Fix Swinv2ForImageClassification NaN output
Author: miguelm-almeida
Pull request: yes

# What does this PR do?

To address the issue of NaN logit outputs for certain combinations of the `image_size`, `patch_size` and `depths` configuration parameters, an assertion was made to ensure that the resulting `window_size` field in the model's Self Attention class is greater than 1, preventing divisions by zero in the normalization of `relative_coords_table`.

Fixes: #28675

Hi,

Thanks for your PR! Could you run `make fixup` so that the CI will be green? Thanks!

Hi @NielsRogge !

I've been running through this error while running `make fixup`:

![image](https://github.com/huggingface/transformers/assets/110698619/45ca4ed1-e2b9-4ee7-892b-0b0b0a8fbd4a)

The files under `src/transformers/models/auto` are all being modified when I run this command and this error keeps going even when I change everything back.

As I am developing on windows, I have made sure that I set `git config core.autocrlf=input`, but can this be related to a LF-CRLF conversion? (It's the only thing I can think of, as these files are now marked as modified but I see no changes in the code whatsoever)

Thank you!


I have also run the `make fix-copies` command as suggested by the CI log:

![image](https://github.com/huggingface/transformers/assets/110698619/881e608f-9601-42ac-ae2e-33ccae4b2838)

This runs fine but the `make fixup` comes back to the same error after I run it. 
I have also not altered any code regarding `test_modeling_qwen2_moe.py` so I don't know what can be causing this issue.

Rebasing on main should fix this issue

@miguelm-almeida easiest is to do this:
```
git remote add upstream https://github.com/huggingface/transformers.git
git fetch upstream
git merge upstream/main
```

Got it, thank you all!
