Python – Tensorflow bitwise.right_shift() method

0 0 2 minutes read

Tensorflow bitwise.right_shift() method performs the right_shift operation on input a defined by input b and return the new constant. The operation is done on the representation of a and b.
This method belongs to bitwise module.

Syntax: tf.bitwise.right_shift( a, b, name=None)

Arguments

a: This must be a Tensor. It should be from the one of the following types: int8, int16, int32, int64, uint8, uint16, uint32, uint64.

b: This should also be a Tensor, Type same as a.

name: This is optional parameter and this is the name of the operation.

Return: It returns a Tensor having the same type as a and b.

Let’s see this concept with the help of few examples:
Example 1:

# Importing the Tensorflow library  
import tensorflow as tf  
  
# A constant a and b 
a = tf.constant(256, dtype = tf.int32) 
b = tf.constant(1, dtype = tf.int32)   
  
# Applying the right_shift() function  
# storing the result in 'c'  
c = tf.bitwise.right_shift(a, b)  
  
# Initiating a Tensorflow session  
with tf.Session() as sess: 
    print("Input 1", a) 
    print(sess.run(a)) 
    print("Input 2", b) 
    print(sess.run(b)) 
    print("Output: ", c) 
    print(sess.run(c)) 

Output:

Input 1 Tensor("Const_57:0", shape=(), dtype=int32)
256
Input 2 Tensor("Const_58:0", shape=(), dtype=int32)
1
Output:  Tensor("RightShift_3:0", shape=(), dtype=int32)
128

Example 2:

# Importing the Tensorflow library  
import tensorflow as tf  
  
# A constant a and b 
a = tf.constant([8, 16, 32], dtype = tf.int32) 
b = tf.constant([2, 2, 3], dtype = tf.int32)   
  
# Applying the right_shift() function  
# storing the result in 'c'  
c = tf.bitwise.right_shift(a, b)  
  
# Initiating a Tensorflow session  
with tf.Session() as sess: 
    print("Input 1", a) 
    print(sess.run(a)) 
    print("Input 2", b) 
    print(sess.run(b)) 
    print("Output: ", c) 
    print(sess.run(c)) 

Output:

Input 1 Tensor("Const_53:0", shape=(3, ), dtype=int32)
[ 8 16 32]
Input 2 Tensor("Const_54:0", shape=(3, ), dtype=int32)
[2 2 3]
Output:  Tensor("RightShift_1:0", shape=(3, ), dtype=int32)
[2 4 4]
