网上很多用pycharm的，但我是vscode的死忠粉(●'◡'●)
vscode上的python配置是之前就弄好的，所以先整好能跑“ print("hello world") ”哈

可见，我建了一个名为pytorch的环境。

问题一：找不到torch模块

创建一个pytorch.py文件,输入：

import torch

报错：

解决办法：

将settings.json文件改为如下内容，注意其中的python项改成自己python的地址

问题二：mkl-service模块导入失败blabla

和问题一相同的代码

出现很长很长的报错：

解决办法：

是环境变量配置的问题，这边困扰我很久。
因为在安装anaconda时点了自动配环境变量，我一直默认自己环境变量没问题。
