stable-baselines3学习之自定义策略网络(Custom Policy Network) stable-baselines3为图像 (CnnPolicies)、其他类型的输入特征 (MlpPolicies) 和多个不同的输入 (MultiInputPolicies) 提供policy networks。 1.SB3 policy SB3网络分为两个主要部分: 一个特征提取器(通常在适用时在actor和critic之间共享),作用是从高维ob...

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 ...
