由于公司要在飞腾、龙芯上安装、因此源码编译tensorflow，但编译tensorflow要用bazel工具包来进行编译，因此要首先编译安装bazel。
因为tensorflow是基于python的一个模块，因此首先下载python等
下载 python-pip、enum、python-enum、python-numpy、python-dev、python-wheel、swig
直接下载升级，少走弯路
pip需要升级 pip install -U pip
缺少enum 会报错 apt-get install enum python-enum
编译需要联网，能访问github.com 、 bazel-mirror.storage.googleapis.com 否则解析不到，报错
