I’m using a custom dataset to retrain(fine-tune) the DETR model. After Augmenting and preprocessing my images using `image_processor = AutoImageProcessor.from_pretrained(checkpoint)` I get this errror `ValueError: too many values to unpack (expected 3)` when I run `trainer.train()`. Please what could be the cause of this
