ModuleNotFoundError: No module named 'findiff'

package findiff is correctly installed, what can I do?

Are you sure that you have installed findiff to the correct environment?

Did you install findiff using pip in a virtual environment or systemwide? Or did you install using setup.py based on the code?

I have installed it both in venv and in the system but the problem persists
