Tensorflow.js tf.TensorBuffer 类 .toTensor() 方法

Tensorflow.js是谷歌开发的一个开源库,用于在浏览器或节点环境中运行机器学习模型和深度学习神经网络。

tf.TensorBuffer 类 .toTensor()函数用于从指定的缓冲区及其值创建不可变的张量对象。

句法:

toTensor ()

参数:此函数不接受任何参数。

返回值:返回创建的不可变张量对象。

示例 1:

Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
  
// Creating a buffer of 2*2 dimensions
const buffer = tf.buffer([2, 2]); 
  
// Setting values at particular indices. 
buffer.set(5, 0, 0); 
buffer.set(10, 1, 0); 
  
// Converting the above buffer back
// to a tensor value to print with 
// the help of .toTensor() function
buffer.toTensor().print();


Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
  
// Creating a buffer of 3*3 dimensions
const buffer = tf.buffer([3, 3]); 
  
// Setting values at particular indices. 
buffer.set(5, 0, 0); 
buffer.set(10, 0, 1); 
buffer.set(15, 1, 0); 
buffer.set(20, 1, 1); 
buffer.set(25, 2, 0); 
buffer.set(30, 2, 1); 
buffer.set(35, 2, 2); 
  
// Converting the above buffer back 
// to a tensor value to print with
// the help of .toTensor() function
buffer.toTensor().print()


输出:

Tensor
  [[5 , 0],
   [10, 0]]

示例 2:

Javascript

// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
  
// Creating a buffer of 3*3 dimensions
const buffer = tf.buffer([3, 3]); 
  
// Setting values at particular indices. 
buffer.set(5, 0, 0); 
buffer.set(10, 0, 1); 
buffer.set(15, 1, 0); 
buffer.set(20, 1, 1); 
buffer.set(25, 2, 0); 
buffer.set(30, 2, 1); 
buffer.set(35, 2, 2); 
  
// Converting the above buffer back 
// to a tensor value to print with
// the help of .toTensor() function
buffer.toTensor().print()

输出:

Tensor
  [[5 , 10, 0 ],
   [15, 20, 0 ],
   [25, 30, 35]]
