1.修改pip以及conda为国内源
pip.ini

[global]
index-url=https://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com

.condarc

2.创建conda环境

conda create -n pytorch python=3.8
conda info --env
conda install -n pytorch pylint

3.安装pytorch，不带GPU

conda install -n pytorch pytorch torchvision cpuonly

4.激活环境

activate pytorch
import torch
