Requirements

• Python 3
• PyTorch and TorchVision (Tested under torch==1.3.0, torchvision==0.4.1)
• OpenAI baselines

In order to install requirements, follow:

# PyTorch
conda install pytorch torchvision -c soumith

# Other requirements
pip install -r requirements.txt

# Baselines for Atari preprocessing
git clone https://github.com/openai/baselines.git
cd baselines
pip install -e .
pip install gym[atari] 

Training

Train single-task A2C agent with self-supervised attention module.

Train with default config

The default config experiments/atari/a2c_mspacman_selfatt_thre1e-2_clsag1e-3.yaml provides the training config for env MsPacmanNoFrameSkip-v4, with hyper-parameters: sparsity penalty=1e-3, reconstruction threshold=1e-2.

# change to your config file
config=experiments/atari/a2c_mspacman_selfatt_thre1e-2_sparsity1e-3.yaml
python main.py --cfg $config
