Libraries

How to use jcwang0602/VPTracker with Transformers:

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

pipe = pipeline("image-text-to-text", model="jcwang0602/VPTracker")
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)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("jcwang0602/VPTracker")
model = AutoModelForMultimodalLM.from_pretrained("jcwang0602/VPTracker", device_map="auto")
messages = [
    {
        "role": "user",

            {"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=256)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

VPTracker (Qwen3.5-2B)

This repository contains the VPTracker full-parameter fine-tune from experiment 069. It uses Qwen3.5-2B as the base model and location-aware visual prompts for global vision-language tracking.

The checkpoint was trained with seed 42 and the ms-swift 4.4.0 development environment. The current code records upstream ms-swift v4.5.3 for inference and future training; verify the loading smoke test after upgrading runtime dependencies.

Loading

from transformers import AutoProcessor, Qwen3_5ForConditionalGeneration

model_id = "jcwang0602/VPTracker"
processor = AutoProcessor.from_pretrained(model_id)
model = Qwen3_5ForConditionalGeneration.from_pretrained(model_id, device_map="auto")

The model card describes the 069 checkpoint only. Dataset preparation, visual-prompt rendering, evaluation, and reward plugins are available in the VPTracker code repository.
