As an old Lisp user, I am impressed by Flux (which I started using this weekend, after someone on HN recommended Flux to me) as transforming Julia, like building Lisp up to a new language for whatever problem you are working. I also appreciate how incredibly easy it was to get started with Flux which ‘just worked’ with CUDA 10 and the GPU in my laptop and the model zoo was great to get started. Really quality stuff!

Hah, that someone was me, I'm glad it clicked for you! I had a similar experience of it "just working" when trying a few weeks ago. I particularly enjoyed being able to build and run Flux models interactively just like any other julia code. Also, having a hand written loss function just run on the GPU with no extra effort kind of blew my mind.

How "ready" is Flux, for building something like Rasa?

I think your major problem is going to be orchestration, which is not easy to solve.

My feeling is that Flux is a fantastic tool for playing with innovative models which can't be expressed in the usual frameworks. And quite possibly already the best thing that exists for open ended experimentation in ML.

On the other hand, for training and deploying models which are easily expressed in other frameworks you will find a lot more ready made pieces of infrastructure elsewhere.

Thanks!
