awesome-ocaml VS erlang-port-with-python

I haven't spent enough time with dune to form an opinion (go and cargo are absolutely marvelous though) but a quick search[0] reveals that dune is not the only option.

I think Elixir would be interesting for your usecase.

It's a dynamic, garbage collected language. It's easy to pick up and get going with. As a functional programming language there isn't a lot to learn in the way of language constructs, and you don't even have to do the 'wrestling with the type system' thing that you have to do in compiled functional languages like OCaml.

Its processing 'horsepower' is probably comparable to Python, but it's much better for building low latency things if you want to run something in a bit more of a production use case. This is also improving due to the recent addition of a JIT.

The addition of NX is making Elixir an increasingly interesting place to do ML - write Elixir, have it run on GPU etc. See https://dashbit.co/blog/nx-numerical-elixir-is-now-publicly-...

Python integration is probably best done using the Erlang 'port' system - running Python as a managed process and communicating with it using messages over stdin/stdout. I use it for C interop and it works well (and fits well with the Elixir/Erlang process model). It's not difficult to roll your own in Python e.g. https://github.com/fujimisakari/erlang-port-with-python/blob... or look at something like http://erlport.org/
