erlang-port-with-python VS PyCall.jl

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/

For point 3 you can use https://github.com/cjdoris/PythonCall.jl or https://github.com/JuliaPy/PyCall.jl (and their respective Python sister packages).

PyCall.jl is really handy. Are there any similar projects for calling Chapel code, or Carbon/zig?

Julia and Python interop should not be a problem at all. Actually Julia has one of the best interops I’ve ever seen, so much that swift copied it. https://github.com/JuliaPy/PyCall.jl

One small note, julia also has great python interop via PyCall.jl

It is possible to call Python from Julia using PyCall. Then to install PyCall, run the command in the Julia REPL.

That said, you can run python modules in Julia. So you can just export your code as a module and then use it in Julia via the PyCall package. short description here github here <— you’d just add the pacakge via the really nice package manager built into julia, but for link for more detailed documentation
