当我尝试从此处运行以下示例代码时，Python 无法找到该remote_manager属性。我已经安装了所有必需的软件包，并且OpenAI 健身房示例似乎可以正常工作。
我在 Linux Mint 18 下运行 Python 3.5，并从 pip 存储库中获得了 OpenAI Gym 和 Universe。
import gym
import universe # register Universe environments into Gym
env = gym.make('flashgames.DuskDrive-v0') # any Universe environment ID here
observation_n = env.reset()
while True:
# agent which presses the Up arrow 60 times per second
action_n = [[('KeyEvent', 'ArrowUp', True)] for _ in observation_n]
observation_n, reward_n, done_n, info = env.step(action_n)
env.render()
完整的堆栈跟踪是
