ModuleNotFoundError with importlib.import_module for submodule

(my english is really bad sorry)

I write a OOP code and I want a main file who import (auto with importlib) some "templates" to execute. Every templates have a "main file" and others objects for a good oriented programmation. BUT I can't import my "main module" beacause importlib raise ModuleNotFoundError directly on import object at the beginning code (example below). Please help ! I try to resolve with inspect lib and ModuleFinder lib or force at parsing my file name in os.listdir but... nothing... I'm totally blocked.

--main.py
--templates/
---__init__.py
---Beer/
----__init__.py
----Beer.py
----Livraison.py

main.py

...
def import_templates(package, recursive=True):
    if isinstance(package, str):
        print(package)
        package = import_module(package)
        print('1 : ' + str(package))
    results = {}
    for loader, name, is_pkg in walk_packages(package.__path__):
        full_name = package.__name__ + '.' + name
        results[name] = import_module(full_name)
        if recursive and is_pkg:
            results.update(import_templates(full_name))
    return results
...

Beer.py

...
from Livraison import Livraison
...

output terminal

templates
1 : <module 'templates' from 'PATH/GestionEmbed/templates/__init__.py'>
templates.Beer
1 : <module 'templates.Beer' from 'PATH/GestionEmbed/templates/Beer/__init__.py'>

Traceback (most recent call last):

    tmp = import_templates("templates")
  File "PATH/GestionEmbed/main.py", line 45, in import_templates
    results.update(import_templates(full_name))
  File "PATH/GestionEmbed/main.py", line 43, in import_templates
    results[name] = import_module(full_name)

  File "PATH/GestionEmbed/templates/Beer/Beer.py", line 7, in <module>
    from Livraison import Livraison
ModuleNotFoundError: No module named 'Livraison'

Thank you in advance if you can help me (and again sorry for my english ^^)

You are running main.py, which imports Beer.py, which tries to import Livraison.py.

The problem is the line in Beer.py which says: from Livraison import Livraison. Python tries to import Livraison based on the position of main.py - so it is like you wrote from Livraison import Livraison in main.py. There is no Livraison.py in the same folder as main.py, so there is an error.

To import based on the position of Beer.py, use:

from .Livraison import Livraison

in Beer.py.

The . means that python imports Livraison based on the position on Beer.py
