Scripts != "dev" language. Between lack of static types (mypy is an improvement but compared to typescript-ish annotations in VS code...) and the packaging state we are in you are quite forced to have one virtualenv per key functionnality/magic library dependency. So my guess is... be prepared to use any "simple" web service (flask?) and wrap your magic library dependencies as pseudo webservices in their own virtualenv if not docker/gpu-docker containers. Multithreading is a failure anyway (might get better with per thread interpreter support in 3.8+). Less exciting than the promises of the past but at least "kubernetes+virtualenvs+web services" will work and be testable. Or just use javascript/scala/ocaml/go/erlang/elixir/... + c++/cuda/opencl (real platforms) ;-)
