python submodule can't find import

Question

So I have a module called gann which itself has a number of modules, the problem is that if I run gannController.py directly it fails.

I have the following file structure(some files omitted):

----convert
 __init__.py
 convert.py
 ----AI
 __init__.py
 ----gann
 gannController.py
 ----model
 __init__.py 
 modelController.py 
 ----util 

now I want to use the gannController.py in the convert.py file.

from AI.gann import gannController

in convert.py does import gannController, however it crashes on the first line which is

from model import modelController

which does work if I run gannController.py directly. As it gives the error:

ModuleNotFoundError: No module named model

So I guess that it's because a submodule uses a submodule of it's own that I cannot run this. Anybody know how to fix this? It's worth noting that I would prefer not to pollute my convert namespace with all of the stuff in model and that I have omitted a few other modules that have the same situation (inside util)

• Thijser: I'm of course open to question/suggestions. And thank you for taking the time to read my question.
• GProst: What is the error?
• Thijser: @GProst ModuleNotFoundError: No module named model
• Eduardo Barrancos: from model import modelController This line is in which file?
• alani: @EduardoBarrancos It is in gannController.py according to the question.

Change your import to be relative:

from .model import modelController
