403 link served on torch index url

🐛 Bug

Hi 👋

pip install torch torchmetrics~=1.0.0 --extra-index-url https://download.pytorch.org/whl/cu118

Will attempt to download torchmetrics 1.0.3 from the torch index:
https://download.pytorch.org/whl/torchmetrics

The link hosted there will respond with 403 forbidden.

Could you remove that link?

Many thanks!

Hi! thanks for your contribution!, great first issue!

Hello, I think the the problem is using --extra-index-url so you shall use --find-links so your command will be:

apt update && \
apt install python3.7 python3-pip -y && \
pip3 install --upgrade pip && \
python3.7 -m pip install pytorch-lightning \
	--find-links=https://download.pytorch.org/whl/cu113/

Hi @Borda, torch deprecated --find-links, also the official installation page now references --index-url / --extra-index-url.

--find-links still works if you point to a html page that contains <a> html tags pointing directly to wheels, so that would be

pip install torch torchvision \
  --find-links https://download.pytorch.org/whl/cu113/torch/ \
  --find-links https://download.pytorch.org/whl/cu113/torchvision/

Since they now host a PyPI index, installation options for end users have become more flexible. See for instance discussions at ray-project/ray#26072

The culprit link hosted on the torch index is https://download.pytorch.org/whl/torchmetrics-1.0.3-py3-none-any.whl

which will be preferred over torchmetrics 1.0.3 hosted on official PyPI, regardless wether the torch index is specified under --index-url or --extra-index-url.

Do you have the capability to get that link removed from the torch index?

We do not have any power over this index, please follow on official PyTorch issue... :(
