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

原报错代码部分：
    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.

所以改为 env = Monitor()
注意：1.加from gym.wrappers import monitor
     2.Monitor（）内部参数要改为Monitor(env, directory=monitor_path,其他直接写)
