Which version of gRPC is being used?

I believe I have 1.12.0

Requirement already satisfied: grpcio in /home/pi/env/lib/python3.7/site-packages (1.24.1) Requirement already satisfied: six>=1.5.2 in /home/pi/env/lib/python3.7/site-packages (from grpcio) (1.12.0)

Looking at the message, I think your version of gRPC is 1.24.1
