Question

although there are many posts on the internet as well as some posts on stack overflow, I still want to ask about this nasty python “import” problem.

OK. so, the open source code organization is usually like this:

project/src/model.py;

project/test/testmodel.py

if I put the famous __init__.py in project directory and also in src/ and test/ subdirectories,
and then put “from project.src import model” for the testmodel.py.
it does not work! keep telling me that the Module named “project.src” is not found!

how can I solve the problem without changing the code structure?

Answer 1

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.
