That’s wrong, as we are building PyTorch with CUDA11.5 and you can also download the nightly binaries with CUDA11.5 e.g. via:
pip3 install --pre torch -f https://download.pytorch.org/whl/nightly/cu115/torch_nightly.html

so I don’t know where this information is coming from.
EDIT: I was wrong, as 1.10.0 was cut before the 11.5 release (and 1.10.1 is a bug fix release) so you would need to use the latest nightly or install the wheels).
