python - openAi-gym 名称错误

Question

我正在尝试在 WSL 上使用来自 OpenAI 的著名“健身房”模块，并在 python 3.5.2 上执行代码。
当我尝试运行环境时 as explained here ，使用代码:

import gym
env = gym.make('CartPole-v0')
for i_episode in range(20):
    observation = env.reset()
    for t in range(100):
        env.render()
        print(observation)
        action = env.action_space.sample()
        observation, reward, done, info = env.step(action)
        if done:
            print("Episode finished after {} timesteps".format(t+1))
            break

发生这种情况:

Traceback (most recent call last):
  File "<stdin>", line 4, in <module>
  File "/home/DrHofstadter/gym/gym/core.py", line 153, in render
    return self._render(mode=mode, close=close)
  File "/home/DrHofstadter/gym/gym/core.py", line 285, in _render
    return self.env.render(mode, close)
  File "/home/DrHofstadter/gym/gym/core.py", line 153, in render
    return self._render(mode=mode, close=close)
  File "/home/DrHofstadter/gym/gym/envs/classic_control/cartpole.py", line 114, in _render
    from gym.envs.classic_control import rendering
  File "/home/DrHofstadter/gym/gym/envs/classic_control/rendering.py", line 23, in <module>
    from pyglet.gl import *
  File "/home/DrHofstadter/.local/lib/python3.5/site-packages/pyglet/gl/__init__.py", line 224, in <module>
    del base
NameError: name 'base' is not defined

问题类似于this question什么都没有被渲染。 (有问题的 gitterforum 链接不再有效。)

这可能不是这个问题的完美答案，但这是我解决这个问题的经验。

当我从 spyder 运行我的程序时，我遇到了同样的错误。但是当我从终端执行相同的代码时，它没有抛出任何错误。但要为健身房环境正确配置您的语言环境。
