问题记录

1. 更新python国内的源
   设为默认
   修改 ~/.pip/pip.conf (没有就创建一个)， 修改 index-url至tuna，例如

   [global]index-url = https://pypi.tuna.tsinghua.edu.cn/simple

2. pip升级失败
   pip install –upgrade pip
   Requirement already up-to-date: pip in /usr/local/lib/python2.7/dist-packages
   You are using pip version 8.1.1, however version 8.1.2 is available.
   You should consider upgrading via the ‘pip install –upgrade pip’ command

   解决办法：

   sudo apt-get remove python-pip

3. 不能更新scikit-learn
   使用pip show scikit-learn
   找到存放的位置
   Location: /usr/local/lib/python2.7/dist-packages
   若在/usr/lib/python2.7/dist-packages/则删除该文件夹即可
