我已经跟随this method运行了一个box2d环境，而没有在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")

但它显示了这个

我也试着从pip pip install Box2D安装这个box2d，但它没有安装在colab中。如何在google colag中安装和运行box2d gym环境？

python-3.x

我可以用!pip3 install box2d-py==2.3.8来实现它。

请创建一个新的Colab笔记本，点击文件-〉新建笔记本。在新的（新鲜的）Colab上执行以下操作：

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

gym默认安装在新笔记本中，但是您必须安装box 2d-py和gym[Box_2D]。如果遇到错误，请关闭当前笔记本。只需使用一个新的笔记本电脑（非常重要），并继续上述程序的pip安装。会成功的！

这对我很有效。在运行这些代码之前，请确保在Google Colab notebook中重新启动运行时：

!pip install gymnasium
!pip install box2d

然后在另一个细胞中运行这个

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

希望这有帮助！
