芹菜工人不啓動一個應用程序的ImportError

Question

我想與redis的django一起使用芹菜作爲經紀人。我的應用程序名稱之一是用戶，其模型是由其他應用程序導入的。當我運行django服務器時，它啓動時沒有任何錯誤，一切正常。

但是，當我嘗試啓動命令「芹菜-A項目工人-l INFO」芹菜工作者，我得到以下錯誤：

    from user.models import * 
ImportError: No module named models 

這裏要注意的事情是，它說沒有模塊名爲模型和不是沒有模塊名爲user.models。這可能意味着與其他文件存在一些衝突，儘管我已經進行了雙重檢查，並且項目目錄或app1目錄中沒有user.py。如果我將應用程序「user」重命名爲「user2」，則工作人員啓動。另外值得注意的是芹菜在某個時候開始很好的事實。從那時起，代碼已經改變，但沒有添加應用程序。

我的項目具有以下結構（只顯示相關部分）

- project 
    - project 
    - celery.py 
    - models.py 
    - user 
    - models.py 
    - app1 
    - models.py 
    - tasks.py 

和celery.py是

from __future__ import absolute_import 

import os 
from celery import Celery 
from django.conf import settings 

# set the default Django settings module for the 'celery' program. 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings') 

app = Celery('project') 

# Using a string here means the worker will not have to 
# pickle the object when using Windows. 
app.config_from_object('django.conf:settings') 
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS) 

芹菜配置是

BROKER_URL = 'redis://localhost:6379/0' 
CELERY_ACCEPT_CONTENT = ['json'] 
CELERY_TASK_SERIALIZER = 'json' 
CELERY_RESULT_SERIALIZER = 'json' 

感謝

問題是一個命名空間衝突。由於python 2.x中包含user配置掛鉤，並且已在python 3內刪除該配置掛鉤。有關user的更多信息：
