Caption: The video shows a person's hands working on a white surface. They are folding a piece of fabric with a checkered pattern in shades of blue and white. The fabric is being folded into a smaller, more compact shape. The person's fingernails are painted red, and they are wearing a black and red garment. There are also a ruler and a pencil on the surface, suggesting that measurements and precision are involved in the process. ### In context learning <img src="demo_images/demo_img_1.png" height="239"> <img src="demo_images/demo_img_2.png" height="250"> ### Multi-image reasoning <img src="demo_images/demo_img_3.png" height="193"> ### VILA on Jetson Orin https://github.com/Efficient-Large-Model/VILA/assets/7783214/6079374c-0787-4bc4-b9c6-e1524b4c9dc4 ### VILA on RTX 4090 https://github.com/Efficient-Large-Model/VILA/assets/7783214/80c47742-e873-4080-ad7d-d17c4700539f ## Installation 1. Install [Anaconda Distribution](https://www.anaconda.com/download). 2. Install the necessary Python packages in the environment. ```bash ./environment_setup.sh vila ``` 3. (Optional) If you are an NVIDIA employee with a wandb account, install onelogger and enable it by setting `training_args.use_one_logger` to `True` in `llava/train/args.py`. ```bash pip install --index-url=https://sc-hw-artf.nvidia.com/artifactory/api/pypi/hwinf-mlwfo-pypi/simple --upgrade one-logger-utils ``` 4. Activate a conda environment. ```bash conda activate vila ``` ## Training VILA training contains three steps, for specific hyperparameters, please check out the [scripts/v1_5](scripts/v1_5) folder: ### Step-1: Alignment We utilize LLaVA-CC3M-Pretrain-595K dataset to align the textual and visual modalities. The stage 1 script takes in two parameters and it can run on a single 8xA100 node. ```bash bash scripts/NVILA-Lite/align.sh Efficient-Large-Model/Qwen2-VL-7B-Instruct <alias to data> ``` and the trained models will be saved to `runs/train/nvila-8b-align`. ### Step-1.5: ```bash bash scripts/NVILA-Lite/stage15.sh runs/train/nvila-8b-align/model <alias to data> ``` and the trained models will be saved to `runs/train/nvila-8b-align-1.5`. ### Step-2: Pretraining We use MMC4 and Coyo dataset to train VLM with interleaved image-text pairs. ```bash bash scripts/NVILA-Lite/pretrain.sh runs/train/nvila-8b-align-1.5 <alias to data> ``` and the trained models will be saved to `runs/train/nvila-8b-pretraining`. ### Step-3: Supervised fine-tuning This is the last stage of VILA training, in which we tune the model to follow multimodal instructions on a subset of M3IT, FLAN and ShareGPT4V. This stage runs on a 8xA100 node. ```bash bash scripts/NVILA-Lite/sft.sh runs/train/nvila-8b-pretraining <alias to data> ``` and the trained models will be saved to `runs/train/nvila-8b-SFT`. ## Evaluations We have introduce `vila-eval` command to simplify the evaluation. Once the data is prepared, the evaluation can be launched via ```bash MODEL_NAME=NVILA-15B MODEL_ID=Efficient-Large-Model/$MODEL_NAME huggingface-cli download $MODEL_ID vila-eval \ --model-name $MODEL_NAME \ --model-path $MODEL_ID \ --conv-mode auto \ --tags-include local ``` it will launch all evaluations and return a summarized result. ## Inference We provide `vila-infer` for quick inference with user prompts and images. ```bash # image description vila-infer \ --model-path Efficient-Large-Model/NVILA-15B \ --conv-mode auto \ --text "Please describe the image" \ --media demo_images/demo_img.png # video description vila-infer \ --model-path Efficient-Large-Model/NVILA-15B \ --conv-mode auto \ --text "Please describe the video" \ --media https://huggingface.co/datasets/Efficient-Large-Model/VILA-inference-demos/resolve/main/OAI-sora-tokyo-walk.mp4 ``` `vila-infer` is also compatible with VILA-1.5 models. For example: ```bash vila-infer \ --model-path Efficient-Large-Model/VILA1.5-3b \ --conv-mode