安装Pytorch时报错：

Collecting package metadata (current_repodata.json): - WARNING conda.models.version:get_matcher(556): Using .* with relational operator is superfluous and deprecated and will be removed in a future version of conda. Your spec was 1.7.1.*, but conda is ignoring the .* and treating it as 1.7.1

先说最后成功解决的办法：执行下面语句后，装pytorch, torchvision, torchaudio都成功安装了，一点不报错：

conda config --remove-key channels

再说说，踩过的坑：目标是在服务器上安装pytorch，先是创建了虚拟环境，安装cuda版本的pytorch时一直报错。尝试用下面的办法解决，都没有成功

最初直接安装，报错

(AE-base) sh-5.0$ conda install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia

done

尝试指定各个包的版本，失败

(AE-base) sh-5.0$ conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia

done

尝试删除**.condarc**，依旧不能成功安装

查看.condarc的位置，然后删除

(AE-base) sh-5.0$ conda config --show-sources

==> /home/XX/.condarc <==

channels:

- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch

- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2

- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r

- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

- defaults

- conda-forge

==> cmd_line <==

debug: False

json: False

更新包的版本后依旧不成功

conda update conda

conda update -all

执行下面命令依旧不成功

conda config --add channels conda-forge

conda config --set channel_priority flexible

改用pip安装，依旧不成功

pip3 install torch torchvision torchaudio

更新pip不成功

pip install --upgrade pip

添加http镜像，不成功
