将 tensorflow lite 与 Qt 一起使用

Question

环境 ：

• 操作系统 ： Win10 64位
• Qt： 5.12.3
• 丹麦克朗： R18b
• JDK：jdk1.8.0_201

我想将tensorflow-lite与Qt5一起使用，但是当我尝试导入java类时，存在很多问题。但是我如何下载tensorflow-lite-gpu，tensorflow-lite-cpu和tensorflow-lite-support？

android 工作室在 build.gradle 中使用 3 行来完成这项工作，我也尝试将 3 行添加到 build.gradle 中。

dependencies {
// Build off of nightly TensorFlow Lite
implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly'
implementation 'org.tensorflow:tensorflow-lite-gpu:0.0.0-nightly'
implementation 'org.tensorflow:tensorflow-lite-support:0.0.0-nightly'    
}

错误消息

在帕斯特宾，因为它很长

我可以毫无问题地通过android工作室构建此示例，如何将tensorflow的java api与Qt一起使用？

Answer 1

答案很简单，只需要在build.gradle中添加几行(来自QtCreator，projects(alt+x(->other files->build.gradle(

1. 将以下行放在build.gradle的"android"块中

   compileOptions {
   sourceCompatibility = '1.8'
   targetCompatibility = '1.8'
   }
   aaptOptions {
   noCompress "tflite"
   }
   

2. 将 build.gradle 的依赖项块(不是构建脚本中的块(更改为

   dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
   // Build off of nightly TensorFlow Lite
   implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly'
   implementation 'org.tensorflow:tensorflow-lite-gpu:0.0.0-nightly'
   implementation 'org.tensorflow:tensorflow-lite-support:0.0.0-nightly' 
   }
   

这应该可以完成这项工作，完整的build.gradle看起来像

buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
}
}
repositories {
google()
jcenter()
}
apply plugin: 'com.android.application'
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
// Build off of nightly TensorFlow Lite
implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly'
implementation 'org.tensorflow:tensorflow-lite-gpu:0.0.0-nightly'
implementation 'org.tensorflow:tensorflow-lite-support:0.0.0-nightly'
// Use local TensorFlow library
// implementation 'org.tensorflow:tensorflow-lite-local:0.0.0'
}
