Tensorflow.js tf.Tensor class .dispose() Method

  • Last Updated : 18 Aug, 2021

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

The .dispose() function is used to dispose the stated tf.Tensor from the memory.

Syntax:

dispose()

Parameters: This method does not hold any parameters.

Return Value: It returns void.

Example 1:

Javascript




// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
  
// Creating a tensor
const t = tf.tensor([6, 7]);
  
// Calling dispose() method
t.dispose();
  
// Printing output
console.log("Tensor Disposed.")

Output:

Tensor Disposed.

Example 2:

Javascript




// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
  
// Creating a 2d tensor
const tn = tf.tensor2d([6, 7], [1, 2]);
  
// Calling dispose() method
const y = tn.dispose();
  
// Printing output
console.log(tn)

Output:

An error occured on line: 11
Tensor is disposed.

Here, an error occurred while printing the tensor output as the tensor is already being disposed of.
