Protocol Buffers To Pass Data Between Elixir/Phoenix And Python

This article is an extension to my previous article titled — “Using Python Trained Machine Learning Models from Phoenix (Elixir) Applications”. In my previous article, I showed how to use python trained machined learning models from Elixir applications using ErlPort. However, the model parameters passed from Phoenix (Elixir) app to make prediction using Python code was a simple list data-type and it was supported by built in data-type mappings of ErlPort.
