如何在Tensorflow.js中规范化日期？

const tf = require('@tensorflow/tfjs');
const moment = require('moment');

function normalizeDate(dateString) {
  const date = moment(dateString, 'YYYY-MM-DD');
  const year = date.year();
  const month = date.month();
  const day = date.date();
  
  // 将日期规范化为一个向量
  const normalizedDate = tf.tensor1d([year, month, day]);
  
  return normalizedDate;
}

const date = '2022-01-01';
const normalizedDate = normalizeDate(date);
console.log(normalizedDate);
