獲取服務器API版本時Docker錯誤

Question

我在玩OpenAI的宇宙，當我點擊運行時，它出現了一個錯誤。

當前腳本：

import gym 
import universe # register the universe environments 

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

如果我刪除observation_n變量，也不會拿出一個錯誤。使用observation_n會導致錯誤。現在我正在運行docker-py (1.10.3)。

Answer 1

在程序中添加一行gym.make後如下，

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

保存。 現在打開兩個終端窗口。在第一種類型中，

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

一些亂碼會開始出現。現在，直到那個東西是怎麼回事，在您使用命令打開蟒蛇環境在下一個窗口中，

source activate universe 

然後你運行Python代碼，蟒蛇「路徑名」 /「程序名」的.py
