你愿意的话,可以使用我创建的一个,你可以在存储库中找到它。它位于这个应用程序
的文件夹中,我称之为

要加载模型,你首先需要告诉解释器在哪里可以找到它。该模型应该包含在你的应用程
序包中,因此你可以使用这样的代码来指定它:
let modelPath = Bundle.main.path(forResource: "flowers_model",
ofType: "tflite")
TensorFlow Lite 解释器是你之前安装的 pod 的一部分,你需要导入其库才能使用它:
import TensorFlowLite
然后,实例化一个解释器并让它加载你之前指定的模型,你可以使用如下代码:
var interpreter: Interpreter
do{
interpreter = try Interpreter(modelPath: modelPath!)
} catch _{
print("Error loading model!")
return
}
你现在已将解释器加载到内存中并准备就绪。所以接下来你需要做的就是提供一个它可
以为你解释的图像!

步:将图像转换为输入张量
这一步非常复杂,所以在深入研究代码之前,让我们直观地探索这些概念。回到图 11-1
你会注意到 iOS 可以将图像存储为 UIImage,这与被训练识别的模型的张量非常不同。
首先,让我们了解图像通常如何存储在内存中。
图像中的每个像素都由 32 位或 4
