pycharm can't find main module in

PyCharm may not be able to find the main module in your Python project if the file containing the main method is not marked as the main module.

To fix this issue, follow these steps:

1. Right-click on the file containing the main method in the Project Explorer window.
2. Select "Mark Directory as" from the context menu.
3. Choose "Sources Root" from the submenu.

This will mark the directory containing the file as the sources root, and PyCharm will be able to find the main module.

If the file containing the main method is not in the same directory as the project root, you may need to add the directory containing the file to the Python path. To do this, go to File > Settings > Project > Project Interpreter and click on the gear icon next to the interpreter. Then, select "Show All" and add the directory to the list of paths.
