Thanks a bunch! From the accelerate side this looks fine; do you want to do big model inference while you're at it? (if not all good).

I assume accelerate test etc went well? 🤗

@muellerzr I forgot to mark it as a draft 😅.
I'm still debugging some issues, both from accelerate and optimum-habana side, should be ready by next week.
