I am trying to mix Elixir with Python using ErlPort, so I decided to read some tutorials about it and the documentation related about everything involved. I understand how works the logic and what does each function. However, I am having problems casting a message and receiving the Python response.

Based on what I read and what I have done I understand that when I cast a message with cast_count/1, this is handle by handle_cast/2 and then is handle by the Python function handle_message() and then this one cast the message with the function cast_message() and the imported one cast()from erlport.erlang. Finally, Elixir should handle the message received from Python with handle_info/2. I think this function is not being executed but I don't know the reason, although I have investigated a lot this stuff in different sources and in the documentation of GenServer and ErlPort.

In my case I have the next structure: lib/python_helper.ex to make ErlPort works and lib/server.ex to call and cast the Python functions.
