首先在csdn上着了大神关于这个的实践如下链接
https://www.cnblogs.com/jojodru/p/7744630.html
但是报错如下，说是找不到opt选项。

由于对bazel不熟悉所以着了一篇介绍bazel的文章
https://blog.csdn.net/elaine_bao/article/details/78668657
此文介绍了bazel的基本工作原理，比较有用的一个命令是
bazel query --nohost_deps --noimplicit_deps 'deps(//main:hello-world)' \
--output graph
这个命令可以用来看编译的文件依赖图。
在编译lite的时候会编译python，这时候会导致一些错误如下：

可以通过修改编译目标来避免编译python
修改编译目标为 tensorflow:libtensorflow_framework.so
修改build_armv6.sh 增加-I编译选项。来避免下面的错误

这样就可以编译完成。
