Installation

Manual

Warning

Unfortunately, installing all dependencies can cause some difficulties at the moment, mainly due to **D4RL** and 
the old version of mujoco it is locked to. It will be much easier in the future after migration to the **Minari** is done.

All necessary dependencies are specified in the requirements/requirements.txt file. You can just clone the repo and install all dependencies with pip:

git clone https://github.com/corl-team/CORL.git
cd CORL
pip install -r requirements/requirements.txt

In addition to those specified there, the dependencies required by D4RL, namely MuJoCo binaries, must also be installed. We recommend following the official guide from mujoco-py. You will need to download MuJoCo 2.1 binaries and extract downloaded mujoco210 directory to the ~/.mujoco/mujoco210:

mkdir -p ~/.mujoco \
    && wget https://mujoco.org/download/mujoco210-linux-x86_64.tar.gz -O mujoco.tar.gz \
    && tar -xf mujoco.tar.gz -C ~/.mujoco \
    && rm mujoco.tar.gz
export LD_LIBRARY_PATH=~/.mujoco/mujoco210/bin:${LD_LIBRARY_PATH}

If you have any problems with the installation, we advise you to first look for similar issues in the original D4RL and mujoco-py repositories. Most likely problem is in D4RL, not in CORL

Docker

To simplify installation and improve reproducibility, we provide a preconfigured Dockerfile that you can use:

cd CORL
docker build -t corl .
docker run --gpus=all -it --rm --name corl-container corl
