Erro when I to try to use import - python-3.x

Question

I am coding an application that has 2 services integrated with rabbitmq(publisher and consumer).
I have a folder lib that contains a class manager_mq, that is used to manage the process of pub/sub of my application.
My structured the directory to be like the image:
In my consumer or publisher .py file, When I try to import manager_mq an error is returned.
My import to be like that:
from services.lib.manager_mq import Manager
However, an error is returned on the console.
Traceback (most recent call last):
File "consumer.py", line 5, in <module>
from services.lib.manager_mq import Manager
ModuleNotFoundError: No module named 'services'
I am tried to use relative import but the error occurs yet.
Traceback (most recent call last):
File "consumer.py", line 5, in <module>
from ..lib.manager_mq import Manager
ImportError: attempted relative import with no known parent package
How can I solve this problem?

Answer 1

Here both absolute and relative imports won't work. For more information, check out Importing from Parent Directory.
In this case it would probably be the easiest to use sys.path to add the lib to the path.
application
├── consumer
│ └── __init__.py
│ └── consumer.py
└── lib
└── __init__.py
└── manager_mq.py
manager_mq.py test code:
class Manager:
def __init__(self) -> None:
print('test')
consumer.py test code:
import sys
sys.path.append("../lib")
from manager_mq import Manager
m = Manager()
