LLaVA Model Card

SGLang

This contains the necessary files to run LLaVA-1.6 34B on SGLang. You can run the server with the following command:

python -m sglang.launch_server --model-path dillonlaird/hf-llava-v1.6-34b --port 30000

There seems to be issues with the chat formatting when using the sglang interface so I recommend querying the server directly and formatting the string yourself:

import requests
from transformers import AutoTokenizer


def generate(image_path: str, prompt: str, tokenizer):
    chat = [
        {"role": "system", "content": "Answer the question."},
        {"role": "user", "content": "<image>\n" + prompt},
    ]
    chat_str = tokenizer.apply_chat_template(chat, tokenize=False)
    chat_str += "<|img_start|>assistant\n"
    sampling_params = {"temperature": 0.2, "max_new_tokens": 1536}
    res = requests.post(
        "http://localhost:30000/generate",
        json={
            "text": chat_str,
            "image_data": image_path,
            "sampling_params": sampling_params,
        },
    )
    return res.json()["text"]


if __name__ == "__main__":
    tokenizer = AutoTokenizer.from_pretrained("liuhaotian/llava-v1.6-34b")
    image_path = "path/to/image.jpg"
    prompt = "What is the name of the mountain?"
    desc = generate(image_path, prompt, tokenizer)

Model details

Model type: LLaVA is an open-source chatbot trained by fine-tuning LLM on multimodal instruction-following data. It is an auto-regressive language model, based on the transformer architecture. Base LLM: NousResearch/Nous-Hermes-2-Yi-34B

Model date: LLaVA-v1.6-34B was trained in December 2023.
