'VNCEnv' Objekt hat kein Attribut 'remote_manager' beim Ausführen von OpenAI-Universum Beispiel

Question

Wenn ich versuche, den folgenden Beispielcode von here auszuführen, kann Python das remote_manager Attribut nicht finden. Ich habe alle erforderlichen Pakete installiert und die OpenAI gym examples scheinen zu funktionieren, wie sie sollten.

Ich habe Python 3.5 unter Linux Mint 18, und ich habe OpenAI Gym und Universum aus den Pip-Repositories.

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() 

Der vollständige Stacktrace ist

Answer 1

Sie haben vergessen env.configure zu nennen()

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