 Dreamer is an image-only model-based RL method that learns by imagining trajectories in the future and is evaluated on the DeepMind Control Suite `environments <https://github.com/ray-project/ray/blob/master/rllib/examples/env/dm_control_suite.py>`__. RLlib's Dreamer is adapted from the `official Google research repo <https://github.com/google-research/dreamer>`__.
