add COMET to model-libraries.ts

[zouharvi]

COMET is a very popular machine translation quality estimation framework. However, downloads can't be tracked as of now.

• COMET repo: https://github.com/Unbabel/COMET/
• Example COMET-like models:
  • https://huggingface.co/Unbabel/wmt22-cometkiwi-da
  • https://huggingface.co/zouharvi/COMET-instant-confidence
  • https://huggingface.co/zouharvi/PreCOMET-var

Hi @zouharvi - thanks a lot for your PR! I was wondering if it's possible for you to change the file-name upstream to one of the recognised file-names here: https://huggingface.co/docs/hub/en/models-download-stats#which-are-the-query-files-for-different-libraries

This way the downloads would automatically work for your repos - and this way we don't need another custom download rule for the library.

In anyway - you'd need to make sure that the repos have the COMET tag and show up here: https://huggingface.co/models?other=COMET before the merge (this is the only way downloads would be tracked)

Hi, thanks for reply. My repos are following the file layout as needed by the COMET library (https://github.com/Unbabel/COMET/), so I can't change them.

I didn't add the COMET tag because the library is not being tracked yet.

LGTM!

As mentioned by @Vaibhavs10 , we prefer to have at least a few models listed under https://huggingface.co/models?other=comet before making it official. You simply have to add library_name: comet to the modelcard metadata (or under tags if repo already have a library_name).

@zouharvi Would you mind updating your model cards and opening a few PRs on main COMET repos to add this metadata? That is a very good opportunity to make sure COMET models are easily discoverable on the Hub!

Here is an example PR I've opened in the past to a repo I didn't own in order to add library_name: https://huggingface.co/MCG-NJU/VFIMamba_S/discussions/1. It's usually good to provide context and link to this PR so that the repo owner understand why the change is needed :)

Thanks! Added for my models: https://huggingface.co/models?other=comet

And opened a PR for two of the most popular original COMETs:

• https://huggingface.co/Unbabel/wmt22-comet-da/discussions/4
• https://huggingface.co/Unbabel/wmt22-cometkiwi-da/discussions/10

Perfect, thanks! I'll merge once the lint CI is green :)
Expect a 3-4 days before having it live on production.
