[bug#59607] [PATCH 0/8] Upscale your anime pictures, now with 99% less malware

[Liliana Marie Prikler]

Hi Guix,

A certain post on This Week in GNOME [1] particular mentioning [2] got
me curious as to what Tencent is up to with their machine learning
stuff.
As it turns out, ncnn is a rather powerful platform that allows running
neural networks on your GPU via Vulkan.  That's right, Vulkan, none of
that CUDA bs.  Sadly, the training part appears to still be done using
good ol' pytorch, so I packaged the python variant as well.  To convert
models from one to the other, you do have to jump through some hoops
via onnx, but ncnn comes with a tool that translates from onnx' format
to theirs, so it should hopefully also be useful in other applications.

In order to keep the Guix package clean, I removed "everything" that
depends on CUDA and also dropped (some/most? of) the bits that download
pretrained models over the aether.  However, I only performed
non-automatic tests with a pretrained model for real-esrgan-ncnn, so
take this with a grain of salt.

Anyway, I hope you have some good, freedom-respecting time with this.

Cheers
