grpc with python client connect to the cpp sever failed
I try to realize the python call c++ by grpc, in client use the python and sever is c++, c++ is correct, but when I run ‘python3 client.py’ is raise error details = “failed to connect to all addresses; last error: UNKNOWN: ipv4:127.0.0.1:50004: Failed to connect to remote host: connect: Connection refused (111)”.
