🚀 mPLUG-Owl3

mPLUG-Owl3是一款先进的多模态大语言模型，旨在应对长图像序列理解的挑战。它提出了Hyper Attention技术，将多模态大语言模型中长视觉序列理解的速度提升了六倍，能够处理长度达八倍的视觉序列。同时，在单图像、多图像和视频任务上保持了出色的性能。

🚀 快速开始

加载mPLUG-Owl3

目前仅支持attn_implementation为['sdpa', 'flash_attention_2']。

import torch
model_path = 'mPLUG/mPLUG-Owl3-7B-240728'
config = mPLUGOwl3Config.from_pretrained(model_path)
print(config)
# model = mPLUGOwl3Model(config).cuda().half()
model = mPLUGOwl3Model.from_pretrained(model_path, attn_implementation='sdpa', torch_dtype=torch.half)
model.eval().cuda()

与图像进行对话

from PIL import Image

from transformers import AutoTokenizer, AutoProcessor
from decord import VideoReader, cpu    # pip install decord
model_path = 'mPLUG/mPLUG-Owl3-7B-240728'
tokenizer = AutoTokenizer.from_pretrained(model_path)
processor = model.init_processor(tokenizer)

image = Image.new('RGB', (500, 500), color='red')

messages = [
    {"role": "user", "content": """<|image|>
Describe this image."""},
    {"role": "assistant", "content": ""}
]

inputs = processor(messages, images=[image], videos=None)

inputs.to('cuda')
inputs.update({
    'tokenizer': tokenizer,
    'max_new_tokens':100,
    'decode_text':True,
})


g = model.generate(**inputs)
print(g)

与视频进行对话

from PIL import Image

from transformers import AutoTokenizer, AutoProcessor

    'decode_text':True,
