Tensorflow.js is an open-source library developed by Google for running machine learning models and deep learning neural networks in the browser or node environment.
The tf.cast() function is used to cast a specified Tensor to a new data type.
Syntax:
tf.cast (x, dtype)
Parameters: This function accepts two parameters which are illustrated below:
- x: The input tensor which is being casted.
- dtype: The data type in which input tensor is going to be casted.
Return Value: It returns a casted tensor of new data type.
Example 1:
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Initializing a tensor of some values const x = tf.tensor1d([2.3, 1.7, 5, 0, 1, 0.5]); // Calling the .cast() function over the // above tensor to cast in "int32" data type tf.cast(x, 'int32' ).print(); |
Output:
Tensor [2, 1, 5, 0, 1, 0]
Example 2:
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Using a tensor of some values // as the parameter for .cast() function to // cast into bool data type tf.cast(tf.tensor1d([0, 1, -3]), 'bool' ).print(); |
Output:
Tensor [false, true, true]
