最近重装了Ubuntu系统，更新到了Ubuntu 18.04，于是numpy也需要重新安装，但是一开始会出错，报错如下：

Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy

或许是因为国内连接外国的源的时候网络会出现错误，所以有必要使用国内的镜像源，推荐豆瓣的源，更换方法也很简单，只要在后面加上：

-i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

例如我在安装numpy的时候是：

pip3 install numpy

然后就会有上述错误，可以改成

pip3 install numpy -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

再例如在安装tensorflow的时候也会出现该错误：

A@A:~$ pip3 install tensorflow

  Could not find a version that satisfies the requirement tensorflow (from versions: )

可以改成：

pip3 install tensorflow -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

A@A:~$ pip3 install tensorflow -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
