AttributeError: 'TimeLimit' object has no attribute 'monitor'

原報錯代碼部分：
    env.monitor.start(monitor_path,
                  resume=True,
                  video_callable=lambda count: count % record_video_every == 0)

reason:
    env.monitor is deprecated. Wrap your env with gym.wrappers.Monitor to record data.

所以改為 env = Monitor()
注意：1.加from gym.wrappers import monitor
     2.Monitor（）內部參數要改為Monitor(env, directory=monitor_path,其他直接寫)
