Error in Celery: “ModuleNotFoundError: No module named 'tasks'”

Question

When I run the batch file to enable Celery:

python.exe -m celery -A tasks worker.celery -P eventlet -f celery.logs -l info

An error occurs:

ModuleNotFoundError: No module named 'tasks'

I tried to add this path to the sys.path, change the virtual environment, but nothing helped.

The code itself tasks.py

import requests
from requests.auth import HTTPBasicAuth

from celery import Celery


celery_app = Celery('nsi', broker='amqp://guest@localhost//')


@celery_app.task(
    name='sendToNsi',
    default_retry_delay = 4 *(60 * 60),
    max_retries =  1000,
    autoretry_for=(Exception,))

def sendToNsi(NSI_url,answer):

    s=requests.Session()
    post_request = s.post(NSI_url, data=answer,auth=HTTPBasicAuth('__', '___'))
    post_request.raise_for_status()

Maybe the tasks file is not visible from the path you are executing it.

try:

python.exe -m celery worker.celery --app=nsi -P eventlet -f celery.logs -l info
