Cannot find reference 'v4' in '__init__.py'? :/#2807

I'm trying to add some type hints to my functions, e.g.project: gitlab.v4.objects.Project.

However, I am getting this pesky warning from IDEA:

Am I doing something wrong? 😓 What am I missing?

This would be perfectly fine for mypy. I guess you're hitting a pycharm/IDEA bug where it expects that package exposed via__all__:

You can probably work around it by importing it directly. Dummy code:

fromgitlab.v4.objectsimportProjectdefget_project(project:Project)->Nonepass

I wanted to avoidfrom gitlab.v4.objects import Project, because then, I had toimport everything:

Project, jobs.ProjectJob, ProjectMergeRequest, etc

And doingfrom gitlab.v4 import objects sounds ... atrocious (seeing it randomly in the code, would make me ask "object.? What "object"??"

But I solved my problem withfrom gitlab.v4 import objects as gobjects

Thank you for the suggestion / digging 🙃

Glad you got it to work! Yes, the exact level at which you import is up to you, as long as you trick your IDE's type checker around the__all__ bug. 🙂

... truth be told though, it's impossible to write:

I am very much missing the point in Python imports, namespaces, and packaging though, so - I could very well be wrong.

You might be mixing up class import (from abc import xyz) with module/package imports (import abc). It's up to you how you want to import them but you should use the right way to access them then - don't try to import a class without afrom syntax.

>>>importgitlab.v4.objects>>>gitlab.v4.objects.Project<class'gitlab.v4.objects.projects.Project'>>>>importgitlab.v4.objects.projects>>>gitlab.v4.objects.projects.Project<class'gitlab.v4.objects.projects.Project'>>>>fromgitlab.v4.objectsimportProject>>>Project<class'gitlab.v4.objects.projects.Project'>
