Inference Example

CUDA_VISIBLE_DEVICES=0 python chat.py \
  --version="ZechenBai/VideoLISA-3.8B" \

  --save_overlay

> Please input your prompt: In this video, there is something that shocks the cat and makes it jump. Can you find the object?
> Please input the video path: examples/RBrZsgy4-SQ.mp4

Prepare Data for Training

First, please prepare the image data following this instruction in LISA.

We introduce the video datasets used in this project. Note that the data paths for video datasets are currently hard-coded in each dataset file in the utils folder. You may need to adjust it accordingly.

ReasonVOS

Please refer to BENCHMARK.md

MeViS

Download the dataset from the official release. Then, extract and organize the file. We expect the directory structure to be the following:

mevis
├── train                       // Split Train
│   ├── JPEGImages
│   │   ├── <video #1  >
│   │   ├── <video #2  >
│   │   └── <video #...>
│   │
│   ├── mask_dict.json
│   └── meta_expressions.json
│
├── valid_u                     // Split Val^u
│   ├── JPEGImages
│   │   └── <video ...>
│   │
│   ├── mask_dict.json
│   └── meta_expressions.json
│
└── valid                       // Split Val
    ├── JPEGImages
    │   └── <video ...>
    │
    └── meta_expressions.json

Ref-YouTube-VOS and Ref-DAVIS-17

Prepare Ref-YouTube-VOS and Ref-DAVIS-17 datasets following the instructions of ReferFormer.

YouTube-VOS

Download teh dataset from the website and organize it as follows:

YTVOS
├── train
│   ├── JPEGImages
│   ├── Annotations
│   ├── meta.json

Training

We provide a sample training script in run_train.sh. In our own experiments, we use 8 node (64 A10 24G GPUs) in total to train the model. Under this setting, we set batch_size=2 and grad_accumulation_steps=1, so that the global effective batch size is batch_size*grad_accumulation_steps*num_gpus=128. You can modify these settings based on your hardwares. However, we did not explore other training hyper-parameters. If you don't have sufficient GPUs, don't give up, you may still try to train the model with small batch size. One tip: if you use small batch size, also reducing the learning rate might help.

After training finished, to get the full model weight:

cd ./runs/video-lisa-3.8b-3k-iter/ckpt_model && python zero_to_fp32.py . ../pytorch_model.bin

Weight merging

Since the script do LoRA training with the help of deepspeed by default, after training, you need to merge the lora weights back to the model.

CUDA_VISIBLE_DEVICES="" python merge_lora_weights_and_save_hf_model.py \
  --version="MBZUAI/LLaVA-Phi-3-mini-4k-instruct" \
  --weight="runs/video-lisa-3.8b-3k-iter/pytorch_model.bin" \
  --save_path="runs/video-lisa-3.8b-3k-iter/merged"
