Not sure where do I report this but as per the topic suggest, the Start Locally | PyTorch 2 gives the wrong install instruction if used without user interaction (default).
As of now, without user interaction (default), the install instruction is:
conda install pytorch torchvision cudatoolkit=9.2 -c pytorch -c defaults -c numba/label/dev
for CUDA 10.0. However, when the user clicks on CUDA 10.0, it then proceeds to give the correct install instruction, so this is just some initialization problem.
