This is a contemporary PyTorch implementation of the Dreamer v1 algorithm, originally developed by Danijar Hafner et al. The original paper is accessible here.

This implementation draws heavily from the following projects:

• The original Dreamer v1 implementation
• dreamer-pytorch by Julius Frost
• dreamer-pytorch by Yusuke Urakami

The purpose of this project is solely for academic use.

Additionally, this project serves as a supplementary project for our CSC413 final project at the University of Toronto, where I am collaborating with the following wonderful people:

• Charlotte
• Blair
• Ray
