Tensorflow tf.sub() Function

The tf.sub() function returns the subtraction of two tf.Tensor objects element wise. The tf.Tensor object represents the multidimensional array of numbers.

Syntax:

tf.sub( a, b )

Parameters:

• a: It contains the first tf.Tensor object. The value of this parameter can be tf.TensorTypedArray|Array.
• b: It contains the second tf.Tensor object that subtract from first tf.Tensor object. The value of this parameter can be (tf.Tensor|TypedArray|Array). The type of this parameter is same as type of a.

Return Value: This function returns the tf.Tensor object.

Example 1:

Output:

Tensor
 [5, 10, 15, 20, 25]

Example 2:

Output:

An error occurred on line: 7
Operands could not be broadcast together with shapes 3 and 5.

Example 3:

Output: 

Tensor
 [-15, -20, -5, -10, 5]
