1.使用自带工具安装

依次打开菜单：File->Setting

点击+号，搜索torch

选择1.13.0版本安装

安装错误：

具体包含很长一段错误记录，如下：

2.使用pip命令安装

从上面我们可以看到whl文件的下载地址以及文件大小，具体为：

https://files.pythonhosted.org/packages/ec/5e/88854e28b3cb1cd5439d13299bde21b85be810d8d43f3547d72094e05eba/torch-1.13.0-cp37-cp37m-win_amd64.whl (167.3MB)

我们按照这个地址将文件下载下来，然后使用pip命令安装。

其他版本Torch和Torchvision地址：https://download.pytorch.org/whl/torch_stable.html

（1）将torch-1.13.0-cp37-cp37m-win_amd64.whl 文件复制到编译器路径下

具体地址为：C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Scripts

定位到pycharm中使用的编译器地址：

这是默认的地址，如果是新设置项目的地址就选择对应的新地址。

（2）'win+r' 输入cmd

输入：cd C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Scripts

指定安装路径

输入命令：pip install torch-1.13.0-cp37-cp37m-win_amd64.whl

安装成功以后：

3.运行测试

安装好之后，缺失的包提示波浪线不显示，表示安装成功了。

‘import torch_optimizer as optim’改为‘import torch.optim as optim’

from torchsummary import summary中的torchsummary单独安装

补充：torch和torchvision版本对应关系：以win py37m 为例

torch1.12.0–torchvision-0.13.0

torch1.12.1–torchvision-0.13.1

torch1.13.0–torchvision-0.14.0

torch1.13.1–torchvision-0.14.1
