我无法导入'package:tflite_flutter/tflite_flutter.dart';

Question

我创建了一个深度学习模型（使用 Inception），然后将该模型转换为 TensorFlow lite 模型以在 Flutter 中使用。后来我把这个模型添加到了Flutter的assets文件夹中。

但是我无法访问 tflite_flutter 包的内容。所以我无法导入

package:tflite_flutter/tflite_flutter.dart';

这是我的

main.dart

文件：

import 'package:flutter/material.dart';
import 'package:kamera/pages/home_page.dart';
import 'package:tflite_flutter/tflite_flutter.dart'; 

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await loadModel();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Mobil Uygulama',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
    );
  }
}

Future<void> loadModel() async {
  await TfliteFlutter.loadModel(
    model: 'assets/inceptionv3_model.tflite',
    // labels: 'assets/inceptionv3_labels.txt', 
  );
}

这是我的

pubspec.yml

文件：

dependencies:
  flutter:
    sdk: flutter
  image_picker: ^1.1.1
  tflite_flutter: ^0.10.4
flutter:
  assets:
    - assets/inceptionv3_model.tflite

这是错误：

    },

Answer 1

flutter 中有两个独立的张量流主包。

1. tflite_flutter
2. flutter_tflite

我可以看到您已导入第一个包，但使用了第二个包的模型加载模式。 您需要使用以下行来加载带有导入包的模型；

final interpreter = await Interpreter.fromAsset('assets/your_model.tflite');

然后您可以使用

interpreter

来推断您的模型。
