MoE-LLaVA: Mixture of Experts for Large Vision-Language Models

If you like our project, please give us a star โญ on GitHub for latest update.

๐Ÿ“ฐ News

  • [2024.01.30] The paper is released.
  • [2024.01.27] ๐Ÿค—Hugging Face demo and all codes & datasets are available now! Welcome to watch ๐Ÿ‘€ this repository for the latest updates.

๐Ÿ˜ฎ Highlights

MoE-LLaVA shows excellent performance in multi-modal learning.

๐Ÿ”ฅ High performance, but with fewer parameters

  • with just 3B sparsely activated parameters, MoE-LLaVA demonstrates performance comparable to the LLaVA-1.5-7B on various visual understanding datasets and even surpasses the LLaVA-1.5-13B in object hallucination benchmarks.

๐Ÿš€ Simple baseline, learning multi-modal interactions with sparse pathways.

  • With the addition of a simple MoE tuning stage, we can complete the training of MoE-LLaVA on 8 V100 GPUs within 2 days.

๐Ÿค— Demo

Gradio Web UI

Highly recommend trying out our web demo by the following command, which incorporates all features currently supported by MoE-LLaVA. We also provide online demo in Huggingface Spaces.

# use phi2
deepspeed --include localhost:0 moellava/serve/gradio_web_server.py --model-path "LanguageBind/MoE-LLaVA-Phi2-2.7B-4e" 
# use qwen
deepspeed --include localhost:0 moellava/serve/gradio_web_server.py --model-path "LanguageBind/MoE-LLaVA-Qwen-1.8B-4e" 
# use stablelm
deepspeed --include localhost:0 moellava/serve/gradio_web_server.py --model-path "LanguageBind/MoE-LLaVA-StableLM-1.6B-4e"

๐Ÿค– API

We open source all codes. If you want to load the model (e.g. LanguageBind/MoE-LLaVA) on local, you can use the following code snippets.

Using the following command to run the code.

deepspeed predict.py
import torch
from moellava.constants import IMAGE_TOKEN_INDEX, DEFAULT_IMAGE_TOKEN
from moellava.conversation import conv_templates, SeparatorStyle
from moellava.model.builder import load_pretrained_model

    device = 'cuda'
    load_4bit, load_8bit = False, False  # FIXME: Deepspeed support 4bit or 8bit?
    model_name = get_model_name_from_path(model_path)
    tokenizer, model, processor, context_len = load_pretrained_model(model_path, None, model_name, load_8bit, load_4bit, device=device)
    image_processor = processor['image']
    conv_mode = "phi"  # qwen or stablelm
    conv = conv_templates[conv_mode].copy()
    roles = conv.roles
    image_tensor = image_processor.preprocess(image, return_tensors='pt')['pixel_values'].to(model.device, dtype=torch.float16)

    print(f"{roles[1]}: {inp}")
    inp = DEFAULT_IMAGE_TOKEN + '\n' + inp
    conv.append_message(conv.roles[0], inp)
    conv.append_message(conv.roles[1], None)
    prompt = conv.get_prompt()
    input_ids = tokenizer_image_token(prompt, tokenizer, IMAGE_TOKEN_INDEX, return_tensors='pt').unsqueeze(0).cuda()
    stop_str = conv.sep if conv.sep_style != SeparatorStyle.TWO else conv.sep2
    keywords = [stop_str]
    stopping_criteria = KeywordsStoppingCriteria(keywords, tokenizer, input_ids)

    with torch.inference_mode():
        output_ids = model.generate(
            input_ids,
            images=image_tensor,
            do_sample=True,
            temperature=0.2,
            max_new_tokens=1024,
            use_cache=True,
            stopping_criteria=[stopping_criteria])

    outputs = tokenizer.decode(output_ids[0, input_ids.shape[1]:], skip_special_tokens=True).strip()
    print(outputs)

if __name__ == '__main__':
    main()
