Requirements

  • pytroch >= 1.3.0
  • tensorboardX
  • cv2
  • scipy

Usage

Data preparation

UCF101 dataset

  • Download the original UCF101 dataset from the official website. And then extarct RGB images from videos.
  • Or direclty download the pre-processed RGB data of UCF101 here provided by feichtenhofer.

Pre-train

Train with pace prediction task on S3D-G, the default clip length is 64 and input video size is 224 x 224.

python train.py --rgb_prefix RGB_DIR --gpu 0,1,2,3 --bs 32 --lr 0.001 --height 256 --width 256 --crop_sz 224 --clip_len 64

Train with pace prediction task on c3d/r3d/r21d, the default clip length is 16 and input video size is 112 x 112.

python train.py --rgb_prefix RGB_DIR --gpu 0 --bs 30 --lr 0.001 --model c3d/r3d/r21d --height 128 --width 171 --crop_sz 112 --clip_len 16
