本文介绍了如何在TensorFlow Lite中进行首次实践。首先，在依赖安装阶段，你需要安装Bazel，Android NDK（推荐版本14b），以及Android SDK和构建工具。在编译阶段，需要在TensorFlow根目录下配置configure文件，并使用Bazel进行编译。在编译过程中，可能遇到关于c++版本的问题，可以通过增加--cxxopt参数解决。如果遇到futex.h报错，可以参考相关博客文章添加宏定义来解决。

依赖安装阶段：

Install the latest version of Bazel as per the instructions on the Bazel website.
The Android NDK is required to build the native (C/C++) TensorFlow code. The current recommended version is 14b, which may be found here.
The Android SDK and build tools may be obtained here, or alternatively as part of Android Studio. Build tools API >= 23 is required to build the TF Android demo (though it will run on API >= 21 devices).

编译阶段：

./configure
注：tensorflow android 编译过程中，要首先在 tensorflow 根目录下配置 configure 文件，除了android ndk的配置选择Yes，其他配置项选择默认路径和No即可。
bazel build --cxxopt=’–std=c++11’ -c opt //tensorflow/examples/android:tensorflow_demo
注：增加 –cxxopt=’–std=c++11’ 参数，是因为mac 默认c++版本为11，因此增加
这里编译报错：

解决方法参考：https://blog.youkuaiyun.com/weixin_41480546/article/details/87533166
找到futex.h，增加宏定义：

vim ./platforms/android-14/arch-arm/usr/include/linux/futex.h

增加宏

#ifndef __user
#define __user
#endif
