Model

LLaMA-VID simply contains three parts: encoder and decoder are adopted to produce visual embedding and text-guided features, respectively; context token and content token are transformed with the tailored token generation strategy; instruction tuning is designed to unleash the potential of LLMs for image and video.

We provide all our fully finetuned models on Stage 1 and 2 data (Long Video + Stage 3) for LLaMA-VID:

Train

LLaMA-VID training consists of three stages: (1) feature alignment stage: bridge the vision and language tokens; (2) instruction tuning stage: teach the model to follow multimodal instructions; (3) long video tuning stage: extend the position embedding and teach the model to follow hour-long video instructions.

LLaMA-VID is trained on 8 A100 GPUs with 80GB memory. To train on fewer GPUs, you can reduce the per_device_train_batch_size and increase the gradient_accumulation_steps accordingly. Always keep the global batch size the same: per_device_train_batch_size x gradient_accumulation_steps x num_gpus.

Please make sure you download and organize the data following Preparation before training.

Image Only

If you only want to train and finetune LLaMA-VID on image-based data, please run the following command for Vicuna-7B with image size 336:

bash scripts/image_only/train/stage_1_2_full_v7b_336.sh

or for Vicuna-13B with image size 336:

bash scripts/image_only/train/stage_1_2_full_v13b_336.sh

You can also try that with a smaller image size 224 and less visual tokens:

bash scripts/image_only/train/stage_1_2_full_v7b_224_grid_4.sh

Please find more training scripts in scripts/image_only/train.

Short Video

If you are interested in training and finetuning LLaMA-VID on short video-based data, please run the following command for Vicuna-7B with image size 224:

bash scripts/video/train/stage_1_2_full_v7b_224_fps_1.sh

or for Vicuna-13B with image size 224:

bash scripts/video/train/stage_1_2_full_v13b_224_fps_1.sh

Please find more training scripts in scripts/video/train.

Long Video

We provide dataset and scripts for long video-based training. Please download the long video-based data following Preparation and organize them as in Structure. In the training stage, we first extract all the frames from the long video and save the visual features local for efficient training.

python scripts/extra_tool/extract_movienet_features.py \
    --video_dir <path to movienet video> \
    --files_dir <path to movienet files> \ # files in downladed MovieNet.tar.gz
    --feat_dir <path to output features>

And run the following command for Vicuna-7B with image size 224:

bash scripts/video/train/stage_3_full_v7b_224_longvid.sh

Evaluation

We perform evaluation on both image-based and video-based benchmarks. Please download the evaluation data following Preparation and organize them as in Structure.

Image Only

LLM	Res.	Model	GQA	MMB	MME	POPE	SEED	SQA-Image	VizWiz	VQA v2
Vicuna-7B	224	ckpt	63.0	65.3	1405.6	86.6	59.7	67.7	52.5	78.3
Vicuna-7B	336	ckpt	64.3	65.1	1521.4	86.0	59.9	68.3	54.2	79.3
Vicuna-13B	336	ckpt	65.0	66.6	1542.3	86.0	62.3	70.0	54.3	80.0

If you want to evaluate the model on image-based benchmarks, please use the scripts in scripts/image_only/eval. For example, run the following command for GQA evaluation:

bash scripts/image_only/eval/gqa.sh

Please find more evaluation scripts in scripts/image_only/eval.

Vicuna-13B	224	ckpt	70.0	58.9	47.5	3.07	3.05	3.60	2.58	2.63

If you want to evaluate the model on video-based benchmarks, please use the scripts in scripts/video/eval. For example, run the following command for MSVD-QA evaluation:

bash scripts/video/eval/msvd_eval.sh

Please find more evaluation scripts in scripts/video/eval.

