每当我尝试在 Universe 上运行程序时，都会在套接字关闭的地方收到此错误。我不知道如何解决它，而且我已经搞砸了很多年。我正在使用 openAI 提供的示例代码，但由于某种原因，Flash 游戏没有按预期加载。有什么建议么？
顺便说一下，我正在关注https://github.com/openai/universe给出的 python 代码。这是：
import gym
import universe # register the universe environments
env = gym.make('flashgames.DuskDrive-v0')
env.configure(remotes=1) # automatically creates a local docker container
observation_n = env.reset()
while True:
action_n = [[('KeyEvent', 'ArrowUp', True)] for ob in observation_n] # your agent here
observation_n, reward_n, done_n, info = env.step(action_n)
env.render()
这是我尝试运行它时得到的错误日志。我不完全确定出了什么问题以及如何解决它。
