Lunarlander-v2-C51

Play LunarLander-v2 with C51 Policy

Model Description

<!-- Provide a longer summary of what this model is. -->

This is a simple C51 implementation to OpenAI/Gym/Box2d LunarLander-v2 using the DI-engine library and the DI-zoo.

DI-engine is a python library for solving general decision intelligence problems, which is based on implementations of reinforcement learning framework using PyTorch or JAX. This library aims to standardize the reinforcement learning framework across different algorithms, benchmarks, environments, and to support both academic researches and prototype applications. Besides, self-customized training pipelines and applications are supported by reusing different abstraction levels of DI-engine reinforcement learning framework.
