Tensorflow.js tf.range() Function

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. range() is used to create a new tf.Tensor1D filled with the numbers in the range provided with the help of start, stop, step, and dtype.

Syntax:

tf.range(start, stop, step, dtype)

Parameters:

• start: It is an integer start value that denotes the starting number of the range.
• stop: It is an integer stop value that denotes the ending number of the range, and it is not included.
• step: It is an integer increment which is 1 or -1 by default. It is an optional parameter.
• dtype: It is the data type of the output tensor. It defaults to ‘float32’. It is an optional parameter.

Return Value: It returns a new Tensor1D object.

Example 1: In this example, we try to generate a range of numbers from 1 to 9 with default step 1.

Output:

Tensor
    [1, 2, 3, 4, 5, 6, 7, 8, 9]

Example 2: In this example, we try to generate odd numbers between 1 and 10 using step size 2.

Output:

Tensor
    [1, 3, 5, 7, 9]

Example 3: In this example, we try to generate even numbers between 0 and 10 using step size 2.

Output:

Tensor
    [0, 2, 4, 6, 8],

Example 4: In this example, we will try to use the dtype parameter.

Output:

​Tensor
    [true, false]
