@nileshkokane01 Any update on this?

@amyeroberts I can continue working on it.

Hi @amyeroberts. As I am not the owner of nileshkokane01:interpolate_clip repo, I've done the changes in my forked repo: see PR: https://github.com/huggingface/transformers/pull/31900

Hi @amyeroberts, have you been able to have a look? I can ping someone else if needed. Thanks!

I have included the interpolation of positional embeddings in all the following models, (and their respective tests) in #32600 :

- altclip
- bridgetower
- chineseclip
- clip
- clipseg
- kosmos_2
- x_clip
- git

Waiting for review.

Thanks!

@nileshkokane01 Shall we close this with the opening of #32600? 

@amyeroberts sure!
