获取服务器API版本时Docker错误
我正在玩OpenAI的宇宙，当我点击运行，它出现了一个错误。
当前脚本：
import gym import universe # register the universe environments env = gym.make('flashgames.CoasterRacer-v0') observation_n = env.reset() 如果我删除了observation_nvariables，它将不会出现错误。 随着observation_n它会导致一个错误。 现在我正在运行docker-py (1.10.3) 。

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terminal窗口。 在第一种types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。 现在直到那个事情发生，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
