@echarlaix I pin transformers<4.35 version as workaround for incompatibility issues to be able pass ci checks (removing SSDP, refactoring models that lead to previously used patching approach does not work anymore for llama, opt, and other models).
Is there any plans to fix these issues and alignment with optimum package?

@echarlaix @helena-intel could we prioritize this PR? We need it very much. It will simplify using OpenVINO for Whisper a lot :)

[echarlaix]

very nice PR @eaidova, thanks!

@echarlaix looks like transformers 4.36 break some model export, including whisper support. I added workaround similar to huggingface/optimum#1590, please take a look
