Python – Tensorflow bitwise.invert() 方法

Tensorflow bitwise.invert()方法执行反转操作，结果将反转位，如 0 到 1 和 1 到 0。该操作是在 a 的表示上完成的。
该方法属于按位模块。

Syntax: tf.bitwise.invert( a, 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.
• name: This is optional parameter and this is the name of the operation.

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

让我们通过几个例子来看看这个概念：
示例 1：

import tensorflow as tf 
  
# A constant a 
a = tf.constant(6, dtype = tf.int32)  
  
# Applying the invert function 
# storing the result in 'c' 
c = tf.bitwise.invert(a) 
  
# Initiating a Tensorflow session 
with tf.Session() as sess:
    print("Input 1", a)
    print(sess.run(a))
    print("Output: ", c)
    print(sess.run(c))

输出：

Input 1 Tensor("Const_40:0", shape=(), dtype=int32)
6
Output:  Tensor("Invert_4:0", shape=(), dtype=int32)
-7

示例 2：

import tensorflow as tf 
  
# A constant a 
a = tf.constant([1, 4, 7], dtype = tf.int32)  
  
# Applying the invert function 
# storing the result in 'c' 
c = tf.bitwise.invert(a) 
  
# Initiating a Tensorflow session 
with tf.Session() as sess:
    print("Input 1", a)
    print(sess.run(a))
    print("Output: ", c)
    print(sess.run(c))

输出：

Input 1 Tensor("Const_39:0", shape=(3, ), dtype=int32)
[1 4 7]
Output:  Tensor("Invert_3:0", shape=(3, ), dtype=int32)
[-2 -5 -8]
