Below error is coming while running the colab file of zero-shot-object-detection-with-grounding-dino.ipynb in Google COLAB
from last few days, it was not there before.

FutureWarning: The device argument is deprecated and will be removed in v5 of Transformers.
UserWarning: torch.utils.checkpoint: the use_reentrant parameter should be passed explicitly. In version 2.5 we will raise an exception if use_reentrant is not passed. use_reentrant=False is recommended, but if you need to preserve the current default behavior, you can pass use_reentrant=True. Refer to docs for more details on the differences between the two variants.
UserWarning: None of the inputs have requires_grad=True. Gradients will be None

Are you willing to submit a PR?

• Yes I'd like to help by submitting a PR!

Start with zero-shot-object-detection-with-grounding-dino.ipynb in Google Colab and reproduce the failure. Inspect /content/GroundingDINO/groundingdino/models/GroundingDINO/ms_deform_attn.py around line 53, where _C.ms_deform_attn_forward is called; done means the notebook's prediction step completes without the NameError.
