[Rocketknight1]

We're also getting lots of CI failures because all of the processor tests for SmolVLM depend on num2words!

[zucchini-nlp]

Sorry, didn't notice it would fail. Actually the package is used only when chatting with video, so we might raise error only when num2words is actually called. And guard video chat template tests with num2-word_available. WDYT?

[gante]

@zucchini-nlp at the end of the day, would fail too: either we have no tests for the feature, or we need to push the new requirement :D

I'm leaving that part of the logic changes to you 🤗 And I agree, the check should only exist where it is strictly needed

Yep, we can later raise error only when video code is called. But making num2words a requirements means users won't have a problem with the import error at all now :)
