Python: Weird Import Behaviour

I have a package with the following structure projectX ├── data ├── results └── projectX ├── stats │ ├── __init__.py │ ├──

Solution 1:

1. Add an empty __init__.py file into the source root.
2. Your runtime environment will need to be setup so that the project root is visible in sys.path. The project root should not have an __init__.py. It isn't necessary for the project directory name to match the package name, but that doesn't really harm anything either.
3. Remove any sys.path.append stuff from python source files, and don't ever do that again.
4. from projectX import main_worker is a correct import statement for the stats_worker2.py module. Don't use import main_worker.

For step 2, the usual way to do this is via "installing" your package, with python setup.py develop. i.e. you need to write a setup.py. Since you apparently don't have a setup.py, as a cheap workaround you can export PYTHONPATH=<absolute_path_to_project_root> instead.

_{Source root is the deeper projectX dir, it's the same directory which contains the main_worker.py module.}

_{Project root is the shallow projectX dir, it's the same directory which contains data and results subdirectories.}
