brew install protobuf
pipenv install "grpclib[protobuf]"
pipenv install grpcio grpc-tools
pipenv run python -m grpc_tools.protoc -I. --python_out=. --grpclib_python_out=. helloworld/helloworld.proto

In PyCharm try to mark examples directory as a sources root:
https://www.jetbrains.com/help/pycharm/configuring-project-structure.html#mark-dir-project-view

To run these examples you can follow these steps:
https://github.com/vmagamedov/grpclib/blob/master/examples/README.rst
(examples directory should be in the import paths)

This is relevant for grpclib project structure, you should do similar steps for your project structure.

In addition, I found that setting protobuf=3.20.1 seems to work, does it not support version 4 series?

[vmagamedov]

grpclib supports protobuf>=3.15.0, including 4 series

[jet10000]

I followed the tutorial step by step. The 4 series seems to be invalid, I don't know what I missed, and it is normal to modify it to 3 series.

[vmagamedov]

What "invalid" means? Do you have an error? How can I reproduce it?

helloworld is a package but you're trying to run it's server.py module as a script. That's why relative imports doesn't work.

Try:

$ python -m helloworld.server
