首篇博客--记录pip换源和其它

# In case you need to modify your PIP configuration, please be aware that
# some configuration files may have a priority order. Here are the following 
# files that may exists in your machine by order of priority:
#
# [Priority 1] Site level configuration files
#       1. `/home/rzhang/miniconda3/envs/vast/pip.conf`
#
# [Priority 2] User level configuration files
#       1. `/home/rzhang/.config/pip/pip.conf`
#       2. `/home/rzhang/.pip/pip.conf`
#
# [Priority 3] Global level configuration files
#       1. `/etc/pip.conf`
#       2. `/etc/xdg/pip/pip.conf`

以上就是一般的conda虚拟环境下载源的优先级

因此可以修改~/.config/pip/pip.conf

[global]
index-url=https://pypi.douban.com/simple
#extra-index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host=
        pypi.douban.com
        pypi.tuna.tsinghua.edu.cn
timeout = 6000

另外可以修改~/.condarc如下所示，之前install keras的时候可以达到30m/s，但是不知道这种方式修改源下载速度变慢了
