HF Hub download

[LysandreJik]

Offer an additional method hf_hub_download to bypass the call of hf_hub_url followed by cached_download

[osanseviero]

This is great and very useful! Thanks!

lgtm

is the method name the "right" one? I feel like it works, but was wondering if maybe the more explicit cached_download_from_hf_hub was more explicit

Thoughts?

I feel like hf_hub_download is really the better name here

I feel like it works, but was wondering if maybe the more explicit cached_download_from_hf_hub was more explicit

It is indeed more explicit but I feel that it's a mouthful to say the same thing.

We don't mention cache everywhere in downloading methods (snapshot_download, from_pretrained etc) and yet I think everyone knows it's cached.

sounds good :)
