Ask HN: PyTorch on AMD APU for laptops?

Hello,

Can anyone here run PyTorch on ROCm with an AMD APU on a laptop? If so, what is the brand/model of your laptop? How is the performance?

From a quick research online, it looks like this should be possible, but there are a lot of pitfalls.

See here: https://community.amd.com/t5/knowledge-base/amd-rocm-hardware-and-software-support-document/ta-p/489937

> The integrated GPUs in AMD APUs are not officially supported targets for ROCm. As described [below](#limited-support), "Carrizo", "Bristol Ridge", and "Raven Ridge" APUs are enabled in our upstream drivers and the ROCm OpenCL runtime.

> However, they are not enabled in the HIP runtime, and may not work due to motherboard or OEM hardware limitations.

> As such, they are not yet officially supported targets for ROCm.

In summary, it is possible to use AMD APUs (at least the desktop versions) for machine learning with PyTorch and ROCm, but it needs a bios which is properly built, which apparently is hard to find…

I need a very portable solution to do ML with PyTorch, and small laptops with Ryzen APUs look like a good solution, but I’d like to make sure before I invest my money in that.
