Hi @ptrblck, I tried both of these options to set USE_NNPACK=0, but still got the error message as in the title.
For the first option, I did
USE_NNPACK=0 pip3 install --pre torch torchvision torchaudio -f https://download.pytorch.org/whl/nightly/cu111/torch_nightly.html

to install the latest nightly package; for the second, I added
export USE_NNPACK=0;

to right before my previous command.
Is this behavior expected? Thanks!
(This error comes right after the UserWarning that I should use torch.linalg.qr instead of torch.qr. Is it related to the error here?)
