Requirements

The code was run on a GPU with CUDA 10.2. To install all the required dependencies:

conda create -n auto-drac python=3.7
conda activate auto-drac

git clone git@github.com:rraileanu/auto-drac.git
cd auto-drac
pip install -r requirements.txt

git clone https://github.com/openai/baselines.git
cd baselines 
python setup.py install 

pip install procgen

Instructions

cd auto-drac

Train DrAC with crop augmentation on BigFish

python train.py --env_name bigfish --aug_type crop

Train UCB-DrAC on BigFish

python train.py --env_name bigfish --use_ucb

Train RL2-DrAC on BigFish

python train.py --env_name bigfish --use_rl2

Train Meta-DrAC on BigFish

python train.py --env_name bigfish --use_meta

Procgen Results

UCB-DrAC achieves state-of-the-art performance on the Procgen benchmark (easy mode), significantly improving the agent's generalization ability over standard RL methods such as PPO.

This code was based on an open sourced PyTorch implementation of PPO.

We also used kornia for some of the augmentations.
