Spotlights

  • A new training paradigm with a modularized design for large multi-modal language models.
  • Learns visual knowledge while support multi-turn conversation consisting of different modalities (images/videos/texts).
  • Observed abilities such as multi-image correlation and scene text understanding, vision-based document comprehension.
  • Release a visually-related instruction evaluation set OwlEval.
  • Our outstanding works on modularization:
  • Comming soon
    • Multi-lingustic support.
    • Instruction tuning on interleaved data (multiple images and videos).
    • Publish on Huggingface Hub / Model Hub
    • Huggingface space demo.
    • Instruction tuning code and pre-training code.
    • A visually-related evaluation set OwlEval to comprehensively evaluate various models.

Compatibility with v0 branch

The code in the current main branch has been refactored in Huggingface style, and several issues with the model have been fixed. We have re-trained the models and released new checnpoints in Huggingface Hub. As a result, the old code and new checkpoints are incompatible. We have moved that code into the v0 branch.

Usage

Install Requirements

  1. Create conda environment
conda create -n mplug_owl python=3.10
conda activate mplug_owl
  1. Install PyTorch
conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.7 -c pytorch -c nvidia
  1. Install other dependencies
pip install -r requirements.txt

Local Demo

We provide a script to deploy a simple demo in your local machine.

python -m serve.web_server --base-model 'your checkpoint directory' --bf16

For example, if you want to load the checkpoint MAGAer13/mplug-owl-llama-7b from Huggingface Model Hub, here is it.

python -m serve.web_server --base-model MAGAer13/mplug-owl-llama-7b --bf16

Run Model with Huggingface Style

Model initialization

If you want to load the model (e.g. MAGAer13/mplug-owl-llama-7b) from the model hub on Huggingface or on local, you can use the following code snippet.

# Load via Huggingface Style
from transformers import AutoTokenizer
from mplug_owl.modeling_mplug_owl import MplugOwlForConditionalGeneration
from mplug_owl.processing_mplug_owl import MplugOwlImageProcessor, MplugOwlProcessor

pretrained_ckpt = 'MAGAer13/mplug-owl-llama-7b'
model = MplugOwlForConditionalGeneration.from_pretrained(
    pretrained_ckpt,
    torch_dtype=torch.bfloat16,
)
image_processor = MplugOwlImageProcessor.from_pretrained(pretrained_ckpt)
tokenizer = AutoTokenizer.from_pretrained(pretrained_ckpt)
processor = MplugOwlProcessor(image_processor, tokenizer)

Model inference

Prepare model inputs.

# We use a human/AI template to organize the context as a multi-turn conversation.
# <image> denotes an image placehold.
prompts = [
'''The following is a conversation between a curious human and AI assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
Human: <image>
Human: Explain why this meme is funny.
AI: ''']

# The image paths should be placed in the image_list and kept in the same order as in the prompts.
# We support urls, local file paths and base64 string. You can custom the pre-process of images by modifying the mplug_owl.modeling_mplug_owl.ImageProcessor
image_list = ['https://xxx.com/image.jpg']

Get response.

# generate kwargs (the same in transformers) can be passed in the do_generate()
generate_kwargs = {
    'do_sample': True,
    'top_k': 5,
    'max_length': 512
}
from PIL import Image
images = [Image.open(_) for _ in image_list]
inputs = processor(text=prompts, images=images, return_tensors='pt')
inputs = {k: v.bfloat16() if v.dtype == torch.float else v for k, v in inputs.items()}
inputs = {k: v.to(model.device) for k, v in inputs.items()}
with torch.no_grad():
    res = model.generate(**inputs, **generate_kwargs)
sentence = tokenizer.decode(res.tolist()[0], skip_special_tokens=True)
print(sentence)

Run Model with provided interface

Model initialization

Build model, toknizer and processor.

from pipeline.interface import get_model
model, tokenizer, processor = get_model(pretrained_ckpt='your checkpoint directory', use_bf16='use bf16 or not')

Model inference

Prepare model inputs.

# We use a human/AI template to organize the context as a multi-turn conversation.
# <image> denotes an image placehold.
prompts = [
'''The following is a conversation between a curious human and AI assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
Human: <image>
Human: Explain why this meme is funny.
AI: ''']

# The image paths should be placed in the image_list and kept in the same order as in the prompts.
# We support urls, local file paths and base64 string. You can custom the pre-process of images by modifying the mplug_owl.modeling_mplug_owl.ImageProcessor
image_list = ['https://xxx.com/image.jpg',]

For multiple images inputs, as it is an emergent ability of the models, we do not know which format is the best. Below is an example format we have tried in our experiments. Exploring formats that can help models better understand multiple images could be beneficial and worth further investigation.

prompts = [
'''The following is a conversation between a curious human and AI assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
Human: <image>
Human: <image>
Human: Do the shirts worn by the individuals in the first and second pictures vary in color? If so, what is the specific color of each shirt?
AI: ''']

image_list = ['https://xxx.com/image_1.jpg', 'https://xxx.com/image_2.jpg']

Get response.

# generate kwargs (the same in transformers) can be passed in the do_generate()
from pipeline.interface import do_generate
sentence = do_generate(prompts, image_list, model, tokenizer, processor, 
                       use_bf16=True, max_length=512, top_k=5, do_sample=True)

Instruction Tuning

The training samples are stored in xxx.jsonl and orgnized in the following format:

{"text": "The following is a conversation between a curious human and AI assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.\nHuman: Construct a sentence using the given verb in the past tense\nshudder\nAI: She shuddered at the thought of being alone in the dark.", "task_type": "gpt4instruct_sft"}
{"image": ["xxx.jpg"], "text": "The following is a conversation between a curious human and AI assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.\nHuman: <image>\nHuman: Where is the man located in the image?\nAI: The man is located in a small restaurant, sitting and enjoying his meal.\nHuman: What type of food is the man eating in the image?\nAI: The man is eating a burrito in the image.\nHuman: What can be seen next to the man in the restaurant?\nAI: Next to the man in the restaurant, there is a fridge filled with cans of soda.\nHuman: How does the man feel as he is about to eat his meal?\nAI: The man looks happy and is smiling as he is about to take a bite of his meal.\nHuman: What unique aspect of the photo makes the scene appear distorted or unusual?\nAI: The unique aspect of this photo is that it was taken using a fish-eye lens, which creates a distorted, wide-angle view of the scene, making it appear different from a standard perspective.", "task_type": "llava_sft"}

The task_type can be in one of {'quora_chat_sft', 'sharegpt_chat_sft', 'llava_sft', 'gpt4instruct_sft'}.

Prepare your own train.jsonl and dev.jsonl and modify data_files in configs/v0.yaml.

Execute the training script.

PYTHONPATH=./ bash train_it.sh # If you want to finetune LLM, replace it with train_it_wo_lora.sh

Usage with Replicate

You can also now run the model and demo locally with cog, an open source ML tool maintained by Replicate. To get started, follow the instructions in this cog fork of mPLUG-Owl.
