环境依赖问题

[chenzheng135248]

你好，我在安装环境依赖的时候出现了一个冲突

`ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
gym-unity 0.28.0 requires gym==0.20.0, but you have gym 0.23.1 which is incompatible`

pettingzoo 和gym.unity 对于gym安装的版本不匹配，请问该怎么去解决。期待您的回复

你好，我们刚刚更新了这个包，请重新试一下。我看这个bug是由于gym版本不匹配导致的。请问是之前安装过gym吗？可以uninstall 了现有版本再重新安装试一下。

在COG-sim2real-challenge路径下，新建文件requirements.txt，把上面的复制到里面，然后打开conda环境，运行pip install -r requirements.txt
