Each directory contains a script directory within it. The script within script directory was used to run experiments for this study. All the scripts are highly configurable. Change the parameter according to your needs.

Running Experiments on Atari

$ cd atari
$ sbatch scripts/train_atari.sh

Running Experiments on D4RL

For DT and BC, use

$ cd gym
$ sbatch scripts/train_gym.sh

For CQL, use

$ cd gym
$ sbatch scripts/train_cql.sh

Running Experiments on Robomimic

$ cd robomimic
$ sbatch scripts/train_default.sh

These scripts will create five directories named 1, 2, etc. depending on the number of seed provided. Each of these directory will contain a result.json file. Each directory is accompanied by read_data.py or read_data_cql.py. After the results are dumped, these scripts can be used to get the average mean and std dev from all the runs.
