gymis a suite of virtual environments provided by OpenAI, to test reinforcement learning algorithms on. The suite contains everything from simple text games, to retro Atari games, to even 3D physics simulators. For this project, I apply the MuZero algorithm to the cart pole environment. The go...

以上代码首先导入gym库,第2行创建CartPole-v0环境,并在第3行重置环境状态。在for循环中进行1000个时间步长(timestep)的控制,第5行刷新每个时间步长环境画面,第6行对当前环境状态采取一个随机动作(0或1),最后第7行循环结束后关闭仿真环境。 结果分析
学了这么多理论内容,我们终于要开始进行实践了,我们先从最简单的 gym倒立摆环境开始吧(之后会有更复杂的环境,也会自己编写环境) 所有文章和代码(如果有的话)会在知乎和Github上同步捏。 上一篇文章:从零开始の深度强化学习--学习笔记(07) 安装环境 (下文终端均为 windows 终端) ...

Description A pole is attached by an un-actuated joint to a cart, which moves along a frictionless track. The pendulum starts upright, and the goal is to prevent it from falling over by increasing and reducing the cart's velocity.

基本环境可以参考:https://gym.openai.com/envs/CartPole-v1/ 以及https://github.com/PaddlePaddle/PARL/tree/develop/examples/DQN 学习的目标是使得木棍在小车上树立的时间尽量长。action的选择只有向左或者是向右。环境会自动给出给出反馈,每一步后的得分,下一个局面的描述的状态,是否是结束。环境状态被gym自...
