OpenAIユニバースの例を実行すると、 'VNCEnv'オブジェクトに属性 'remote_manager'がありません

Question

hereから次のサンプルコードを実行しようとすると、Pythonはremote_manager属性を見つけることができません。必要なパッケージがすべてインストールされていて、OpenAI gym examplesが正常に動作するように見えます。

私はLinux Mint 18でPython 3.5を実行しています.PipリポジトリからOpenAIジムとユニバースを取得しました。

import gym 
import universe # register Universe environments into Gym 

env = gym.make('flashgames.DuskDrive-v0') # any Universe environment ID here 
observation_n = env.reset() 

while True: 
    # agent which presses the Up arrow 60 times per second 
    action_n = [[('KeyEvent', 'ArrowUp', True)] for _ in observation_n] 
    observation_n, reward_n, done_n, info = env.step(action_n) 
    env.render() 

フルスタックトレースあなたはenv.configure（呼び出すのを忘れて

です）

env = gym.make('flashgames.DuskDrive-v0') 
env.configure(remotes=1) 
observation_n = env.reset()
