ml_system.ex:3: Function predict/1 has no local return
ml_system.ex:6: The call 'Elixir.MLSystem':call_model_b(feature@1::number())
will never return since it differs in the 1st argument from the success
typing arguments: (binary())

ml_system.ex:22: Invalid type specification for function
'Elixir.MLSystem':call_model_b/1. The success typing is (binary()) ->
binary()
ml_system.ex:23: Function call_model_b/1 has no local return
ml_system.ex:24: The call 'Elixir.String':upcase(feature@1::number()) will
never return since the success typing is (binary()) -> bitstring() and the
