and the use of a grpc client using the interface specified in `model.proto`. An
example client is provided in `client.py`. To use the client you need to
generate code with with the grpc protobuf compiler as follows: 
`python -m grpc_tools.protoc -I. --python_out=. --grpc_python_out=. model.proto`
For more details, see https://grpc.io/docs/languages/python/quickstart/.

Also included is a requirements.txt to document the used python packages.
