I use:
Python 2.7

And i have this problem:

Hi, you don't need to include rest_pandas in your INSTALLED_APPS - just import the necessary views, etc. as needed.

Thank you for explanation!

I've also submitted a patch to DRF core that will fix this issue even if rest_pandas is in your INSTALLED_APPS. See encode/django-rest-framework#3785.
