Unable to Swagger API docs via viper-web

[Dhatheway]

After following the install instructions I am able to get everythign up and running, but when I click More-> API Docs I get a 500 page and the following error:

`2019-07-12 15:56:14 - django.request - ERROR - log.py:228 - Internal Server Error: /api/v3/docs/

The above exception was the direct cause of the following exception:

Hm.. I just checked on my dev system and where SwaggerUI works. Can you try to locate the base.html on your system? Maybe the path is off?

$ `locate rest_framework_swagger/base.html`

venv/lib/python3.6/site-packages/rest_framework_swagger/templates/rest_framework_swagger/base.html

Which version of django-rest-swagger did you install?

$ pip freeze | grep swagger
django-rest-swagger==2.2.0

[Dhatheway]

Something appears off for sure I searched for "rest_framework_swagger/base.html" with no results, but when I searched for "base.html" I see my path is in-fact different "/usr/local/lib/python3.6/dist-packages/rest_framework/templates/rest_framework/base.html". In terms of "django-rest-swagger" we are the same.

$ pip3 freeze | grep swagger
django-rest-swagger==2.2.0

[Dhatheway]

Went ahead and updated the path in "viper/web/viperweb/templates/rest_framework_swagger/index.html" from "{% extends "rest_framework_swagger/base.html" %}" to "{% extends "rest_framework/base.html" %}" which allows the doc page to load but it just says:

GET /api/v3/docs/
HTTP 200 OK

Reset my test vm and followed the install instructions here https://viper-framework.readthedocs.io/en/latest/installation/index.html and still running into the same issue.

$ locate base.html
/home/daniel/viper/viper/web/viperweb/templates/base.html
/usr/local/lib/python3.6/dist-packages/coreschema/templates/base.html
/usr/local/lib/python3.6/dist-packages/django/contrib/admin/templates/admin/base.html

I am facing the same issue as the previous poster, same Ubuntu version, newly set up in a virtual machine.
