解决：Collecting package metadata (current
安装Pytorch时报错：

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 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.

- 尝试指定各个包的版本，失败

- 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 cmd_line
