Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length') for vertices of three.js

So I'm converting an html project to a laravel/vue project. The html file had a three.min.js file which I can not figure out the version of. And some custom script files.

I've imported all of them for my vue component. I ran into different errors for the three.min.js file, so I npm installed version r69 of three.js becauseI read in recent versions, the geometry had changed. One of the custom files, test.js is using three.js. And I am running into the following error in my console.log

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length') at test.js?t=1674045010699:37:39

test.js file code:

import * as THREE from "three";

// import ('../../assets/js/three.min.js')
// import "../js/anime.js"
// import "../js/three.js"

var canvas = document.querySelector("#scene");
var width = canvas.offsetWidth,
    height = canvas.offsetHeight;
var renderer = new THREE.WebGLRenderer({
    canvas: canvas,
    antialias: true,
});
renderer.setPixelRatio(window.devicePixelRatio > 1 ? 2 : 1);
renderer.setSize(width, height);
renderer.setClearColor(0x161d31);
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(100, width / height, 0.1, 10000);
camera.position.set(120, 0, 300);
var light = new THREE.HemisphereLight(0xffffff, 0x0c056d, 0.6);
scene.add(light);
var light = new THREE.DirectionalLight(0x590d82, 0.5);
light.position.set(100, 300, 400);
scene.add(light);
var light2 = light.clone();
light2.position.set(-100, 300, 400);
scene.add(light2);

var material = new THREE.MeshPhongMaterial({
    emissive: 0x23f660,
    emissiveIntensity: 0.4,
    shininess: 0,
});

var geometry = new THREE.IcosahedronGeometry(120, 4);

for (var i = 0; i < geometry.vertices.length; i++) {
    var vector = geometry.vertices[i];
    vector._o = vector.clone();
}

var shape = new THREE.Mesh(geometry, material);
scene.add(shape);

function updateVertices(a) {
    for (var i = 0; i < geometry.vertices.length; i++) {
        var vector = geometry.vertices[i];
        vector.copy(vector._o);
        var perlin = noise.simplex3(
            vector.x * 0.006 + a * 0.0002,
            vector.y * 0.006 + a * 0.0003,
            vector.z * 0.006
        );
        var ratio = perlin * 0.4 * (mouse.y + 0.3) + 0.9;
        vector.multiplyScalar(ratio);
    }
    geometry.verticesNeedUpdate = true;
}

function render(a) {
    requestAnimationFrame(render);
    updateVertices(a);
    renderer.render(scene, camera);
}

function onResize() {
    canvas.style.width = "";
    canvas.style.height = "";
    width = canvas.offsetWidth;
    height = canvas.offsetHeight;
    camera.aspect = width / height;
    camera.updateProjectionMatrix();
    renderer.setSize(width, height);
}

var mouse = new THREE.Vector2(0.8, 0.5);
function onMouseMove(e) {
    TweenMax.to(mouse, 0.8, {
        y: e.clientY / height,
        x: e.clientX / width,
        ease: Power1.easeOut,
    });
}

requestAnimationFrame(render);
window.addEventListener("mousemove", onMouseMove);
var resizeTm;
window.addEventListener("resize", function () {
    resizeTm = clearTimeout(resizeTm);
    resizeTm = setTimeout(onResize, 200);
});

I don't know anything about three.js, my main task here is to convert the entire project into vue/laravel so I have other things to worry about. Does anyone know how to resolve this?

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings

How to load Javascript with imported modules?

I am trying to import modules from tensorflowjs, and below is my code. test.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title </head> <body> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs@2.0.0/dist/tf.min.js"></script> <script type="module" src="./test.js"></script> </body> </html> test.js import * as tf from "./node_modules/@tensorflow/tfjs"; import {loadGraphModel} from "./node_modules/@tensorflow/tfjs-converter"; const MODEL_URL = './model.json'; const model = await loadGraphModel(MODEL_URL); const cat = document.getElementById('cat'); model.execute(tf.browser.fromPixels(cat)); Besides, I run the server using python -m http.server in my command prompt(Windows 10), and this is the error prompt in the console log of my browser: Failed to loa...
