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

PackagesNotFoundError: The following packages are not available from current channels:

  - python=3.12.5

Current channels:

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

    https://anaconda.org

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。

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。
