Qwen2-VL on multiple gpus HuggingFace

ChanYalcn: <p>I have 4 gpus that I want to run Qwen2 VL models.</p>
<pre data-code-wrap="python"><code class="lang-python">model_name="Qwen/Qwen2-VL-2B-Instruct"
model = Qwen2VLForConditionalGeneration.from_pretrained(
          model_name, torch_dtype="auto", device_map="auto"
        )
model = nn.DataParallel(model)
processor = AutoProcessor.from_pretrained(model_name)

messages = [
        {
            "role": "user",
            "content": [
                {
                    "type": "image",
                    "image": file
                },
                {

                    "text": """Describe the image"""
                }
            ]
        }
]
text = processor.apply_chat_template(
            messages, tokenize=False, add_generation_prompt=True)
image_inputs, video_inputs = process_vision_info(messages)
inputs = processor(
            text=[text],

        )
with torch.no_grad():
    generated_ids = model.module.generate(**inputs, max_new_tokens=128)

<p>but I always get:</p>

I tried running my python script using `CUDA_LAUNCH_BLOCKING=1 python script.py` but it didnt work either.

my transformers and pytorch versions are:
```bash
transformers==4.45.0.dev0
torch==2.4.1+cu124

<p>Anyone knows how to fix?</p>

ptrblck: <p>An indexing operation is failing, which is often caused by passing a wrong index to an <code>nn.Embedding</code> layer.<br>
Check the inputs as well as the embedding dimensions and make sure the values are valid.</p>
