PyTorch nightly with support for ROCm 5.5 and gfx1100 is available

ROCm/ROCm#1880 (comment)

PyTorch nightly wheels with ROCm5.5 and Navi31 (gfx1100) support are available now:
pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/rocm5.5

However, HSA_OVERRIDE_GFX_VERSION=10.3.0 doesn't work with Navi31, and 11.0.0 is used if it's required, so the current impl of Automatic doesn't work out of the box.

The rocminfo output on my end:
