The Charades-Ego and Charades datasets are available at http://allenai.org/plato/charades/

All outputs are stored in the cache-dir. This includes epoch*.txt which is the classification output. All output files can be scored with the official MATLAB evaluation script provided with the Charades / CharadesEgo datasets.

Requirements:

• Python 2.7
• PyTorch

1. Download the CharadesEgo Annotations (allenai.org/plato/charades/)
2. Download the CharadesEgo RGB frames (allenai.org/plato/charades/)
3. Duplicate and edit one of the experiment files under exp/ with appropriate parameters. For additional parameters, see opts.py
4. Run an experiment by calling python exp/rgbnet.py where rgbnet.py is your experiment file
5. The checkpoints/logfiles/outputs are stored in your specified cache directory.
6. Build of the code, cite our papers, and say hi to us at CVPR.

Good luck!
