Some requirements only work with python 3.7

conda create -n adlr python==3.7
conda activate adlr

Install pip libraries from requirements file:

pip install -r requirements.txt

conda install pytorch torchvision torchaudio -c pytorch

# At the same level as the project repository do:
git clone https://github.com/koulanurag/ma-gym.git
cd ma-gym
pip install -e .

Python scripts in the src/scripts folder to reproduce training and evaluation. Settings for these scripts can be adjusted inside the scripts.

• src/scripts/train_selfplay
  • Training run for regular self-play
• src/scripts/train_selfplay_adversarial_policy
  • Train an adversarial policy that trains against a specified fixed victim
• src/scripts/evaluate_model
  • Evaluate trained agents by playing Pong
• src/scripts/evaluate_observation_attack
  • Evaluate agent trained with regular self-play against FGSM
• src/scripts/render_match
  • Show a Pong match with the specified trained agents

• main
  • Main script for running NFSP agents
• src/scripts/train
  • Training run for NFSP
• src/scripts/test
  • Evaluate trained NFSP agents

Run python main.py --env 'PongDuel-v0' with built-in arguments to reproduce our training and testing results. Use --obs_opp both and --obs_img both to choose between feature-based and image-based observation for the agent, respectively. Use --evaluate to test trained agents. Use --render to visualize agents playing Pong. For more details please run python main.py -h. We give some examples about how to run the script that you may want to try out.

• python main.py --env 'PongDuel-v0' --obs_opp both
  • Train NFSP agents with feature-based observation
• python main.py --env 'PongDuel-v0' --obs_img both --evaluate --render --fgsm p1 --plot_fgsm
  • Attack the left-hand side trained image-based NFSP agent using FGSM and plot the perturbed observation
• python main.py --env 'PongDuel-v0' --obs_opp both --fgsm_training
  • Adversarial training on NFSP
