android - Flutter tflite 插件未在应用程序的发布版本中进行识别
问题描述
我一直在尝试在我的应用程序中使用颤振tflite 插件，到目前为止，我一直在开发/调试中对其进行测试，即当我运行以下命令时
var recognitions = await Tflite.runModelOnImage(
path: croppedFile.path, // required
imageMean: 0.0, // defaults to 117.0
imageStd: 255.0, // defaults to 1.0
numResults: 2, // defaults to 5
threshold: 0.2, // defaults to 0.1
asynch: true // defaults to true
);
它确实给了我一些认可。但是，当我制作相同代码的发布版本时，在具有相同输入数据的同一设备上运行时，它不会返回任何识别。我正在使用以下步骤制作发布版本：
//step 1
flutter build appbundle
// step 2
java -jar bundletool-all-1.3.0.jar build-apks --bundle=app-release.aab --output=app-release.apks --ks=key.jks --ks-pass= --ks-key-alias=key --key-pass=
// step 3
java -jar bundletool-all-1.3.0.jar install-apks --apks=app-release.apks
我还在我的 android build.gradle 中添加了以下内容
aaptOptions {
noCompress 'tflite'
noCompress 'lite'
}
如何在发布时获得不同的结果，而相同的代码在应用程序的调试版本中工作？我的设置中缺少什么？
注意：我只能在 Android 上测试
更新
进一步挖掘，我在配置文件模式下运行应用程序并发现以下日志（注意：这些仅在配置文件模式下显示，所以我不确定它与发布版本有多远。另外，在运行时我没有收到这些错误调试）：

由于我在调试模式下看不到行为，因此我仍然对运行发布版本时应用程序中发生的情况感到困惑。
