Use boto3 for GAE for Python

Question

I am trying to use boto3 for the Polly API in the Google App Engine for Python. So far I have installed boto3 in my lib subdirectory

pip install -t lib boto3

When I run a stand-alone script, it works well. But when I execute boto3.client (...) in my application on my DEV server, I get the error botocore / session.py:

from _winreg import OpenKeyEx, QueryValueEx, CloseKey, HKEY_LOCAL_MACHINE
ImportError: No module named _winreg

I saw that since GAE is sandboxed, so it’s normal that the _winreg module is unavailable

Does anyone have any experience installing boto3 in GAE and running it on a DEV and PROD server?

Or is there another way to use the Polly API?

As @ simon-pierre pointed out below the _winreg error, you can solve it by editing config_appengine.py and adding:

import sys
sys.plateform='linux3'

But then I ran another issue

Python NameError: 'ssl' . , app.yaml ssl :

libraries:
- name: ssl
  version: 2.7.11

, GAE Windows: _ssl RAND_egd ImportError: RAND_egd. sochet.py
