PyTorch implementation of Proximal Policy optimization

PyTorch implementation of Proximal Policy optimization (PPO), Proximal Policy Optimization Algorithms.

Installation

Clone GitHub repository and set up environment

git clone https://github.com/burchim/PPO-PyTorch.git && cd PPO-PyTorch
pip install -r requirements.txt

Training

Train agent on a specific task:

env_name=atari-breakout python3 main.py -c configs/PPO/ppo.py

Train agent on all tasks:

./train_ppo_atari.sh

Visualize experiments

tensorboard --logdir ./callbacks

Overriding model config hyperparameters

override_config='{"dim_cnn": 48, "eval_env_params": {"episode_saving_path": "./videos"}}' run_name=dim_cnn_48 env_name=atari-breakout python3 main.py -c configs/PPO/ppo.py

Evaluation

env_name=atari-breakout python3 main.py -c configs/PPO/ppo.py --mode evaluation

Atari Results (40M env steps)

We averaged the evaluation score over 10 episodes.
