1. Environment setup

conda create -n cmd python=3.8 -y
conda activate cmd
pip install -r requirements.txt

2. Dataset

Dataset download

Currently, we provide experiments for UCF-101. You can place the data that you want and can specifiy it via --data-path arguments in training scripts.

UCF-101

UCF-101
|-- class1
    |-- video1.avi
    |-- video2.avi
    |-- ...
|-- class2
    |-- video1.avi
    |-- video2.avi
    |-- ...
    |-- ...

3. Training

Autoencoder

 torchrun --nnodes=[NUM_NODES] --nproc_per_node=[NUM_GPU] train_ae.py \
    --dataset-name UCF101 \ 
    --data-path /data/UCF-101 \
    --global-batch-size [BATCH_SIZE] \ 
    --results-dir [LOG_DIRECTORY] 
    --mode pixel \
    --ckpt-every 20000

Motion Diffusion Model

python train_motion_diffusion.py \ 
  --nnodes=[NUM_NODES] \ 
  --nproc_per_node=[NUM_GPUS] 
    --dataset-name UCF101 \ 
    --data-path /data/UCF-101 \
    --global-batch-size [BATCH_SIZE] \   
    --results-dir [LOG_DIRECTORY]
    --mode pixel \
    --ckpt-every 20000

Content Diffusion Model

python train_content_diffusion.py \ 
  --nnodes=[NUM_NODES] \ 
  --nproc_per_node=[NUM_GPUS] 
    --dataset-name UCF101 \ 
    --data-path /data/UCF-101 \
    --global-batch-size [BATCH_SIZE] \   
    --results-dir [LOG_DIRECTORY]
    --mode pixel \
    --ckpt-every 20000 \
    --motion-model-config [MOTION_MODEL_CONFIG]

Then these scripts will automatically create the folder in [LOG_DIRECTORY] to save logs and checkpoints.

Note

It's possible that this code may not accurately replicate the results outlined in the paper due to potential human errors during the preparation and cleaning of the code for release. If you encounter any difficulties in reproducing our findings, please don't hesitate to inform us. Additionally, we'll make an effort to carry out sanity-check experiments in the near future.
