Proget Python connector to PyTorch Cuda Index

m.karing_2439

Hello,

PyTorch is using some specific index for CUDA-enabled versions of PyTorch. This is detailed here: https://pytorch.org/get-started/locally/

I'm trying to access the index https://download.pytorch.org/whl/cu118
Using it directly in pip for installing the package works just fine. Adding this index as a PyPi conenctor to ProGet does not work at all. The health check for a connector to this index always returns the following in the health check:

Connector PyTorch-cuda118 health check reported error: The remote server returned an error: (403) Forbidden.

I setup the connector the following way:

Type: PyPI
Name: PyTorch-cuda118
Url: https://download.pytorch.org/whl/cu118
Timeout: 10sec
Authentication: anonymous
Advanced option: Allow searching and listing in the PyPi repository

Metadata caching, as well as package filters are disabled.

Am I doing anything specifically wrong?

Best regards,
Martin

Hi @m-karing_2439 ,

Unfortunately, this repository doesn't following PyPI repository conventions.

For example:

No way to see latest packages (should be https://download.pytorch.org/whl/cu118/rss/updates.xml)
Does not return anything for /simple listing (e.g. https://download.pytorch.org/whl/cu118/simple)
Does not support JSON-based API to retrieve package metatadata

I guess it "happens to work" in pip , or perhaps they install a plugin that allows it to work... but ProGet is designed around PyPi repository specs. which is why a non-confirming download site won't work very well.
I'll add a note to investigate this further, but for the time being you should just download the wheels and upload them to a feed in ProGet.

Cheers,
Alana

Hello @atripp,

well that is a bummer. Thank you for looking into it anyway.

Best regards,

Good news @m-karing_2439 ,

This works in ProGet 2024! More specifically, when rewriting/refactoring the PyPi feed, we added support for this "unconventional" repository - specifically, one that doesn't follow the /simple convention or use any of the JSON/warehouse api.

Cheers,
