Populate() isn't reentrant Django Google App Engine

I'm ruing google app engine, python 2.7, and importing Django 1.8. After pulling in python-firebase (-e git://github.com/ozgur/python-firebase.git#egg=python-firebase), I get the following error

Traceback (most recent call last):
  File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 240, in Handle

  RuntimeError: populate() isn't reentrant

Many of the other solutions have suggested to alter the wsgi.py file, because django gets installed right before deployment in the requirements.txt file.

Ultimately this leads to the server stating: "Error: Server Error The server encountered an error and could not complete your request. Please try again in 30 seconds." How can I resolve this?
