Flutter Tflite PlatformException 错误模型尚未正确提及

Question

我在颤振中使用 tflite 时遇到了困难

问题是应用程序无法加载模型，但我确实在 pubspec.yaml 文件中提到了资产，而且我确实正确拼写了模型名称和标签文本，但我仍然收到错误

Pubspeck.yaml

assets:
  - asset/fruit.txt
  - asset/model.tflite
  - asset/model_unquant.tflite
  - asset/labels2.txt

加载模型

loadModel() async {
    String res = await Tflite.loadModel(
        labels: "asset/labels2.txt",
        model: "asset/model_unquant.tflite",
    );
    print(res);
  }

预测

predict(String path) async {
    var recognitions = await Tflite.runModelOnImage(
        path: path,
        threshold: 0.3,
        imageMean: 0.0,
        imageStd: 255.0,
        numResults: 292
    );
    setState(() {
      _recognitions = recognitions;
      char = _recognitions[0]["labels"];
      item = _recognitions[0];
    });
  }

我不知道是什么导致了这个错误，我也尝试过使用不同版本的 tflite 和不同类型的模型并进行清理，但问题仍然存在。 谢谢阅读， 问候， 肉山

Answer 1

删除 pubspec.yaml 中的资产 它应该是： 资产：

• 水果.txt
• model.tflite
• model_unquant.tflite
• labels2.txt
