Not work local model load

[danekbiglike]

My code:

const axios = require('axios');
const tf = require('@tensorflow/tfjs-node');
const nsfwjs = require('nsfwjs');

// Загрузка модели из папки на вашем сервере
const url = "file://" + __dirname + "/nsfwjs/model.json";

async function classifyImage(imageUrl) {
    const pic = await axios.get(imageUrl, {
        responseType: 'arraybuffer',
    });

    const model = await nsfwjs.load(url, { size: 299 });

    // Преобразование изображения в формат tf.tensor3d
    const image = await tf.node.decodeImage(new Uint8Array(pic.data), 3);

    const predictions = await model.classify(image);

    image.dispose(); // Освобождение памяти

    return predictions;
}

My logs:

Even the example code doesn't work.

const axios = require('axios') //you can use any http client
const tf = require('@tensorflow/tfjs-node')
const nsfw = require('nsfwjs')
async function fn() {
    const pic = await axios.get('xxx.img', {
        responseType: 'arraybuffer',
    })
    const url = "file://" + __dirname + "/min_nsfwjs/model.json";
    const model = await nsfw.load(url, { size: 299 });
    // Image must be in tf.tensor3d format
    // you can convert image to tf.tensor3d with tf.node.decodeImage(Uint8Array,channels)
    const image = await tf.node.decodeImage(pic.data,3)
    const predictions = await model.classify(image)
    image.dispose() // Tensor memory must be managed explicitly (it is not sufficient to let a tf.Tensor go out of scope for its memory to be released).
    console.log(predictions)
}
fn()

@danekbiglike, can you help me to install thetensorflow/tfjs-node?
npm i tensorflow/tfjs-node couldn't find.

@hubsMIT1, it's npm i @tensorflow/tfjs-node
