首先说一下背景：我是在服务器里面跑项目，然后服务器网络的话用的代理proxy

一、下面是我遇到的错误

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1131)'))': /simple/transformers/

错误来源于命令

pip install PackageName

同样地，错误也出现在conda上。

随后，我惊奇的发现，只有在我所创的环境里下载包才会有这样的问题，在base环境里完全可以下载包，一点问题都没有！！！

遇到的第二个问题：大概就是说，有时候pip不行要用conda 而且可能还要在后面加-c pytorch
今天就是这样，最后成功的命令是

conda install pytorch=1.10.0 torchvision=0.11.1 cudatoolkit=10.2 -c pytorch

不加**-c pytorch**会报错，用 pip 好像也会报错，挺奇怪的，先记录记录吧。

二、解决思路

关于这个问题，网上主要有两种解决思路。

第一种，也就是使用镜像的方式（✘）

pip install PackageName -i xxx --trusted-host xxx

这类型的解决办法我就没成功解决过这类问题（服务器端）！

第二种，用export重新设置一次http代理（✔）

下面是我之前用的

export http_proxy="http://xx.xx.xx.xx:xxxx"
export https_proxy="https://xx.xx.xx.xx:xxxx"

下面是我现在用的

export http_proxy="http://xx.xx.xx.xx:xxxx"
export https_proxy="http://xx.xx.xx.xx:xxxx"

注意看区别！
改了export后，问题成功被解决！文章来源地址https://www.toymoban.com/news/detail-838640.html
