Llama-3-EvoVLM-JP-v2 is an experimental general-purpose Japanese VLM with interleaved text and image as inputs. This model was created using the Evolutionary Model Merge method. Please refer to our report and blog for more details. This model was produced by merging the following models. We are grateful to the developers of the source models.

Usage

Use the code below to get started with the model.

Click to expand

First, you need to install packages for inference using the Mantis. See here.

pip install git+https://github.com/TIGER-AI-Lab/Mantis.git

python

import requests
from PIL import Image

import torch
from mantis.models.conversation import Conversation, SeparatorStyle
from mantis.models.mllava import chat_mllava, LlavaForConditionalGeneration, MLlavaProcessor
from mantis.models.mllava.utils import conv_templates
from transformers import AutoTokenizer

# 1. Set the system prompt
conv_llama_3_elyza = Conversation(
    system="<|start_header_id|>system<|end_header_id|>\n\nあなたは誠実で優秀な日本人のアシスタントです。特に指示が無い場合は、常に日本語で回答してください。",
    roles=("user", "assistant"),
    messages=(),
    offset=0,
    sep_style=SeparatorStyle.LLAMA_3,
    sep="<|eot_id|>",
)
conv_templates["llama_3"] = conv_llama_3_elyza

# 2. Load model
device = "cuda" if torch.cuda.is_available() else "cpu"
model_id = "SakanaAI/Llama-3-EvoVLM-JP-v2"

processor = MLlavaProcessor.from_pretrained("TIGER-Lab/Mantis-8B-siglip-llama3")
processor.tokenizer.pad_token = processor.tokenizer.eos_token

model = LlavaForConditionalGeneration.from_pretrained(model_id, torch_dtype=torch.float16, device_map=device).eval()

# 3. Prepare a generate config
generation_kwargs = {
    "max_new_tokens": 128,
    "num_beams": 1,
    "do_sample": False,
    "no_repeat_ngram_size": 3,
}

# 4. Generate
text = "<image>の信号は何色ですか？"
url_list = [
    "https://images.unsplash.com/photo-1694831404826-3400c48c188d?q=80&w=2070&auto=format&fit=crop&ixlib=rb-4.0.3&ixid=M3wxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8fA%3D%3D",

]
images = [
   Image.open(requests.get(url_list[0], stream=True).raw).convert("RGB")
]

response, history = chat_mllava(text, images, model, processor, **generation_kwargs)

print(response)
# 信号の色は、青色です。

# 5. Multi-turn conversation
text = "では、<image>の信号は？"
images += [
   Image.open(requests.get(url_list[1], stream=True).raw).convert("RGB")
]
response, history = chat_mllava(text, images, model, processor, history=history, **generation_kwargs)

print(response)
# 赤色
