导致问题的原因

与之前的变化

报错中
UnicodeDecodeError: ‘gbk’ codec can’t decode byte 0xaf in position 373: illegal multibyte sequence
首先我从ubuntu系统复制了文件放在win下之前的项目中了，或许跟文件解码有关。
所以先移除了这个文档。
但是还是不行，或许是spyder默认的编解码方式改变了，尝试reset

在powershell中

 spyder  --reset

不行

成功方法

在anaconda prompt 执行

spyder --reset C

(base) C:\Users\10928>spyder --reset C
