## Model Details

This model is an int4 model with group_size 128 and symmetric quantization of [Qwen/Qwen2-VL-72B-Instruct](https://huggingface.co/Qwen/Qwen2-VL-72B-Instruct) generated by [intel/auto-round](https://github.com/intel/auto-round). Load the model with revision="e67cae7" to use AutoGPTQ format.

## How To Use


### Requirements
The code of Qwen2-VL has been in the latest Hugging face transformers and we advise you to build from source with command `pip install git+https://github.com/huggingface/transformers`, or you might encounter the following error:
```
KeyError: 'qwen2_vl'
```

### INT4 Inference
```python
from auto_round import AutoRoundConfig ## must import for auto-round format
import requests
from PIL import Image
from transformers import Qwen2VLForConditionalGeneration, AutoTokenizer, AutoProcessor
quantized_model_path="OPEA/Qwen2-VL-72B-Instruct-int4-sym-inc"
model = Qwen2VLForConditionalGeneration.from_pretrained(
    quantized_model_path,
    torch_dtype="auto",
    device_map="auto",
    ##revision="e67cae7" ##AutoGPTQ format
)
processor = AutoProcessor.from_pretrained(quantized_model_path)
image_url = "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg"

        "role": "user",
        "content": [
            {
                "type": "image",
                "image": image_url,
            },
            {"type": "text", "text": "Describe this image."},
        ],
    }
]

# Preparation for inference
text = processor.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)
image_inputs = Image.open(requests.get(image_url, stream=True).raw)
inputs = processor(
    text=[text],
    images=image_inputs,
    padding=True,
    return_tensors="pt",
)
inputs = inputs.to(model.device)

generated_ids = model.generate(**inputs, max_new_tokens=128, do_sample=False)
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[0])

##INT4:
## The image depicts a serene beach scene at sunset. A woman is sitting on the sand, facing a large dog, likely a Labrador Retriever. The woman is wearing a plaid shirt and shorts, and she appears to be smiling as she interacts with the dog. The dog is wearing a harness and is giving the woman a paw. The sun is setting in the background, casting a warm glow over the entire scene, creating a peaceful and heartwarming atmosphere. The waves of the ocean can be seen gently rolling onto the shore behind them.

##BF16:
## The image depicts a serene beach scene at sunset. A person is sitting on the sand, facing the ocean, with their back to the camera. They are wearing a plaid shirt and shorts. Next to them, a large dog, possibly a Labrador Retriever, is sitting upright, facing the person. The dog is wearing a harness. The sun is setting in the background, casting a warm glow over the entire scene, creating a peaceful and tranquil atmosphere. The waves gently lap at the shore, adding to the calm ambiance.

## Evaluation the model
pip3 install git+https://github.com/open-compass/VLMEvalKit.git@7de2dcb. The evaluation process may encounter errors that require changing model backend or evaluation code. Detailed instructions will be provided in a future update.
```bash
auto-round-mllm --eval --model OPEA/Qwen2-VL-7B-Instruct-int4-sym-inc --tasks MMBench_DEV_EN_V11,ScienceQA_VAL,TextVQA_VAL,POPE --output_dir "./eval_result"

### Generate the model
Here is the sample command to reproduce the model.
```bash
pip install auto-round
auto-round-mllm
--model Qwen/Qwen2-VL-72B-Instruct \
--device 0,1 \
--group_size 128 \
--bits 4 \
--iters 1000 \
--nsample 512 \
--seqlen 2048 \
--format 'auto_gptq,auto_round' \
--output_dir "./tmp_autoround"
```

## Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

## Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
