I installed PyTorch with
pip3 install --pre torch torchvision torchaudio -f https://download.pytorch.org/whl/nightly/cu110/torch_nightly.html

And then in a Python session I ran:
import torch
torch.tensor(1).cuda()

which then raised the warning in the title.
I know this supposedly works for people with CUDA 11.1 (while I’m on 11.0) but before I ruin my life by trying to upgrade my CUDA I thought I’d check here to make sure I’m not missing anything else.
