Usage

Use in 🤗 Transformers

First, install the required dependencies:

pip install transformers accelerate qwen-vl-utils[decord]==0.0.8

Then, use the following code to load the model and generate responses:

python

from transformers import AutoModelForImageTextToText, AutoProcessor

model_name = "karakuri-ai/karakuri-vl-2-8b-thinking-2603"
model = AutoModelForImageTextToText.from_pretrained(
    model_name, torch_dtype="auto", device_map="auto"
)
processor = AutoProcessor.from_pretrained(model_name)

messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "image",
                "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
            },
            {"type": "text", "text": "Describe this image."},
        ],
    }
]

# Preparation for inference
inputs = processor.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_dict=True,
    return_tensors="pt"
)
inputs = inputs.to(model.device)

# Inference: Generation of the output
generated_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids_trimmed = [
    out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
    generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)

Training Details

Training Infrastructure

Hardware: The model was trained on Amazon EC2 trn2.48xlarge instances.
Software: We use code based on neuronx-distributed.
