The docs state that Django Rest Framework works with Django versions 1.11, 2.0, 2.1, although the process_request() method of CSRFCheck was actually introduced in Django 1.11.6

The version of Django you're using (1.10.3) is too old for your version of Django Rest Framework.

You should upgrade Django to version 1.11.6 or ideally higher.

pip install --upgrade django  # Upgrade to the latest Django version

or

pip install --upgrade django==1.11.6  # Upgrade to version 1.11.6
