Docker 获取服务器 API 版本时出错

Question

我在玩OpenAI的宇宙，点击运行的时候报错

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。现在我运行宁 docker-py (1.10.3).

Answer 1

在你的程序中在gym.make后添加一行如下，

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windows。第一种，

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

将开始出现一些乱码。现在直到事情继续进行，在接下来的 window 你使用命令打开你的 anaconda 环境，

source activate universe

然后你运行你的 python 代码为 python "path_name"/"program_name".py
