Learning with Opponent-Learning Awareness

Implements the LOLA (AAMAS'18) and LOLA-DiCE (ICML'18) algorithms.

Further resources:

• A pytorch implementation of LOLA-DiCE is available at https://github.com/alexis-jacq/LOLA_DiCE.
• A colab notebook with the nummerical evalution for DiCE is available at https://goo.gl/xkkGxN.

Installation

To run the code, you need to pip-install it as follows:

$ pip install -e .

After installation, you can run different experiments using the run scripts provided in scripts/. Use run_lola.py and run_tournament.py for running experiments from the AAMAS'18 paper. Use run_lola_dice.py for reproducing experiments from the ICML'18 paper. Check out notebooks/ for IPython notebooks with plots.

Note: this code is not tested on GPU, so there might be unexpected issues.

Disclaimer: This is a research code release that has not been tested beyond the use cases and experiments discussed in the original papers.

Contribution

Contributions to further enhance and improve the code are welcome. Please email jakob.foerster at cs.ox.ac.uk and alshedivat at cs.cmu.edu with comments and suggestions.