vicuna_v1 \ --text "Please describe the image" \ --media demo_images/demo_img.png vila-infer \ --model-path Efficient-Large-Model/VILA1.5-3b \ --conv-mode vicuna_v1 \ --text "Please describe the video" \ --media https://huggingface.co/datasets/Efficient-Large-Model/VILA-inference-demos/resolve/main/OAI-sora-tokyo-walk.mp4 vila-infer \ --model-path Efficient-Large-Model/NVILA-15B \ --conv-mode auto \ --text "Please describe the video" \ --media https://huggingface.co/datasets/Efficient-Large-Model/VILA-inference-demos/resolve/main/OAI-sora-tokyo-walk.mp4 ``` ## Quantization and Deployment Our VILA models are quantized by [AWQ](https://arxiv.org/abs/2306.00978) into 4 bits for efficient inference on the edge. We provide a push-the-button [script](https://github.com/mit-han-lab/llm-awq/blob/main/scripts/vila_example.sh) to quantize VILA with AWQ. ### Running VILA on desktop GPUs and edge GPUs We support AWQ-quantized 4bit VILA on GPU platforms via [TinyChat](https://github.com/mit-han-lab/llm-awq/tree/main/tinychat). We provide a [tutorial](https://github.com/mit-han-lab/llm-awq/tree/main/tinychat#support-vlm-models-vila--llava) to run the model with TinyChat after quantization. We also provide an [instruction](https://github.com/mit-han-lab/llm-awq/tree/main/tinychat/serve) to launch a Gradio server (powered by TinyChat and AWQ) to serve 4-bit quantized VILA models. ### Running VILA on laptops We further support our AWQ-quantized 4bit VILA models on various CPU platforms with both x86 and ARM architectures with our [TinyChatEngine](https://github.com/mit-han-lab/TinyChatEngine). We also provide a detailed [tutorial](https://github.com/mit-han-lab/TinyChatEngine/tree/main?tab=readme-ov-file#deploy-vision-language-model-vlm-chatbot-with-tinychatengine) to help the users deploy VILA on different CPUs. ### Running VILA API server A simple API server has been provided to serve VILA models. The server is built on top of [FastAPI](https://fastapi.tiangolo.com/) and [Huggingface Transformers](https://huggingface.co/transformers/). The server can be run with the following command: #### With CLI ```bash python -W ignore server.py \ --port 8000 \ --model-path Efficient-Large-Model/NVILA-15B \ --conv-mode auto ``` #### With Docker ```bash docker build -t vila-server:latest . docker run --gpus all --ipc=host --ulimit memlock=-1 --ulimit stack=67108864 \ -v ./hub:/root/.cache/huggingface/hub \ -it --rm -p 8000:8000 \ -e VILA_MODEL_PATH=Efficient-Large-Model/NVILA-15B \ -e VILA_CONV_MODE=auto \ vila-server:latest ``` Then you can call the endpoint with the OpenAI SDK as follows: ```python from openai import OpenAI client = OpenAI( base_url="http://localhost:8000", api_key="fake-key", ) response = client.chat.completions.create( messages=[ { "role": "user", "content": [ {"type": "text", "text": "What’s in this image?"}, { "type": "image_url", "image_url": { "url": "https://blog.logomyway.com/wp-content/uploads/2022/01/NVIDIA-logo.jpg", # Or you can pass in a base64 encoded image # "url": "data:image/png;base64,<base64_encoded_image>", }, }, ], } ], model="NVILA-15B", ) print(response.choices[0].message.content) ``` ^{NOTE: This API server is intended for evaluation purposes only and has not been optimized for production use. SGLang support is coming on the way.} ## Checkpoints We release the following models: - NVILA-8B / NVILA-8B-Lite - NVILA-15B / NVILA-15B-Lite ## 🔒 License - The code is released under the Apache 2.0 license as found in the [LICENSE](./LICENSE) file. - The pretrained weights are released under the [CC-BY-NC-SA-4.0 license](https://creativecommons.org/licenses/by-nc-sa/4.0/deed.en). - The service is a research preview intended for non-commercial use only, and is subject to the following licenses and terms: - [Model License](https://github.com/facebookresearch/llama/blob/main/MODEL_CARD.md) of LLaMA.
