1、conda 切换虚拟环境
activate 虚拟环境名称C:\Windows\System32>activate python310温馨提示：查询虚拟环境列表
conda env listC:\Windows\System32>conda env list
# conda environments:
#
base D:\anaconda3
python310 D:\anaconda3\envs\python310
2、conda 查看安装源
conda config --show-sources我本地安装源为:清华大学开源软件镜像源
修改conda 默认安装源，请执行如下指令:
# 安装清华安装源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
# 移除conda 默认安装源
conda config --remove channels defaults3、conda 查看PyTorch版本
conda search pytorch(python310) C:\Windows\System32>conda search pytorch
Loading channels: done

根据自己的安装版本，在Pytorch官网寻找安装命令代码：
（1）Pytorch官网：PyTorch
如图所示版本将相关指令复制：
conda install pytorch torchvision torchaudio cpuonly -c pytorch（2）将复制的代码粘贴到命令行格式下，弹出提示，输入 y，即可完成安装，显示“done”。
(python310) C:\Windows\System32>conda install pytorch torchvision torchaudio cpuonly -c pytorch
