How to use TIGER-Lab/PixelReasoner-WarmStart with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="TIGER-Lab/PixelReasoner-WarmStart")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("TIGER-Lab/PixelReasoner-WarmStart")
model = AutoModelForImageTextToText.from_pretrained("TIGER-Lab/PixelReasoner-WarmStart")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Hi!

Sergio from HF here. Congrats on the release :)
I'm updating the library_name and pipeline_tag for the model to improve its visibility and reproducibility.

Using the most appropriate library_name and pipeline_tag ensures the model is automatically indexed in the Hub's Models tab and enables features like the “Use this model” button.

Resulting in something like this when we access Use this model:

Incorporating examples and filling out the Model Card also greatly improves visibility, so we recommend spending some time on it 🙂
Happy to help if you have any further questions!
