$ ./manage.py migrate 

これらのステップに続いて

は

私requirements.txt

celery==4.0.2 
django-celery-beat==1.0.1 
django-celery-monitor==1.1.0 
django-celery-results==1.0.1 

の関連する部分であり、ここでINSTALLED_APPS

で私をあります

INSTALLED_APPS = (
    'modeltranslation', 
    ... 
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes',

    'django_celery_monitor', 
    ... 
) 

は私が

$ ./manage.py migrate django_celery_monitor # also tried for _results and _beat 

を実行しようとしましたが、それは同じエラーをスローします。
