With nvidea not supporting MacOS beyond the current version, and Google pushing Swift for Tensorflow, I assume both Apple and Google have an increasing incentive to improve the adaptation of AMD GPUs for deep learing.
I've never heard of this (and I do deep learning and use Macs). Do you have a reference?
`tensorflow-rocm` assumes Linux/ROCm, and the ROC (Radeon Open Compute) stuff builds Linux kernel extensions (rocm-dkms).
I don't have big hopes for the project.
Kitura last commit was on June 2018.
And even with all that support, it is not possible to write OS independent Swift without kludges (import darwin vs glibc, really?).
Also many enterprises impose Windows desktops, so none of their dev divisions would even consider Tensorflows's Swift variant, regardless how well it would be doing on GNU/Linux.
