Stable-Baselines3 是基于 PyTorch 框架开发的1。 Stable-Baselines3 主要用于什么领域? Stable-Baselines3 主要用于强化学习算法的实现和研究领域,它为研究和开发人员提供了一个简单、高效的方式来训练和使用强化学习算法1。 如何在 Stable-Baselines3 中实现一个基本的强化学习算法?
pip install stable_baselines3 针对需要自己搭建环境的用户来说,gym模块也是必不可少的,因为stable_baseline中的强化学习环境就是针对gym框架进行开发的 pip install gym 2、环境搭建 基于gym的环境模型一般都可以写成这样: # _*_coding:utf-8-*- import sys ...
