Hylang is definitely interesting. I experimented with it an TensorFlow and eventually everything worked OK.
As someone else here mentioned, Python is where most of the deep learning action is. In the end, I settled in using Python for deep learning and use a thin REST service to use my models from Common Lisp or Haskell.
Another approach I used was to convert saved Keras models to something I could import into Racket.
But back to the topic: Hylang is a very cool project and does let you mix Lisp and Python.
