我在颤振中与tflite相处得很艰难
好吧，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];
});
}

我不知道是什么原因导致了这个错误，我也尝试过使用不同版本的tflite和不同类型的型号，并进行了清理，但问题仍然存在。感谢阅读，当做Roshan
删除pubspec.yaml中的资产它应该是：资产：
- fruit.txt
- 型号.tflite
- model_unquant.tflite
- labels2.txt
