Android 如何构建TensorFlow Lite并在Qt项目中使用？

我正在尝试启动项目：

 https://mechatronicsblog.com/tensorflow-lite-integration-with-qt-and-v-play-for-multi-platform-machine-learning-apps-on-ios-and-android/

但是有一个问题-Tensorflow子模块不正确

我通过以下命令从主repo下载了Tensorflow库：

git clone https://github.com/tensorflow/tensorflow.git

 bazel build --cxxopt='-D_GLIBCXX_USE_CXX11_ABI=0' -c opt --config=android_arm tensorflow/lite/java:libtensorflowlite_jni

然后我更新了依赖项：

tensorflow/lite/tools/make/download_dependencies.sh

然后，我通过以下命令构建了库：

git clone https://github.com/tensorflow/tensorflow.git

 bazel build --cxxopt='-D_GLIBCXX_USE_CXX11_ABI=0' -c opt --config=android_arm tensorflow/lite/java:libtensorflowlite_jni

以下是工作区的外观：

android_sdk_repository(
    name = "androidsdk",
    api_level = 21,
    build_tools_version = "26.0.2",
    path = "/home/user/Android/SDK",
)

android_ndk_repository(
    name = "androidndk",
    api_level = 20,
    path = "/home/user/android-ndk-r20b",
)

结果是成功的

然后我复制了library文件夹并将其粘贴到项目文件夹的根目录中。 我没有更改

.pro

然后，我在以下项目环境中构建了它：

Android NDK 20.1.5948944
Android SDK 26.1.1
Compiler Clang Qt 5.13.2 for Android ARMv7
JVM java-8-oracle

结果失败了

错误：

我想知道如何为Qt项目建立并包括Tensorflow库

编辑：

我编辑了
