RoadFighter

Installation

  • The code was tested on Ubuntu 16.04 with Python 3.6
  • Install packages by typing the command: pip install -r requirements.txt.
  • For Road Fighter, clone and install the repo: https://github.com/ShaniGam/retro

Getting Started

Breakout Examples

  • Train Breakout from scratch:
python -m breakout_a3c.main --num-processes 32 --variation 'standart'
  • Transfer from standart to diagonals variation and fine-tune the model:
python -m breakout_a3c.main --num-processes 32 --variation diagonals --ft-setting full-ft --test
  • Collect images for UNIT training:
python -m breakout_a3c.main --collect-images --num-collected-imgs 100000 --variation diagonals --num-processes 1
  • Train UNIT:
python -m unit.train --trainer UNIT --config unit/configs/breakout-diagonals.yaml
  • Run Breakout with UNIT:
python -m breakout_a3c.main --variation diagonals --test --ft-setting full-ft --test-gan --gan-dir breakout-diagonals --num-processes 0

Road Fighter Examples

  • Train level 1 of Road Fighter
python -m roadfighter_a2c.main --num-processes 84
  • Collect images for UNIT training:
python -m roadfighter_a2c.main -level 1 --collect-images --num-collected-imgs 100000 --num-processes 1
python -m roadfighter_a2c.main -level 2 --collect-images --num-collected-imgs 100000 --num-processes 1
  • Train UNIT:
python -m unit.train --trainer UNIT --config unit/configs/roadfighter-lvl2.yaml
  • Run Road Fighter with UNIT:
python -m roadfighter_a2c.main --load --level 2 --test-gan --gan-dir roadfighter-lvl2-kl01 --num-processes 1
  • Run Road Fighter with UNIT and Imitation Learning:
python -m roadfighter_a2c.main_imitation --load --gan-dir roadfighter-lvl2-kl01 --gan-imitation-file '00320000' --log-name lvl2.log --super-during-rl --level 2 --det-score 5350

Acknowledgments

The code was written by Shani Gamrian and is based on the repositories: pytorch-a3c, pytorch-a2c, UNIT

TO-DO

  • Add links for pretrained models.
  • Create videos.
