It is highly recommended to try our online demo first.
To run a video-based LLM (Large Language Model) web demonstration on your device, you will first need to ensure that you have the necessary model checkpoints prepared, followed by adhering to the steps outlined to successfully launch the demo.
- Launch a gradio app directly (VideoLLaMA2-7B is adopted by default):
python videollama2/serve/gradio_web_server_adhoc.py- Launch a global controller
cd /path/to/VideoLLaMA2
python -m videollama2.serve.controller --host 0.0.0.0 --port 10000- Launch a gradio webserver
python -m videollama2.serve.gradio_web_server --controller http://localhost:10000 --model-list-mode reload- Launch one or multiple model workers
# export HF_ENDPOINT=https://hf-mirror.com # If you are unable to access Hugging Face, try to uncomment this line.
python -m videollama2.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path /PATH/TO/MODEL1
python -m videollama2.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40001 --worker http://localhost:40001 --model-path /PATH/TO/MODEL2
python -m videollama2.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40002 --worker http://localhost:40002 --model-path /PATH/TO/MODEL3
...To facilitate further development on top of our codebase, we provide a quick-start guide on how to train a customized VideoLLaMA2 with VideoLLaVA dataset and evaluate the trained model on the mainstream video-llm benchmarks.

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 bash scripts/eval/eval_video_qa_mvbench.shIf you want to train a video-llm on your data, you need to follow the procedures below to prepare the video/image sft data:
- Suppose your data structure is like:
VideoLLaMA2
├── datasets
│ ├── custom_sft
│ | ├── images
│ | ├── videos
| | └── custom.json- Then you should re-organize the annotated video/image sft data according to the following format:
[
{
"id": 0,
"video": "images/xxx.jpg",
"conversations": [
{
"from": "human",
"value": "<image>\nWhat are the colors of the bus in the image?"
},
{
"from": "gpt",
"value": "The bus in the image is white and red."
},
...
],
}
{
"id": 1,
"video": "videos/xxx.mp4",
"conversations": [
{
"from": "human",
"value": "<video>\nWhat are the main activities that take place in the video?"
},
{
"from": "gpt",
"value": "The main activities that take place in the video are the preparation of camera equipment by a man, a group of men riding a helicopter, and a man sailing a boat through the water."
},
...
],
},
...
]- Modify the
scripts/custom/finetune.sh:
...
--data_path datasets/custom_sft/custom.json
--data_folder datasets/custom_sft/
