That's what I had in mind, as well. (I think debian-science should also
be CCed as most consumers of accelerated computing are bound to be on
that list).

I'll take a look, thanks.

Like anyone else needing pytorch.

The simple fact of the matter is that Debian users who own an Nvidia
card and need pytorch (or pure CUDA, as I have)
  (1) will already have the Nvidia driver and CUDA installed anyway, and
  (2) will then simply pip install or conda install pytorch, rather than
      use the non-CUDA version from our archive.

So if the Project rejects extending support for CUDA, not only would
that have absolutely zero effect on CUDA use, it would actually also
torpedo our own version of pytorch. That's hardly sensible.
