一，更換系統源：
首先備份系統源
sudo cp /etc/apt/sources-list /etc/apt/sources-list.bak
將sources-list更換成下面的源
清華大學源：
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial universe
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates universe
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security universe
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security multiverse
更新下源
sudo apt-get update
二，更換pip源
在用戶目錄下創建.pip文件夾，並創建pip.conf文件
