You have a few options for this: The TH package wraps Blas, etc., and has MINST, GAN, etc. examples.

My preference is using py4cl to use pre-trained TensorFlow models in Common Lisp.

I wrote a short book on Hy that has some deep learning examples, but I don't use Hy that often any longer. I am looking forward to the 1.0 changes.
