This repo contains code for learning reward functions and state weights from preferences. After installation, find the task to run in main.py. For example,

python -um crowd_pbrl.main --exp_path <path-to-experiments> --gpu_id 0 --split 1 --game BeamRider --task sample_trajectories --method bt

Samples some trajectories for reward learning. Make sure there is a config.gin file in your . An example for configuration file is provided as config.gin. A script for how one can run experiments on Enduro is provided as run.py.
