I'm not an ML expert so can't tell how good any of these are but there seem to be enough ML-related stuff for Ruby. There are a few tensorflow bindings for Ruby. There's torch.rb. There's numo, kinda like numpy. SciRuby lists a bunch of AI-related/numeric gems. What I'm trying to say is there's no reason to expect Python parity because there's Python and no reason to divert the effort but ML is not quite non-existent in Ruby. Start using it and be the change you want to see in the world.
