WARNING: Retrying (Retry(total=4

人在日本，在Linux系统和win10使用Anaconda下载包的时候都出现了这个问题。由于实验室的有线网络确实用的代理，所以被认为不安全也是正常的。
完整报错信息：

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1091)'))': /pkgs/main/tensorflow/

方法1

参考https://blog.csdn.net/qq_34504481/article/details/81910253获得的解决方法是：

新建~/.pip
ls ~/.pip/pip.conf
vi ~/.pip/pip.conf
复制
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com
保存即可

方法2

pip install keras(或者你想安装的包) -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

douban是挺稳定的，基本的包都能下，境外慢一点，至少大部分情况下还能用（pytorch就不行了）

方法3(win10)
安装Proxifier，然后在这里面设置代理，就不会有这个问题
