1、创建一个虚拟环境
conda create -n pytorch python=3.10安装成功：
但是使用上面的命令会失败（疑问？），使用下面的这个可以：
source activate pytorch
如果版本太高会报这个错：
Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
Solving environment: failed

To search for alternate channels that may provide the conda package you're
looking for, navigate to

and use the search bar at the top of the page.
2、配置安装PyTorch命令
PyTorch
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu -i https://mirrors.bfsu.edu.cn/pypi/web/simple --trusted-host mirrors.bfsu.edu.cn其中-i https://mirrors.bfsu.edu.cn/pypi/web/simple --trusted-host mirrors.bfsu.edu.cn是临时切换pip3下载源，其他部分都是从PyTorch官网配置后复制的。
安装成功截图：
3、验证pip3 list
import torch
print(torch.__version__)
成功打印出了版本号就说明安装成功啦。
