When does this happen?

IF AutoProcessor.from_pretrained fails with ValueError: Unrecognized image processor when loading Qwen2.5-VL models (e.g., Qwen/Qwen2.5-VL-3B-Instruct) from Hugging Face hub.

How others solved it

THEN Edit the model's preprocessor_config.json file to either remove the 'image_processor_type' key entirely, or replace it with 'Qwen2VLImageProcessor' to force use of the slow image processor. Alternatively, pin the transformers library to a commit before the slow processor was removed (e.g., 1931a351408dbd1d0e2c4d6d7ee0eb5e8807d7bf).

# In preprocessor_config.json, remove or change:
# "image_processor_type": "Qwen2_5_VLImageProcessor"
# to trigger fallback to slow processor.
