我正在尝试使用OpenAI编写以下代码:
import gym
env = gym.make('CarRacing-v0')
env.reset()
for _ in range(1000):
env.render()
env.step(env.action_space.sample())
但是它抛出了以下错误:
fn = getattr(mod, attr_name) AttributeError: 模块 'gym.envs.box2d' 没有属性 'CarRacing'
然后我尝试通过 pip install box2d-py 安装 box2d,但是抛出了以下错误:

我该怎么做才能成功安装它?
swig.exe
,所以你可能需要 http://www.swig.org/index.php - furaspip install Box2d
即可。这对我有效。 - Roy
