loadGraphModel модель json с локального устройства ERROR React Native

Question

Я использую модель loadGraphModel json с локального устройства ОШИБКА React Native Моя функция меня: КОД:

      async function predictModellocal1() {
        console.log("[+] Application started")
        const tfReady = await tf.ready();
        tf.device_util.isMobile = () => true
        tf.device_util.isBrowser = () => false
        console.log("[+] Loading  face detection model")
        const modelUrl =
              'https://storage.googleapis.com/tfjs-models/savedmodel/mobilenet_v2_1.0_224/model.json';
        console.log("[+] Loading  face detection model")
        const modelPath=
            'D:\\Code\\ReactNative\\appAI-mobilenet\\assets\\facenet\\weights_manifest.json';
        const modelPath1  = await require("./assets/facenet/weights_manifest.json");
        const model = await tf.loadGraphModel(modelPath1);
        console.log("[+] Loading model: done")
        const imgB64 = await FileSystem.readAsStringAsync(selectedImage.localUri, {
            encoding: FileSystem.EncodingType.Base64,
        });
        const imgBuffer = tf.util.encodeString(imgB64, 'base64').buffer;
        const raw = new Uint8Array(imgBuffer)
        const imageTensor = decodeJpeg(raw);
        const img = tf.image.resizeBilinear(imageTensor, [224,224])
        console.log(' Đã chạy')
        const img4d = img.reshape([1, 224, 224, 3,]);
        const prediction = await model.predict(img4d);
        const kq = getTopKClasses(prediction, 5)
        console.log(kq,'kq')
        setTextshow('ok')
    }

modelUrl работает хорошо. Я получаю модель из Google API.

      const modelUrl ='https://storage.googleapis.com/tfjs-models/savedmodel/mobilenet_v2_1.0_224/model.json';

Но я хочу загрузитьGrapModel с локального компьютера, чтобы использовать его в автономном режиме:

      const modelPath='D:\\Code\\ReactNative\\appAI-mobilenet\\assets\\facenet\\weights_manifest.json';
const modelPath1  = await require("./assets/facenet/weights_manifest.json");

Я использую Expo CLI для своего приложения. Спасибо всем

Удалить await ключевое слово при установке пути к modelPath1:

      const modelPath1 = require("./assets/facenet/weights_manifest.json");
const model = await tf.loadGraphModel(modelPath1);
