November 27, 2024 - Docker containers are just Linux environments, make sure your python path is set and your project structure is clean and there should be no more issues than if you were local ... Let me give you a scenario. You get existing code in a repo. You are told to fix a few bugs. You spin up Docker Compose but there seems to be some problem with how the code mounts to the container. Run an api request to test the code and "ta-da" ModuleNotFoundError: No module named... yes the __init__.py is there and yes the PYTHONPATH is set but there is something buggy with a few imports.

January 16, 2025 - Running as a module with -m places the current directory in the 1st index in sys.path , running as a script places the immediate parent directory of the script in the 1st index in sys.path . These 2 paths may be the same when the project hierarchy is simple and not nested, or when you run the program from a directory right above the module (python file), so nothing to worry here. However, when these 2 paths start differing, you can print sys.path to debug. Absolute imports use the full path of the module from the project root, relative imports use dot notation.

Traps for the Unwary in Python’s Import System - Alyssa Coghlan's Python Notes
If you’re not a core developer on a Python implementation, the problem of importing stale bytecode is most likely to arise when renaming Python source files. For Python implementation developers, it can also arise any time we’re working on the compiler components that are responsible for generating the bytecode in the first place - that’s the main reason the CPython Makefile includes a make pycremoval target. Many users will have experienced the issue of trying to use a submodule when only importing the package that it is in:

Fix circular import issues in Python projects?
December 8, 2025 - Move shared logic into a common utilities module. Never let two modules depend on each other directly. Use lazy imports or TYPE_CHECKING when needed. These practices help large Python projects stay clean, maintainable, and error-free. Circular import issues in Python can interrupt your entire project, but they are easy to fix once you understand why they occur.

is main/src in sys.path? Python resolves module names by searching the directories in sys.path. For example "import ../module.py" is not valid. To fix your problem do something like this: In your "main/tests/test.py" file add:
import sys, os
sys.path.insert(0, os.path.abspath("../src") )
# Then try
from domain.entries import MyClass
You will also need to make sure that main/src/domain contains an init.py file. Also you don't need init.py in main/tests unless your going to add it's parent directory to your path and import tests.something.
Hope this helps.

You shoud not add the project directory to your pythonpath but it's parent, e.g. imagine the setup
/home/user/develop/project/src/model
You'd add /home/user/develop to PYTHONPATH
If that still doesn't work, make sure you don't have a 'project.py' insite project/src/model.

Make sure you have the parent directory of project/ on your pythonpath, rather than the project directory. If you add the project path itself, imports like import project.src will look for project/project/src.
