🔥 News

• [8/28] 🔥 We release our video evaluation benchmark VideoVista and the automatically generated video instruction tuning data VideoVista-Train.

• [5/31] 🔥 The checkpoint of Uni-MoE-v2 with 8 experts is now available for downloading and inference. For more details, please refer to the Uni_MoE_v2_weights table.

• [4/28] 🔥 We have upgraded the Uni-MoE codebase to facilitate training across multiple Nodes and GPUs. Explore this enhanced functionality in our revamped fine-tuning script. Additionally, we have introduced a version that integrates distributed MoE modules. This enhancement allows for training our model with parallel processing at both the expert and modality levels, enhancing efficiency and scalability. For more details, please refer to the Uni_MoE_v2 documentation.

• [3/7] 🔥 We released Uni-MOE: Scaling Unified Multimodal LLMs with Mixture of Experts. We proposed the development of a unified Multimodal LLM (MLLM) utilizing the MoE framework, which can process diverse modalities, including audio, image, text, and video. Checkout the paper and demo.

🌟 Structure

The model architecture of Uni-MoE is shown below. Three training stages contain: 1) Utilize pairs from different modalities and languages to build connectors that map these elements to a unified language space, establishing a foundation for multimodal understanding; 2) Develop modality-specific experts using cross-modal data to ensure deep understanding, preparing for a cohesive multi-expert model; 3) Incorporate multiple trained experts into LLMs and refine the unified multimodal model using the LoRA technique on mixed multimodal data.

⚡️ Install

The following instructions are for Linux installation. We would like to recommend the requirements as follows.

• Python == 3.9.16
• CUDA Version >= 11.7

1. Clone this repository and navigate to the Uni-MoE folder

git clone https://github.com/HITsz-TMG/UMOE-Scaling-Unified-Multimodal-LLMs.git
cd UMOE-Scaling-Unified-Multimodal-LLMs/Uni_MoE

2. Install Package

conda create -n unimoe python==3.9.16
conda activate unimoe
pip install -r env.txt

3. Replace all the absolute pathnames '/path/to/' with your specific path to the Uni-MoE file (Including all the eval_x.py/inference_x.py/train_mem_x.py/data.py/demo.py files and config.json files from the model weights)

⚡️ Uni-MOE Weights

To use our model, all weights should be downloaded.

After downloading all of them, organize the weights as follows in 'Uni_MoE/checkpoint' folder:

└── checkpoint
    ├── Uni-MoE-audio-base
    ├── Uni-MoE-audio-e2
    ├── Uni-MoE-speech-base
    ├── Uni-MoE-speech-e2
    ├── Uni-MoE-speech-base-interval
    ├── Uni-MoE-speech-v1.5
    ├── clip-vit-large-patch14-336
    ├── whisper-small
    └── BEATs_iter3_plus_AS2M.pt

Model	Checkpoint
vision encoder	CLIP ViT-L/14 336px
speech encoder	whisper small
audio encoder	BEATs_iter3+ (AS2M)
Uni-MoE-audio-base-model	Uni-MoE/Uni-MoE-audio-base
Uni-MoE-audio-fine-tuned-chekpoint	Uni-MoE/Uni-MoE-audio-e2
Uni-MoE-speech-base-model	Uni-MoE/Uni-MoE-speech-base
Uni-MoE-speech-fine-tuned-chekpoint	Uni-MoE/Uni-MoE-speech-e2
Uni-MoE-speech-base-interval	Uni-MoE/Uni-MoE-speech-base-interval
Uni-MoE-speech-v1.5	Uni-MoE/Uni-MoE-speech-v1.5

• Uni-MoE-speech refers to the MOE-Task2 and Uni-MoE-audio refers to the MOE-Task3 in our paper.
• 'Uni-MoE-base' is the backbone containing LLMs and trained parameters gained from Training Stage 2: Training Modality-Specific Expert.

Experimental Results

🌈 How to infer and deploy your demo

1. Make sure that all the weights are downloaded and the running environment is set correctly.
2. run inference scripts inference_audio.sh and inference_speech.sh using bash inference_audio.sh bash inference_speech.sh or run the following commands to inference:

cd /path/to/Uni_MoE
conda activate unimoe
python Uni_MoE_audio/inference_all.py

cd /path/to/Uni_MoE
conda activate unimoe
python Uni_MoE_speech/inference_all.py

To launch the online demo ( It is highly recommended to launch the demo with Uni-MoE-speech-v1.5 that need the basic parameters of Uni-MoE-speech-base-interval), run:

cd /path/to/Uni_MoE
conda activate unimoe
python demo/demo.py
python demo/app.py

🌈 How to train and evaluate on datasets

Training:

1. Make sure that all the weights are downloaded and the environment is set correctly, especially for the base model.
2. Our training data can be downloaded from UMOE-Speech-453k.json and UMOE-Cap-453k.json.
3. Relevant vision and audio files: Dataset
4. Run training scripts: finetune_audio.sh or finetune_speech.sh using bash finetune_audio.sh bash finetune_speech.sh, remember to modify the training set with your own preference.
5. For multiple GPUs training, run training scripts: finetune_speech_dp.sh using bash finetune_speech_dp.sh, remember to modify the training set with your own preference.

Evaluation:

1. Prepare the evaluation set using the form as samples.json.
2. Run evaluation scripts: eval_audio.sh or eval_speech.sh using bash eval_audio.sh bash eval_speech.sh or run the following commands to eval:

cd /path/to/Uni_MoE
conda activate unimoe
python Uni_MoE_audio/eval.py\
 --data_path /path/to/clotho.json\
 --data_type clothov1\
 --output test.json

cd /path/to/Uni_MoE
conda activate unimoe
python Uni_MoE_speech/eval.py\
 --data_path /path/to/vqa_eval.json\
 --data_type vqa\
 --output test.json

We recommend using 80GB GPU RAM to run all experiments.
