What does this PR do?

jpelhaw not exist on hub, and test fails at this moment.

Run locally with this PR: doctest pass for this model now.

The documentation is not available anymore as the PR was closed or merged.

LGTM if tests work locally that's an awesome quick fix

Thanks for the fix. Out of curiosity was it a typo or did the user rename their account?

(Thinking that while it's good to foster community to rely on individuals checkpoints for documentation, it's not the most strategic thing to avoid sudden breaks.)

[ydshieh]

Checked with the last run (May 18th -- sorry I should check doctest status much earlier), it worked with the previous checkpoint string, which suggests that the user renamed since then.

I agree with you regarding not the most strategic thing (I raised the doubt before, but we decided to continue with this approach to see how things go)

@LysandreJik just reminded me that the migration to the new cache system on huggingface_hub will magically support repo renames so this won't be a problem in the future!
