egg\upgradehost
copying build\lib\upgradehost\core.py -> build\bdist.win32\egg\upgradehost
copying build\lib\upgradehost\stable.py -> build\bdist.win32\egg\upgradehost
copying build\lib\upgradehost\__init__.py -> build\bdist.win32\egg\upgradehost

Then I try to run the application from the \Python\Python38-32\Scripts directory.

> upgradehost -h

ModuleNotFoundError: No module named 'core'

I need your kind help to let me know what is happening here and how this can be resolved. I am on Windows 10 and Python 3.8

Hi John, Thanks for your time. I resolved the error by doing 2 things: In the app.py file I put the full path of module. I changed "from core import customlogger, upgradeHost " to "from "upgradehost.core import customlogger, upgradeHost" .. The next change I did was changing packages=['upgradehost'] to packages=setuptools.find_packages() ... I followed the suggestion from here: https://stackoverflow.com/questions/59305504/modulenotfounderror-no-module-named-modulename-after-pip-install — May, Jul 31 '20 at 01:48
