Start the inference server. This serves the gRPC server running at port 8085 and http server running at 8080

$ python start_runtime.py

Start the client the sends text inputs to gRPC and http (Note: I am facing issue with http not responding with predictions). I tried cloning the caikit repository and tried to run the example directly and http is responding withe predictions correctly. So the issue is something to do with the way that I am trying to reproduce the example.

✗ python client.py 
Text:  I am not feeling well today
Response from gRPC:  classes {
  class_name: "NEGATIVE"
  conf: 0.99970537424087524
}

Text:  Today is a nice sunny day
Response from gRPC:  classes {
  class_name: "POSITIVE"
  conf: 0.999869704246521
}

Text: I am not feeling well today
RESPONSE from HTTP: {
    "detail": "Not Found"
}

Text: Today is a nice sunny day
RESPONSE from HTTP: {
    "detail": "Not Found"
}
