 This repo implements the Dreamer algorithm from [Dream to Control: Learning Behaviors By latent Imagination](https://arxiv.org/pdf/1912.01603.pdf) based on the [PlaNet-Pytorch](https://github.com/Kaixhin/PlaNet). It has been confirmed working on the DeepMind Control Suite/MuJoCo environment. Hyperparameters have been taken from the paper.
