Introduction

MixSense is a series of models based on the widely adopted vision encoder-projector-LLM architecture. In this resource, we release Llama-3-MixSense checkpoint,which is Built with Meta Llama 3 as the text encoder,and SigLIP 400M as the vision encoder . We have developed an innovative data processing method that complements the training process, reducing training costs while improving training effectiveness.,The models are trained on our restructured dataset. Details of the data organization and related research papers will be available soon.

QuickStart

Requirements

conda create -n mixsense python==3.10 -y
conda activate mixsense
pip install torch transformers==4.37.2 accelerate pillow

Usage

Llama-3-Mixsense/demo.py

python

import torch
import transformers
from transformers import AutoModelForCausalLM, AutoTokenizer
from PIL import Image
import warnings
import os


# disable some warnings
transformers.logging.set_verbosity_error()
transformers.logging.disable_progress_bar()
warnings.filterwarnings("ignore")

# set device
device = "cuda"  # or cpu

# create model
model = AutoModelForCausalLM.from_pretrained(
    "Zero-Vision/Llama-3-MixSense",
    torch_dtype=torch.float16,  # float32 for cpu
    device_map="auto",
    trust_remote_code=True,
)
tokenizer = AutoTokenizer.from_pretrained(
    "Zero-Vision/Llama-3-MixSense",
    trust_remote_code=True,
)

qs = "describe the image detailly."
input_ids = model.text_process(qs, tokenizer).to(device)

image = Image.open("example.jpg")
image_tensor = model.image_process([image]).to(dtype=model.dtype, device=device)

# generate
with torch.inference_mode():
    output_ids = model.generate(
        input_ids,
        images=image_tensor,
        max_new_tokens=2048,
        use_cache=True,
        eos_token_id=[
            tokenizer.eos_token_id,
            tokenizer.convert_tokens_to_ids(["<|eot_id|>"])[0],
        ],
    )

print(tokenizer.batch_decode(output_ids, skip_special_tokens=True)[0].strip())

Eval

We offer Llama-3-Mixsense/llama3mixsense.py for VLMEvalKit.
