Cannot import name 'deepspeed_reinit' from 'transformers.deepspeed'
### System Info

Bug found when following the optimization steps provided in **https://huggingface.co/blog/optimum-inference.** 

It seems like transformers/deepspeed.py does not contain the method '**deepspeed_reinit**' so it's not possible to import it when loading ORTModel objects. 

Thanks in advance for your incredible work.  @stas00, @pacman100

Hi @rubenCrayon!
`deepspeed_reinit` was removed a few versions ago, you should use a more recent version of Optimum. Which may requires to change your script a bit, in that case I recommend that you open an issue in Optimum: https://github.com/huggingface/optimum/issues<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.
