Tensorflow.js tf.util.sizeFromShape() Function

Tensorflow.js is an open-source library that is being develop by Google for running machine learning models as well as deep learning neural networks in the browser or node environment.

The .util.sizeFromShape() function is used to find the number of elements i.e. the size of the stated tensor input from the stated shape.

Syntax :  

tf.util.sizeFromShape(shape)

Parameters:  

• shape: It is the stated shape whose size is to be returned. It is of type number[].

Return Value: It returns a number.

Example 1:

Javascript

// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"

// Defining shape
const sh = [5, 8, 1];

// Calling tf.util.sizeFromShape() method
const num = tf.util.sizeFromShape(sh);

// printing output
console.log(num);

Output:

40

Example 2:

Javascript

// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"

// Calling tf.util.sizeFromShape() method and
// printing output
console.log(tf.util.sizeFromShape([1.4, 5.6, 9.0]));

Output:

70.55999999999999
