I have a requirements.txt in my python/django project. Everything has worked fine, locally as well, until I tried to include google-cloud-speech in my requirements and deploying to heroku. It has failed since then and I'm not sure why. (I have deployed to heroku numerous times before this)
I'm following this example here: https://cloud.google.com/speech-to-text/docs/libraries
Test locally, everything compiles and endpoints work correctly with the imports of:
from google.cloud import speech_v1p1beta1
from google.cloud.speech_v1p1beta1 import enums
Steps to reproduce: In my virtualenv
pip install -r requirements.txt
python manage.py runserver [works]
run endpoint for speech transcription [works]
git push heroku master [fails]
Here's the output:

I ended up having to downgrade my versions of grpcio and google-core-api to resolve this. Lots of trial and error so I don't really have a root cause to share unfortunately.
