Could you point to one canonical checkpoint on the Hub as well?

Thanks, I added a reference to facebook/xlm-v-base :)

CI is failing, I'm going to read the Flan-T5 PR (#19892) to see how it should be done! |
|
You just need to add the model type (same as what you picked for the page in the doc) and name in the configuration_auto file. The PR you mention also does it :-) |
|
Failures are unrelated to this PR so merging! |

Hi,
as discussed in #21330 it would be good to have an extra entry for the new XLM-V model in the Model Doc.
This PR adds it with some additional information about the model and conducted experiments with it.
