Thanks. That worked. However, when I run my testfile.py I get the following
error:
[localhost git]$ python testfile.py
Traceback (most recent call last):
File "testfile.py", line 4, in <module>

line 50, in <module>
from google.protobuf.pyext import _message
ImportError: cannot import name _message
>From the descriptor.py file here is where it fails:
if api_implementation.Version() == 2:
from google.protobuf.pyext import _message
else:
from google.protobuf.internal import cpp_message
Also, before I ran my file I export the following environment variables per
README file in the python folder.
$ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp
$ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION_VERSION=2
