All the __init__.pys in the shown file structure are empty files. Consider a simple package layout like the following (I typically use package layouts along these lines in my own projects - a lot of people hate nesting tests inside package directories his comment is here The toplevel package for your project is my_project, so that must be the start of any import for something in your project.