CLI Inference

Chat with images and videos using LLaMA-VID without the need of Gradio interface. It also supports multiple GPUs, 4-bit and 8-bit quantized inference. With 4-bit quantization. Please try this for image or video inference:

python -m llamavid.serve.cli \
    --model-path work_dirs/llama-vid/llama-vid-7b-full-336 \
    --image-file <path to your image>

or try this for video inference:

python -m llamavid.serve.cli \
    --model-path work_dirs/llama-vid/llama-vid-7b-full-224-video-fps-1 \
    --image-file <path to your video> \
    --temperature 0.5

You can also try 4bit or 8bit for efficient inference

python -m llamavid.serve.cli \
    --model-path work_dirs/llama-vid/llama-vid-7b-full-224-video-fps-1 \
    --image-file <path to your video>
    --temperature 0.5 \
    --load-4bit

Long Video Inference

For long video, if you want to inference on videos in movienet, please first process the video data and subtitles like this:

python scripts/extra_tool/extract_movienet_features.py \
    --video_dir <path to movienet video> \
    --files_dir <path to movienet files> \ # files in downladed MovieNet.tar.gz
    --feat_dir <path to output features>

If you want to inference with your customized video, please first process the video data and subtitles like this:

python scripts/extra_tool/extract_video_features_subtitles.py \
    --video_file <path to customized video> \
    --feat_dir <path to output features>

Then, please try this for long video inference:

python llamavid/serve/run_llamavid_movie.py \
    --model-path work_dirs/llama-vid/llama-vid-7b-full-224-long-video \
    --video-file <path to your processed video file> \
    --load-4bit

Gradio Web UI

Here, we adopt the Gradio UI similar to that in LLaVA to provide a user-friendly interface for LLaMA-VID. To launch a Gradio demo locally, please run the following commands one by one. If you plan to launch multiple model workers to compare between different checkpoints, you only need to launch the controller and the web server ONCE.

Launch a controller

python -m llamavid.serve.controller --host 0.0.0.0 --port 10000

Launch a gradio web server.

python -m llamavid.serve.gradio_web_server --controller http://localhost:10000 --model-list-mode reload

You just launched the Gradio web interface. Now, you can open the web interface with the URL printed on the screen. You may notice that there is no model in the model list. Do not worry, as we have not launched any model worker yet. It will be automatically updated when you launch a model worker.

Launch a model worker

This is the actual worker that performs the inference on the GPU. Each worker is responsible for a single model specified in --model-path.

python -m llamavid.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path work_dirs/llama-vid/llama-vid-vicuna-7b-short

Wait until the process finishes loading the model and you see "Uvicorn running on ...". Now, refresh your Gradio web UI, and you will see the model you just launched in the model list.

You can launch as many workers as you want, and compare between different models in the same Gradio interface. For example, short video model here. Please keep the --controller the same, and modify the --port and --worker to a different port number for each worker.

python -m llamavid.serve.model_worker_short --host 0.0.0.0 --controller http://localhost:10000 --port <different from 40000, say 40001> --worker http://localhost:<change accordingly, i.e. 40001> --model-path work_dirs/llama-vid/llama-vid-7b-full-224-video-fps-1

If you are using an Apple device with an M1 or M2 chip, you can specify the mps device by using the --device flag: --device mps.

Launch a model worker (Multiple GPUs, when GPU VRAM <= 24GB)

If the VRAM of your GPU is less than 24GB (e.g., RTX 3090, RTX 4090, etc.), you may try running it with multiple GPUs. Our latest code base will automatically try to use multiple GPUs if you have more than one GPU. You can specify which GPUs to use with CUDA_VISIBLE_DEVICES. Below is an example of running with the first two GPUs.

CUDA_VISIBLE_DEVICES=0,1 python -m llamavid.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path work_dirs/llama-vid/llama-vid-7b-full-224-long-video

Launch a model worker (4-bit, 8-bit inference, quantized)

You can launch the model worker with quantized bits (4-bit, 8-bit), which allows you to run the inference with reduced GPU memory footprint. Note that inference with quantized bits may not be as accurate as the full-precision model. Simply append --load-4bit or --load-8bit to the model worker command that you are executing. Below is an example of running with 4-bit quantization.

python -m llamavid.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path work_dirs/llama-vid/llama-vid-7b-full-224-long-video --load-4bit
