Datasets

ProLongVid data (Annotations and videos) have been uploaded to huggingface.

Models

Model	Frame (Train)	Frame (Test)	Video-MME (w/o sub)	Huggingface
Image-SFT-7B	-	32	57.6	prolongvid_image_sft_7B
ProLongVid-Stage-1-7B	32	32	60.1	prolongvid_stage1_7B
ProLongVid-Stage-2-7B	128	128	63.6	prolongvid_stage2_7B
ProLongVid-Stage-3-7B	192	192	63.8	prolongvid_7B
	192	256	64.7

Installation

For training:

- conda create -n llava python==3.10 -y
- conda activate llava
- conda install pytorch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 pytorch-cuda=12.1 -c pytorch -c nvidia -y
- pip install -e ".[train]"
- pip install bitsandbytes
- pip install tensorboardX
- pip install transformers==4.43.4
- pip install flash-attn==2.6.3 --no-build-isolation

Training

For example, for stage-2 training, run the following script:

bash scripts/train/train_stage2.sh 

Eval

Please use the code of lmms-eval in this repo to install the environment, and follow the instruction of this version to perform evaluation of video benchmarks.

ToDo

• More comprehensive training and testing tutorials.
• More efficient training framework that supports sequence parallelism.
• Original Dense Video Caption data.
• New models trained from stronger image-LMM baseline.
