numpy、pandas下载速度慢问题

numpy、pandas下载速度慢问题:
一般直接python下安装可能出现速度较慢以及连接超时情况:
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError
解决办法:pip后加入镜像地址进行下载
ip install selectivesearch -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
#安装pandas
pip install pandas -i “https://pypi.doubanio.com/simple/”
#安装numpy
pip install numpy-i “https://pypi.doubanio.com/simple/”
