Since deta model does not have vision

test can be done by

from transformers import DetaForObjectDetection

model = DetaForObjectDetection.from_pretrained("jozhang97/deta-swin-large")

model.model.freeze_backbone()

@amyeroberts Can you confirm this modification?

[ArthurZucker]

Thanks! Left a few nits for now 😉

@ArthurZucker Hi Arthur, can you review this test case modification for DETA? a583fa7
Because I do not fully understand CircleCI when this testing function will be called in transformers
Now I think I understand the CI piplines.

[ArthurZucker]

Thanks you!

For the last CI you need to run make style with ruff==0.1.5

[SangbumChoi]

root@9603895c7c37:/mnt/nas2/users/sbchoi/transformers# make style

running make style doesn't change anything, and the last CI seems irrelevant to this PR.

Would reformat: src/transformers/models/bloom/modeling_bloom.py
Would reformat: src/transformers/models/fuyu/image_processing_fuyu.py
Would reformat: src/transformers/models/mpt/modeling_mpt.py
3 files would be reformatted, 2416 files left unchanged

Exited with code exit status 1

did I missed something?

It's alright just revert the changes and we'll be alright

[SangbumChoi]

@ArthurZucker Done by just syncing the fork of my original repo!
