Note: if you are reporting a wrong signature of a function or a class in
the standard library, then the typeshed tracker is better suited
for this report: https://github.com/python/typeshed/issues

Please provide more information to help us understand the issue:

• Are you reporting a bug, or opening a feature request?
• Please insert below the code you are checking with mypy,
  or a mock-up repro if the source is private. We would appreciate
  if you try to simplify your case to a minimal repro.
• What is the actual behavior/output?
• What is the behavior/output you expect?
• What are the versions of mypy and Python you are using?
  Do you see the same issue after installing mypy from Git master?
• What are the mypy flags you are using? (For example --strict-optional)
• If mypy crashed with a traceback, please paste
  the full traceback below.

My layout

~/Playground/classroom/
    __init__.py
    app/
        quizzes.py
        utils.py
        __init__.py

Inside quizzes.py I have from classroom.app.utils import myfoo

And when I run (inside classroom folder) $ mypy app/quizzes.py

I got the error app/quizzes.py:13: error: Cannot find module named 'classroom.app.utils'

The key seems to be the current working directory. If I type check the code using mypy classroom/app/quizzes.py it works as expected.

Mypy should probably find the root of the package hierarchy (by looking at __init__.py files) and use the root in the module search path. This way you could run mypy in any nested package directory.

Is this really a bug? Just running python app/quizzes.py from the classroom/ directory (or even python classroom/app/quizzes.py from the top-level directory) would result in the same ImportError.

I don't see why mypy should behave any differently (and unexpectedly!).

Yeah, this was previously discussed, and we decided to not do it, see #6660. There was added a clarification about this in the docs, see #6676. So I would propose to just close this.

[JukkaL]

Since the current behavior is already documented, I agree that this can be closed. However, I still think that mypy could do better here to help beginners. I'll create a separate issue about generating a better error messages -- we could detect the issue and ask the user to change the current working directory.
