tips

protoc --go_out=. --go_opt=paths=source_relative \
--go-grpc_out=. --go-grpc_opt=paths=source_relative \
proto/hello_world.proto

windows:

protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative proto/hello_world.proto

python3 -m grpc_tools.protoc -Iproto --python_out=. --grpc_python_out=. proto/hello_world.proto

-Iproto is -I + proto file directory, and the python client import package name is like hello_world_pb2 and hello_world_pb2_grpc your proto file name + _pb2 and + _pb2_grpc
