打开ai体育馆Nameerror [英] open ai gym Nameerror

问题描述

我试图在WSL上使用来自OpenAI的著名的"Gym"模块，并在python 3.5.2上执行代码.当我尝试运行环境如此处所述时，使用以下代码:

I am trying to use the famous 'Gym' module from OpenAI on WSL and executing code on python 3.5.2. When I try to run an environment as explained here, using the code:

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

这发生了:

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/.local/lib/python3.5/site-packages/pyglet/gl/__init__.py", line 224, in <module>
    del base

推荐答案

这可能不是这个问题的完美答案，但这是我解决该问题的经验.

This may not be a perfect answer to this question but this is my experience how I resolved this problem.

从spyder运行程序时遇到相同的错误.但是当我从终端执行相同的代码时，它没有引发任何错误. 但要针对健身房环境正确配置您的语言环境.

I was getting the same error when I running my programme from the spyder. but when I execute the same code from the terminal it didn't throw any error. but make your locale is correctly configured for the gym environment.
