Call gRPC Client Stub from External Django Application

I'm following https://blog.codeship.com/using-grpc-in-python/ to use gRPC with Python. Has anyone used the client wrapper (client_wrapper.py ) with an external Django application? I need a way to call the client or client wrapper from an external Django application and obtain a stub to make the RPC calls. Is this possible? Any help would be appreciated. Thanks.
