# Model Card for LLaVA-LLaMA-3-8B

<!-- Provide a quick summary of what the model is/does. -->

A reproduced LLaVA LVLM based on Llama-3-8B LLM backbone. Not an official implementation.

## Model Details
Follows LLavA-1.5 pre-train and supervised fine-tuning data.

## How to Use

You can load the model and perform inference as follows:
```python
from llava.conversation import conv_templates, SeparatorStyle
from llava.model.builder import load_pretrained_model
from llava.mm_utils import tokenizer_image_token, process_images, get_model_name_from_path
from PIL import Image
import requests

# load model and processor
device = "cuda" if torch.cuda.is_available() else "cpu"
model_name = get_model_name_from_path(weizhiwang/LLaVA-Llama-3-8B)
tokenizer, model, image_processor, context_len = load_pretrained_model(weizhiwang/LLaVA-Llama-3-8B, None, model_name, False, False, device=device)

# prepare inputs for the model
text = '<image>' + '\n' + "Describe the image."
conv.append_message(conv.roles[0], text)
conv.append_message(conv.roles[1], None)
url = "https://huggingface.co/adept/fuyu-8b/resolve/main/bus.png"
image_tensor = image_processor.preprocess(image, return_tensors='pt')['pixel_values'].half().cuda()

# autoregressively generate text
with torch.inference_mode():
    output_ids = model.generate(
        input_ids,
        images=image_tensor,
        do_sample=False,
        max_new_tokens=512,
        use_cache=True)

outputs = tokenizer.batch_decode(output_ids[:, input_ids.shape[1]:], skip_special_tokens=True)
print(outputs[0])
```



Please refer to a forked [LLaVA-Llama-3](https://github.com/Victorwz/LLaVA-Llama-3) git repo for usage. The data loading function and fastchat conversation template are changed due to a different tokenizer.
