mPLUG-Owl3

Introduction

mPLUG-Owl3 is a state-of-the-art multi-modal large language model designed to tackle the challenges of long image sequence understanding. We propose Hyper Attention, which boosts the speed of long visual sequence understanding in multimodal large language models by sixfold, allowing for processing of visual sequences that are eight times longer. Meanwhile, we maintain excellent performance on single-image, multi-image, and video tasks.

What's new

mPLUG-Owl3-7B-241101 is a improved version of mPLUG-Owl3-7B-240728.

Fused Hyper Attention

mPLUG-Owl3 requires separate calculations for cross-attention and self-attention, and fuses the outputs of both through a adaptive gate. Now, we use a unified operation that only requires computing attention once.

New template for media inputs

We now use the following format to represent the splited high-resolution images. In addition, we can now enable image splitting when the input consists of multiple images to achieve further performance benefits, which the old version of mPLUG-Owl3 was not trained to handle with this combination.

<|start_cut|>2*3
<|image|> <|image|> <|image|>
<|image|> <|image|> <|image|>
<|image|><|end_cut|>

And we use the following format to represent video.

<|start_video_frame|><|image|><|image|><|image|><|end_video_frame|>

Adjusted media_offset

Previously, media_offset recorded the range of images each token could see. During training, since the images from multiple samples are concatenated together along the batch dimension, media_offset needed to be carefully modified, otherwise it would point to the wrong image. To prevent this, media_offset is now a List[List[int]], representing the position of each image in a sample within the batch in the original sequence. This design also makes the computation of the cross-attention mask and MI-Rope more efficient and convenient.

All of these changes are well handled by the processor, and you don't need to change the original way of calling it.

Quickstart

Load the mPLUG-Owl3. We now only support attn_implementation in ['sdpa', 'flash_attention_2'].

Python

import torch
from modelscope import AutoConfig, AutoModel
model_path = 'iic/mPLUG-Owl3-2B-241101'
config = AutoConfig.from_pretrained(model_path, trust_remote_code=True)
print(config)
model = AutoModel.from_pretrained(model_path, attn_implementation='flash_attention_2', torch_dtype=torch.bfloat16, trust_remote_code=True)
_ = model.eval().cuda()
device = "cuda"

Chat with images.

Python

from PIL import Image

from modelscope import AutoTokenizer
from decord import VideoReader, cpu 
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)

Chat with a video.

Python

from PIL import Image

from modelscope import AutoTokenizer
from decord import VideoReader, cpu    # pip install decord
tokenizer = AutoTokenizer.from_pretrained(model_path)
processor = model.init_processor(tokenizer)


messages = [

    def uniform_sample(l, n):
        gap = len(l) / n
        idxs = [int(i * gap + gap / 2) for i in range(n)]
        return [l[i] for i in idxs]

    vr = VideoReader(video_path, ctx=cpu(0))
    sample_fps = round(vr.get_avg_fps() / 1)  # FPS
    frame_idx = [i for i in range(0, len(vr), sample_fps)]
    if len(frame_idx) > MAX_NUM_FRAMES:
        frame_idx = uniform_sample(frame_idx, MAX_NUM_FRAMES)
    frames = vr.get_batch(frame_idx).asnumpy()
    frames = [Image.fromarray(v.astype('uint8')) for v in frames]
    print('num frames:', len(frames))
    return frames
video_frames = [encode_video(_) for _ in videos]
inputs = processor(messages, images=None, videos=video_frames)

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


g = model.generate(**inputs)

Save memory by Liger-Kernel

mPLUG-Owl3 is based on Qwen2, which can be optimized through the Liger-Kernel to reduce memory usage.

pip install liger-kernel

    model = None,
) -> None:

Save memory by setting device_map

When you have more than one GPUs, you can set the device_map='auto' to split the mPLUG-Owl3 into multiple GPUs. However, it will slowdown the inference speed.

python

model = AutoModel.from_pretrained(model_path, attn_implementation='flash_attention_2', device_map="auto", torch_dtype=torch.bfloat16, trust_remote_code=True)
_ = model.eval()
first_layer_name = list(model.hf_device_map.keys())[0]
device = model.hf_device_map[first_layer_name]
