Ok, to be honest, I haven’t gotten to this part of the course yet but I heard that Swift for Tensorflow may become a huge part of fastai in the future.
AMD has it’s ROCm TensorFlow port (up to date with latest TF 1.14), but MacOS GPU is not listed there.
Linux GPU should work and i know companies that use AMD Radeon VII (16GiB memory) in their machines and it works with TensorFlow! (no licence restriction from AMD to use only expensive GPU in servers)
I would definitely support more competition in the deep learning GPU space. If the goal is to make deep learning more available to a wider audience, cost is still an important factor and if we can bring that down by getting AMD into the space, I’m all for it.
