(这篇博客适用于 gym 的接口,gymnasium 接口也差不多,只需详细看看接口定义 魔改一下即可) 安装openai gym: # pip install gym import gym from gym import spaces 需实现两个主要功能: env.__init__() 和obs = env.reset() 函数; obs, reward, done, info = env.step(action) 函数。 01 env 的初...
pip install gymnasium 1. 接下来,启动一个环境。不过,您可以创建自定义环境。但是,要想掌握OpenAI Gym概念,应先从现有的环境开始。 下面的代码启动FrozenLake-v1。env.reset方法记录了初始观察结果: 复制 importgymnasiumasgym env=gym.make('FrozenLake-v1',render_mode="human")observation,info=env.reset() 1...
classic_control(这个需要 pyglet 模块) 如果在安装中遇到问题. 可能是缺少了一些必要模块, 可以使用下面语句来安装这些模块(安装时间可能有点久): #MacOS:$brew install cmake boost boost-python sdl2 swig wget#Ubuntu 14.04:$apt-get install -y python-numpy python-dev cmake zlib1g-dev libjpeg-dev xvfb...
The team that has been maintaining Gym since 2021 has moved all future development toGymnasium, a drop in replacement for Gym (import gymnasium as gym), and Gym will not be receiving any future updates. Please switch over to Gymnasium as soon as you're able to do so. If you'd like to...

pip安装gymnasium之后。出现问题: gymnasium.error.DependencyNotInstalled:Box2Dis not installed, run `pip install gymnasium[box2d]` 但是运行`pip install gymnasium[box2d]`又报错: ERROR: Could not build wheels for box2d-py, which is required to install pyproject.toml-based projects ...
import gymnasium as gym from gym_idsgame.envs import IdsGameEnv env_name = "idsgame-maximal_attack-v3" env = gym.make(env_name)The environment ships with implementation of several baseline algorithms, e.g. the tabular Q(0) algorithm, see the example code below....
我们的自定义环境将继承抽象类gymnasium.Env。您不应该忘记将meta元数据属性添加到类中。在那里,您应该指定环境支持的render_mode(例如“human”、“rgb_array”、“ansi”)以及渲染环境的帧速率。每个环境都应该支持None作为渲染模式;您不需要将其添加到元数据中。在GridWorldEnv中,我们将支持“rgb_array”和“human...
代码对gym、0.18.0和0.19.0有效，但对0.20.0无效您可以使用对于在2023中使用新Gymnasiumfork的任何...
pip install gymnasium Next, spin up an environment. You can create a custom environment, though. But start by playing around with an existing one to master the OpenAI Gym concept. The code below spins up theFrozenLake-v1. Theenv.resetmethod records the initial observation: ...
