解决pip install安装非常慢[Errno 101] 网络不可达问题
使用pip安装seaborn提示：
sudo python3.5 -m pip install seaborn
Collecting seaborn
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x7fb25d444fd0>: Failed to establish a new connection: [Errno 101] 网络不可达',)': /packages/a8/76/220ba4420459d9c4c9c9587c6ce607bf56c25b3d3d2de62056efe482dadc/seaborn-0.9.0-py3-none-any.whl
尝试加入default-time=100这个参数，提示：
sudo python3.5 -m pip --default-time=100 install seaborn
Collecting seaborn
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out. (read timeout=100.0)",)': /packages/a8/76/220ba4420459d9c4c9c9587c6ce607bf56c25b3d3d2de62056efe482dadc/seaborn-0.9.0-py3-none-any.whl
等了半天还是安装不了
在pip后面加入-i参数，比如：-i https://pypi.tuna.tsinghua.edu.cn/simple
sudo python3.5 -m pip --default-time=100 install seaborn -i https://pypi.tuna.tsinghua.edu.cn/simple
下载的飞快～
据说可以一劳永逸的方法，但我还没试过，过程如下：
mkdir ~/.pip
cd ~/.pip
touch pip.conf
gedit pip.conf
[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host = pypi.douban.com
cat pip.conf
