Error: "No chat template is set for this processor"

I'm trying to run the example in inference/notebooks/01_single_image_understanding.ipynb, but I get this error:

 text = processor.apply_chat_template(messages, add_generation_prompt=True)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/ubuntu/transformers/src/transformers/processing_utils.py", line 1096, in apply_chat_template
    raise ValueError(
ValueError: No chat template is set for this processor. Please either set the `chat_template` attribute, or provide a chat template as an argument. See https://huggingface.co/docs/transformers/main/en/chat_templating for more information.

However, using:

tokenizer = AutoTokenizer.from_pretrained(model_id_or_path)

  processor = AriaProcessor.from_pretrained(
          model_id_or_path, tokenizer_path=model_id_or_path, chat_template=tokenizer.chat_template,
      )

Fixes it. I can open a PR if that helps!

@aymeric-roucher Thanks for pointing out this, could you kindly share some more detailed environments to reproduce this error? We just test it with transformers 4.45.0 and it seems errorless in our environment.
