Setup

pip3 install --user tensorflow-gpu==2.2.0
pip3 install --user tensorflow_probability
pip3 install --user git+git://github.com/deepmind/dm_control.git
pip3 install --user pandas
pip3 install --user matplotlib

You will need the Mujoco license to run the Mujoco tasks.

To play with the natural Mujoco tasks, download the natural Mujoco background dataset from here and put it at the root of this folder.

Train the agent:

python3 cvrl.py --logdir ./logdir/dmc_walker_walk/natural_walker_walk/1 --task dmc_walker_walk --natural True --obs_model contrastive --use_dreamer True --use_sac True --trajectory_opt True

To view the training logs and execution videos, please use

tensorboard --logdir ./logdir --bind_all
