I don't know in this particular case, but somewhat analogously: Very few people in their right minds do deep learning on CPUs. Yet, I'm extremely happy that PyTorch is in Debian (thanks to the hard work of Mo Zhou!), even if it's CPU-only. It means that I can develop and test-run code on my machine using just Debian packages, before shipping it off to the actual compute infrastructure where GPUs do the heavy lifting on a GPU-enabled non-Debian PyTorch. I can imagine that there are people who do the same with lacking SIMD instructions. Best, Gard
