  The sample inefficiency of standard deep reinforcement learning methods
precludes their application to many real-world problems. Methods which leverage
human demonstrations require fewer samples but have been researched less. As
demonstrated in the computer vision and natural language processing
communities, large-scale datasets have the capacity to facilitate research by
serving as an experimental and benchmarking platform for new methods. However,
existing datasets compatible with reinforcement learning simulators do not have
sufficient scale, structure, and quality to enable the further development and
evaluation of methods focused on using human examples. Therefore, we introduce
a comprehensive, large-scale, simulator-paired dataset of human demonstrations:
MineRL. The dataset consists of over 60 million automatically annotated
state-action pairs across a variety of related tasks in Minecraft, a dynamic,
3D, open-world environment. We present a novel data collection scheme which
allows for the ongoing introduction of new tasks and the gathering of complete
state information suitable for a variety of methods. We demonstrate the
hierarchality, diversity, and scale of the MineRL dataset. Further, we show the
difficulty of the Minecraft domain along with the potential of MineRL in
developing techniques to solve key research challenges within it.
