pip安装sentence transformer失败原因解析

本来是很简单的一个命令解决的事情

pip install sentence-transformers

结果报错

WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7ff139858250>: Failed to establish a new connection: [Errno -3] ????????')': /simple/sentence-transformers/
ERROR: Could not find a version that satisfies the requirement sentence-transformers (from versions: none)
ERROR: No matching distribution found for sentence-transformers

之后尝试加镜像：

pip install sentence-transformers -i / --trusted-host pypi.douban

还是无法安装，关闭代理仍然未果……有说把pip的版本降到20.2，然而就在我卸载pip之后打算安装对应版本时，

apt-get install pip

报错如下：

最后走投无路，决定求助实验室网管，真相却是：

前天机房网线不够，有两台机器把外网的网线拔了用到其他地方了，网线没接……

概率极低的原因……

服务器要联网啊伙伴们！！！
