📦 Install -- Install relevant dependencies and the project
🔧 Usage -- Commands to run different experiments from the paper

Install

To install the requirements, follow these steps:

# PyTorch
conda install pytorch torchvision -c pytorch
export LC_ALL=C.UTF-8
export LANG=C.UTF-8

# Install requirements
pip install -r requirements.txt

# Finally, clone the project
git clone https://github.com/mila-iqia/spr

Usage:

The default branch for the latest and stable changes is release.

To run SPR with augmentation

python -m scripts.run --public --game pong --momentum-tau 1.

To run SPR without augmentation

python -m scripts.run --public --game pong --augmentation none --target-augmentation 0 --momentum-tau 0.01 --dropout 0.5

When reporting scores, we average across 10 seeds.
