我正在玩 OpenAI 的宇宙，当我单击运行时，它会出现错误。

当前脚本：

import gym
import universe  # register the universe environments

env = gym.make('flashgames.CoasterRacer-v0')
observation_n = env.reset()

如果我删除observation_n 变量，它不会出现错误。使用observation_n 会导致错误。现在我正在跑步docker-py (1.10.3)。

在您的程序中，在 gym.make 之后添加一行，如下所示，

env = gym.make('flashgames.DuskDrive-v0')
env.configure(remotes="vnc://localhost:5900+15901")
observation_n = env.reset()

保存。现在打开两个终端窗口。在第一种类型中，

sudo docker run -p 5900:5900 -p 15901:15901 --privileged --cap-add SYS_ADMIN --ipc host quay.io/openai/universe.flashgames:0.20.7

一些乱码将开始出现。现在直到事情发生，在下一个窗口中你使用命令打开你的 anaconda 环境，

source activate universe

然后你运行你的python代码，python“path_name”/“program_name”.py
