position_ids keys when loading OwlViT models#44508KartikPawade wants to merge 2 commits intohuggingface:mainfrom
Conversation
Older OwlViT checkpoints saved `position_ids` as buffers in the text and vision embedding modules. These tensors are simple integer ranges and are now recomputed dynamically during initialization. This results in `UNEXPECTED` key warnings when loading models such as `google/owlvit-base-patch32`. Add the corresponding patterns to `_keys_to_ignore_on_load_unexpected` to suppress these warnings.

What does this PR do?
Older OwlViT checkpoints stored
position_idsas buffers in the text and vision embedding modules. These tensors are simple integer ranges (0 → max sequence length) and are now recomputed dynamically during initialization.As a result, when loading models such as
google/owlvit-base-patch32, the loader reports the following unexpected keys:owlvit.text_model.embeddings.position_idsowlvit.vision_model.embeddings.position_idsThese buffers are not required for correct model behavior and can be safely ignored.
This PR suppresses the warnings by adding the corresponding patterns to
_keys_to_ignore_on_load_unexpectedinOwlViTPreTrainedModel.This change does not affect model performance or weights and only prevents unnecessary loading warnings when using older checkpoints.
Fixes #44493
