Installation Note

Tested with Python 3.8.13 on Ubuntu (22.04).

  • Setup an empty pip environment
  • Install packages using pip install -r requirements.txt
  • Place dataset in ./data/ Download Link
  • Run main.py

Please note that if you're running the code from Pycharm (or another IDE) you may need to manually set the working path to PROJECT_PATH

Run python main.py to train the model.

Improvements over the original paper

  • Removed smoothness loss as it was in conflict with the alignment loss. This leads to better and more stable results.
  • Add support for gated attention [1] leading to a +3% improvement in AP frame-level.

To replicate the results of the paper, run:

python main.py --batch-size 8 --alpha 2e-8 --gamma 0.5 --no-gated-attention
