新版的scipy不兼容，把scipy降低版本，
方法尝试
1. 在cmd中运行如下命令：pip install -i https://pypi.tuna.tsinghua.edu.cn/simple scipy==1.2.1 --upgrade
WARNING: You are using pip version 21.2.4; however, version 21.3.1 is available.
You should consider upgrading via the 'd:\anaconda\anaconda3\python.exe -m pip install --upgrade pip' command.
2. pip install scipy==1.2 --upgrade
执行两遍，第一遍把原有库文件uninstall，第二遍安装1.2版本，实现downgrade
Requirement already satisfied: scipy==1.2 in d:\anaconda\anaconda3\lib\site-packages (1.2.0) Requirement already satisfied: numpy>=1.8.2 in d:\anaconda\anaconda3\lib\site-packages (from scipy==1.2) (1.21.2)
WARNING: You are using pip version 21.2.4; however, version 21.3.1 is available. You should consider upgrading via the 'd:\anaconda\anaconda3\python.exe -m pip install --upgrade pip' command.
