Offline Meta-Reinforcement Learning with Advantage Weighting (MACAW)

MACAW code used for the experiments in the ICML 2021 paper.

Installing the environment

# Install Python 3.7.9 if necessary
$ pyenv install 3.7.9
$ pyenv shell 3.7.9

$ python --version
Python 3.7.9

$ python -m venv env
$ source env/bin/activate
$ pip install -r requirements.txt

Downloading the data

The offline data used for MACAW can be found here. Download it and use the default name (macaw_offline_data) for the folder where the four data directories are stored. gDrive might be useful here if downloading from the Google Drive GUI is not an option.

Running MACAW 🦜

Run offline meta-training with periodic online evaluations with any of the scripts in scripts/. e.g.

$ . scripts/macaw_dir.sh # MACAW training on Cheetah-Direction (Figure 1)
$ . scripts/macaw_vel.sh # MACAW training on Cheetah-Velocity (Figure 1)
$ . scripts/macaw_quality_ablation.sh # Data quality ablation (Figure 5-left)
...

Outputs (tensorboard logs) will be written to the log/ directory.
