关于gym版本

[526766987]

gym版本过高会导致env加载报错，0.18.0用最新的pip是安装不上的。
可以尝试先请回退安装工具的版本，然后再安装旧版本的gym，具体方法见可以看这个帖子：

实测可以用此方法安装0.18.3，在0.18.3中项目可以正常运行。

Another option is to install Python 3.8 (assuming you are currently using a newer version) and then directly install gym==0.18.0. The specific steps are as follows:

Add deadsnakes repository

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update

Install python

sudo apt-get install python3.8
sudo apt-get install python3.8-venv

Create virtualenv

python3.8 -m venv venv
source ./venv/bin/activate

Test for python version

python # will return python3.8
pip install gym==0.18.0
