2. Solutions
there are three methods: one is to switch the download source; Second, download the installation package of the corresponding platform and install it; Third, download the source code, compile and install
  The first method is to switch the download source recommendation

      http://pypi.douban.com/simple/

      Example: PIP install   Package name   — user -i   https://pypi.tuna.tsinghua.edu.cn/simple

      Permanent switch: under Linux, modify or create ~ /. PIP/pip.conf. The modification contents are as follows:

   [ global]

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

  Under windows, directly create a PIP directory in the user directory, such as C: \ users \ XX \ pip, and create a new file pip.ini, as follows:

  [ global]

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