Python-健身房。看不到环境

Question

请告诉我可能是什么问题？
只有一个环境正确启动。（手推车）

import gym
env = gym.make('CarRacing-v0')
env.reset()
for _ in range(1000):
    env.render()
    env.step(env.action_space.sample())

AttributeError Traceback (most recent call last) in () 1 import gym ----> 2 env = gym.make('CarRacing-v0') 3 env.reset() 4 for _ in range(1000): 5 env.render()

Answer 1

我用的不是 anaconda，而是 virtualenv。尽管如此，我最初还是犯了同样的错误。 "Classical" 环境似乎在工作，但 Box2D 游戏却没有。我尝试使用 "pip install Box2D" 单独安装 Box2D，但在安装依赖项 "wheel".

时收到缺少 swig.exe 的错误

要解决这个问题，

我下载了 swig，然后将 swig.exe 的路径添加到我的 windows 路径中。
然后我卸载了gym和Box2D
然后我安装了 gym，然后安装了 Box2D "pip install gym[box2d]"
