Supervising Python processes from Elixir

My Elixir project must rely on PyWaves, a Python library, to execute trades. Erlport and Pyrlang looked like attractive solutions for reliable connectivity between the two but, after further inspection, it appears both projects have been abandoned.

gRPC seems to be a viable alternative but before going down that rabbit hole I have to ask, are there any actively maintained libraries that offer simple, featherweight, direct solutions to establishing, maintaining and monitoring communications between Elixir and Python codebases running on the same machine?
