🐛 Describe the bug

Virgin install on Raspberry Pi 4.0 8gb

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu
python3 -c "import torch;print(torch.__version__)"

results in:
Illegal instruction. and a core dump (on Ubuntu) and fails on the basic 64 Raspberry Pi Debian based OS...

HOWEVER:

Ignoring the installation instructions on https://pytorch.org/, and instead installing with:

pip3 install https://download.pytorch.org/whl/torch-2.0.0-cp310-cp310-manylinux2014_aarch64.whl

results in version of torch 2.0.0 that will work on the Raspberry Pi 4

Versions

executing:

wget https://raw.githubusercontent.com/pytorch/pytorch/master/torch/utils/collect_env.py
# For security purposes, please check the contents of collect_env.py before running it.
python collect_env.py

also results in Illegal instruction

(further - uninstalling torch 2.0.0 and attempting to install 1.13.1 per the instructions on https://pytorch.org/get-started/previous-versions/ i.e.

pip install torch==1.13.1+cpu torchvision==0.14.1+cpu torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cpu

results in

ERROR: Could not find a version that satisfies the requirement torch==1.13.1+cpu
ERROR: No matching distribution found for torch==1.13.1+cpu

that said an install of the form:

pip install torch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cpu

works a treat and

python3 -c "import torch;print(torch.__version__);print(torch.rand(3))"

returns what is expected:

1.13.1
tensor([0.1033, 0.6867, 0.4403])

python collect_env.py against the 1.13.1 works and returns:
