所以最近根据这个,Tensorflow Lite现在支持
用于对象检测的mobilenet_ssd。太好了..
我设法用bazel构建并运行了这个演示,但最初我想用android studio来实现。可惜我做不到。
下面是我得到的错误:
Error:Plugin with id 'com.android.application' not found.
从评论中看,我并不是唯一一个对此感到困惑的人。有解决办法吗?或者目前没有gradle支持这个特定的更新?
任何能澄清这个问题的信息都是非常感谢的,因为我对人工智能世界还很陌生。

在android手机上运行示例应用程序(tfldetec)(search-tfldetec)
注意运行时是否抛出错误,例如;
Unknown failure (at android.os.Binder.execTransact(Binder.java:573))
Error while Installing APKs
...
Installation failed with message Invalid File: /.../app/build/intermediates/split-apk/debug/slices/slice_5.apk.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
然后尝试下列方法之一:
重新启动手机,然后重新运行应用程序
构建-重建项目,并重新运行应用程序

要使可选的对象跟踪工作,需要安装
libtensorflow_demo.so
;假设上面的tensorflow lite android示例和gradle(方法2)指令已经完成
执行上面的tensorflow lite android示例和bazel(方法1)说明-这将安装android示例的工作版本,其中
libtensorflow_demo.so
libtensorflow_demo.so
现在需要从安卓设备上安装的apk中提取打开android studio-视图-工具窗口-设备文件资源管理器
确保选择了Android设备
/data/app/org.tensorflow.lite.demo/lib/arm
-右键单击libtensorflow_demo.so
-另存为-保存到硬盘上的临时文件夹创建文件夹
tensorflow/contrib/lite/examples/android/app/src/main/jniLibs
创建4个子文件夹(
jniLibs/arm64-v8a
,jniLibs/armeabi-v7a
,jniLibs/x86
,jniLibs/x86_64
,libtensorflow_demo.so
)将

放入所有子文件夹在android studio中打开
git clone https://github.com/tensorflow/tensorflow
。使用Gradle重新构建
