ImportError: sys.meta_path is None, Python is likely shutting down

您好，我最近也在看《深入浅出强化学习：原理入门》我在window10环境下，按照书上的步骤和按照您给gym二次开发相关文件配置的进行操作，
却总是会遇到系统路径的问题，请问您是怎么解决的呀。
下面是我根据做完相关文件的配置后，运行1-gym_developing/grid_game.py 文件所给出的错误，烦请您看一下
C:\ProgramData\Anaconda3\python.exe D:/zCoding/Coding/RLlearn/Basic_Book_Code/1-gym_developing/grid_game.py Exception ignored in: <bound method Viewer.__del__ of <gym.envs.classic_control.rendering.Viewer object at 0x000002475EE431D0>> Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\site-packages\gym\envs\classic_control\rendering.py", line 143, in __del__ File "C:\ProgramData\Anaconda3\lib\site-packages\gym\envs\classic_control\rendering.py", line 62, in close File "C:\ProgramData\Anaconda3\lib\site-packages\pyglet\window\win32\__init__.py", line 305, in close File "C:\ProgramData\Anaconda3\lib\site-packages\pyglet\window\__init__.py", line 770, in close ImportError: sys.meta_path is None, Python is likely shutting down

您好 还一个问题，在运行2-markov_decision_process/game.py文件是有个元祖和int类型比较的地方，这里是不是作者写错了啊，请问您是怎么修改的呢
File "C:\ProgramData\Anaconda3\lib\site-packages\gym\envs\classic_control\maze_game.py", line 58, in _reward if (0 <= n_s).all() and (n_s <= 4).all() and \ TypeError: '<=' not supported between instances of 'int' and 'tuple'

你直接运行文件时不对的，你需要在python文件中添加下面语句去运行环境
import gym env = gym.make("GridGame-v0") env.reset() env.render()

你说的第二个问题我已经修改上传了，很感谢你给我指出问题。
