源码编译安装tensorflow

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

root@3ddff7ac827a:/opt/tensorflow/tensorflow-r1.7# bazel build --config opt //tensorflow/tools/pip_package:build_pip_package

编译成功的显示
