Tensorflow.js tf.tile()函数
TensorFlow.js 是一个用于 JavaScript 机器学习的库。它帮助开发人员使用 JavaScript 开发 ML 模型,并直接在浏览器或 Node.js 中使用 ML。
tf.tile()函数用于通过重复 reps 给出的次数来创建张量。
句法:
tf.tile(x, reps)
注意:这个函数通过复制输入的次数来创建一个新的张量。例如,通过 [3] 平铺 [1, 2, 3, 4] 会产生 [1, 2, 3, 4,1, 2, 3, 4,1, 2, 3, 4]。
参数:该函数接受以下两个参数。
- x:传递给瓦片的张量。它可以是tf.Tensor 、 TypedArray 或 Array。
- reps:此参数定义每个维度的复制次数。
返回:返回tf.Tensor对象。
示例 1:
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Creating a tensor1d
const a = tf.tensor1d([1, 2, 3, 4]);
// Creating the tensor with the help of tile()
const x = a.tile([2]);
// Printing the tensor
x.print();
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Creating a tensor2d
const a = tf.tensor2d([1, 2, 3, 4, 5, 6],[2, 3]);
// Creating the tensor with the help of tile()
const x = a.tile([1,2]);
// Printing the tensor
x.print();
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Creating a tensor2d
const a = tf.tensor2d([1, 2, 3, 4, 5, 6],[2, 3]);
// Creating the tensor with the help of tile()
const x = a.tile([3,2]);
// Printing the tensor
x.print();
输出:
Tensor
[1, 2, 3, 4, 1, 2, 3, 4]
示例 2:
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Creating a tensor2d
const a = tf.tensor2d([1, 2, 3, 4, 5, 6],[2, 3]);
// Creating the tensor with the help of tile()
const x = a.tile([1,2]);
// Printing the tensor
x.print();
输出:
Tensor
[[1, 2, 3, 1, 2, 3],
[4, 5, 6, 4, 5, 6]]
示例 3:
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Creating a tensor2d
const a = tf.tensor2d([1, 2, 3, 4, 5, 6],[2, 3]);
// Creating the tensor with the help of tile()
const x = a.tile([3,2]);
// Printing the tensor
x.print();
输出:
Tensor
[[1, 2, 3, 1, 2, 3],
[4, 5, 6, 4, 5, 6],
[1, 2, 3, 1, 2, 3],
[4, 5, 6, 4, 5, 6],
[1, 2, 3, 1, 2, 3],
[4, 5, 6, 4, 5, 6]]
