语法错误:在repl.it上打印yaml.dump(

标签: python repl.it

我需要帮助纠正这个错误,我一直在repl.it中遇到错误,这是错误,我将其分解为关键要素:

Traceback (most recent call last):
  File "python", line 3, in <module>
  File "/home/runner/.site-packages/universe/__init__.py", line 227
    print yaml.dump(
             ^
SyntaxError: invalid syntax

这是我使用的代码(我在repl.it中创建了它):

import gym
import universe

env = gym.make('flashgames.CoasterRacer-V0')
observation_n = env.reset()

while True:
  observation_n = [[('KeyEvent', 'ArrowUp', True)] for ob in observation_n]
  observation_n, reward_n, done_n, info = env.step(action_n)
  env.render()

你能帮我吗?

该错误似乎表明universe仅是Python 2。
