Python doesn’t find local module although it is installed

I have created a package containing some python files using setup.py. Built the package using pip install .
I installed the package locally in my project as it is not published. But I am unable to import it.
You can see in image that package is successfully installed and listed in site-packages.

The package directory name needs to use underscores. Dashes are not valid in Python identifiers.

Thank You it work.
