Our paper is up on arXiv.
Official codebase for Can Wikipedia Help Offline Reinforcement Learning?. Contains scripts to reproduce experiments. (This codebase is based on that of https://github.com/kzl/decision-transformer)
We provide code our code directory containing code for our experiments.
Experiments require MuJoCo. Follow the instructions in the mujoco-py repo to install. Then, dependencies can be installed with the following command:
conda env create -f conda_env.yml
Datasets are stored in the data directory. LM co-training and vision experiments can be found in lm_cotraining and vision directories respectively.
Install the D4RL repo, following the instructions there.
Then, run the following script in order to download the datasets and save them in our format:
python download_d4rl_datasets.py
ChibiT can be downloaded with gdown as follows:
gdown --id $ID #we will add it soon!Experiments can be reproduced with the following:
python experiment.py --env hopper --dataset medium --model_type dt --pretrained_lm gpt2 \ # or path to chibiT
--gpt_kmeans --gpt_kmeans-const 0.1
--
The run.sh file has example commands.
Adding -w True will log results to Weights and Biases.
