Invert

public final class Invert

Invert (flip) each bit of supported types; for example, type `uint8` value 01010101 becomes 10101010.

Flip each bit of supported types. For example, type `int8` (decimal 2) binary 00000010 becomes (decimal -3) binary 11111101. This operation is performed on each element of the tensor argument `x`.

Example: 

import tensorflow as tf
 from tensorflow.python.ops import bitwise_ops
 
 # flip 2 (00000010) to -3 (11111101)
 tf.assert_equal(-3, bitwise_ops.invert(2))

               dtypes.uint8, dtypes.uint16, dtypes.uint32, dtypes.uint64]
 
 inputs = [0, 5, 3, 14]
 for dtype in dtype_list:
   # Because of issues with negative numbers, let's test this indirectly.
   # 1. invert(a) and a = 0
   # 2. invert(a) or a = invert(0)
   input_tensor = tf.constant([0, 5, 3, 14], dtype=dtype)
   not_a_and_a, not_a_or_a, not_0 = [bitwise_ops.bitwise_and(
                                       input_tensor, bitwise_ops.invert(input_tensor)),
                                     bitwise_ops.bitwise_or(
                                       input_tensor, bitwise_ops.invert(input_tensor)),
                                     bitwise_ops.invert(
                                       tf.constant(0, dtype=dtype))]
 
   expected = tf.constant([0, 0, 0, 0], dtype=tf.float32)
   tf.assert_equal(tf.cast(not_a_and_a, tf.float32), expected)
 
   expected = tf.cast([not_0] * 4, tf.float32)
   tf.assert_equal(tf.cast(not_a_or_a, tf.float32), expected)
 
   # For unsigned dtypes let's also check the result directly.
   if dtype.is_unsigned:
     inverted = bitwise_ops.invert(input_tensor)

Inherited Methods

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "Invert"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static Invert<T> create (Scope scope, Operand<T> x)

Factory method to create a class wrapping a new Invert operation.

Parameters
scope current scope
Returns
  • a new instance of Invert

public Output<T> y ()
