linux 安装pytorch报错

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64/current_repodata.json>
Elapsed: -An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
'https//mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64'

这大概是安全的问题，你的conda源使用的是https协议，比如我的
“/home/fcgna_xcb/.condarc”
内容如下：

channels:- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/fastai/- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
show_channel_urls: true
ssl_verify: false

把每一个https改成http就可以了
更改后的如下：

channels:- http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/- http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/- http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/- http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/- http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/fastai/- http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/- http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
