TaskState is already registered

[Felipe Tartarotti]

Hi, when I try to migrate after add djcelery to my INTALLED_APPS I got this error.
Does anyone know why ?

File "C:\Users\Tartarotti\AppData\Local\Programs\Python\Python37-32\lib\site-packages\djcelery\admin.py", line 243, in
admin.site.register(TaskState, TaskMonitor)
File "C:\Users\Tartarotti\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\contrib\admin\sites.py", line 109, in register
raise AlreadyRegistered('The model %s is already registered' % model.name)
django.contrib.admin.sites.AlreadyRegistered: The model TaskState is already registered
