This is the code for the paper Discovering Hierarchical Achievements in Reinforcement Learning via Contrastive Learning accepted to NeurIPS 2023.

conda create --name ad-crafter python=3.10
conda activate ad-crafter
pip install --upgrade "setuptools==65.7.0" "wheel==0.38.4" "pip==24.0"
pip install -r requirements.txt
pip install -e .

If you are working in a Bash environment, you can use the following commands. The system will set the timestamp to debug by default.

PPO

python train.py --exp_name ppo --log_stats --save_ckpt

PPO + Achievement Distillation (ours)

python train.py --exp_name ppo_ad --log_stats --save_ckpt

If you are working in an environment that utilizes the Slurm Workload Manager, you can submit your job using submit.py. In this setup, the system automatically assigns a timestamp that corresponds to the actual start time of your job.

If you want to evaluate an agent on a new environment, you can use the following command. This will create a video displaying the agent's behavior.

python eval.py --exp_name [your exp name] --timestamp [your timestamp]
