如何在google colab中安装并运行gym box2d环境？

Question

我已经按照这个方法运行box2d环境，而无需在google colab中渲染它，

!apt-get install python-box2d
!pip install box2d-py
!pip install gym[Box_2D]
import gym
env = gym.make("BipedalWalker-v2")

但是它显示了这个

我也尝试从 pip 安装此 box2d

pip install Box2D

但它没有安装在 colab 中。我们如何在 google colag 中安装并运行 box2d 健身房环境？

Answer 1

我能够让它与

!pip3 install box2d-py==2.3.8

一起工作。

Answer 2

请创建一个新的 Colab 笔记本，点击文件 -> 新建笔记本。在新的（新的）Colab 上执行这些：

!pip3 install box2d-py
!pip3 install gym[Box_2D]
import gym
env = gym.make("BipedalWalker-v3")

新笔记本中默认安装了gym，但是您必须安装box2d-py 和gym[Box_2D]。如果遇到错误，请关闭当前笔记本。只需使用新笔记本（非常重要）并继续执行上述 pip install 过程即可。会起作用的！

Answer 3

这对我有用。在运行这些代码之前，请确保在 Google Colab 笔记本中重新启动运行时：

!pip install gymnasium
!pip install box2d

然后在另一个单元格中运行此

import gym
import gymnasium
env = gym.make("LunarLander-v2")

希望这有帮助！

Answer 4

我遇到了同样的问题。贝娄为我工作。

!pip install swig
!pip install gymnasium
!pip install gym[box2d]
