代码报错：在配置好conda环境以及将该项目fork到本地后，在运行DI-engine/dizoo/petting_zoo/config/路径下的所有py文件（如ptz_simple_spread_madqn_config.py；ptz_simple_spread_mappo_config.py等）时均出现报错

报错信息具体如下： Traceback (most recent call last): File "E:\mypycharmprojects\DI-Engine-for-DTDE-MARL\ding\envs\env_manager\base_env_manager.py", line 137, in init self._observation_space = self._env_ref.observation_space File "E:\mypycharmprojects\DI-Engine-for-DTDE-MARL\dizoo\petting_zoo\envs\petting_zoo_simple_spread_env.py", line 305, in observation_space return self._observation_space AttributeError: 'PettingZooEnv' object has no attribute '_observation_space'

During handling of the above exception, another exception occurred:

请提供一下你本地的pettingzoo版本

[QingYuanZi1024]

1.23.1

[PaParaZz1]

也许你可以降版本到 1.22.3 试一下，我们之前的实验最高用到的是这个版本
