Good to see the vita is still getting some love :)
No because this uses CUDA which is nvidia only. Only hope would be if they switched to vulkan instead but its probably not going to happen plus itd be super slow on mobile
This uses the cuda api so it wont work on Macos until another api like opencl or vulkan is added. For now its windows+nvidia only thanks to cuda
it supports cuda so yes https://www.videogames.ai/2019/01/18/P106-100-GPU-Machine-Learning.html
