Python | Tensorflow mutual flows method ()

The `tensorflow.math ` module provides support for many basic mathematical operations. The ` tf.reciprocal () ` [alias ` tf.math.reciprocal `] provides support for calculating the reciprocal input amount in Tensorflow. Expected to be input as complex numbers in the form , floating point numbers and integers. Input type — tensor, and if the input contains more than one element, the inverse element is calculated, ,

Syntax : tf.reciprocal (x, name = None) or tf.math.reciprocal (x, name = None)

Parameters :
x : A Tensor of type bfloat16, half, float32, float64, int32, int64, complex64 or complex128.
name (optional): The name for the operation.

Return type : A Tensor with the same size and type as that of x.

Code # 1:

 ` # Importing the Tensorflow library ` ` import ` ` tensorflow as tf `   ` # Constant vector of size 6 ` ` a ` ` = ` ` tf.constant ([` ` - ` ` 0.5 ` `, ` ` - ` ` 0.1 ` `, ` ` 0 ` `, ` ` 0.1 ` `, ` ` 0.5 ` `, ` ` 2 ` `], dtype ` ` = ` ` tf.float32) `   ` # Reverse function and ` ` # save result to & # 39; b & # 39; ` ` b ` ` = ` ` tf.reciprocal (a, name ` ` = ` ` ’reciprocal’ ` `) ` ` `  ` # Initiating a Tensorflow session ` ` with tf.Session () as sess: ` ` print ` ` (` ` ’Input type:’ ` `, a) ` ` print ` ` (` ` ’Input:’ ` `, sess.run (a)) ` ` print ` ` (` ` ’Return type:’ ` `, b) ` ` print ` ` (` ` ’Output : ’` `, sess.run (b)) `

Output :

` Input type: Tens or ("Const: 0", shape = (6,), dtype = float32) Input: [-0.5 -0.1 0. 0.1 0.5 2.] Return type: Tensor ("reciprocal: 0", shape = (6,) , dtype = float32) Output: [-2. -10. inf 10. 2. 0.5] `

denotes that inverse values ​​approach infinity when input approaching zero.

Code # 2: Rendering

 ` # Import Tensorflow library ` ` import ` ` tensorflow as tf `   ` # Importing the NumPy library ` ` import ` ` numpy as np ` ` `  ` # Import matplotlib.pylot ` ` import ` ` matplotlib.pyplot as plt ` ` `  ` # Two vectors sized 20 with values ​​from 0 to 10 ` ` a ` ` = ` ` np.linspace (` ` 0 ` `, ` ` 10 ` `, ` ` 20 ` `) ` ` `  ` # Apply inverse function and ` ` # save result to & # 39; b & # 39; ` ` b ` ` = ` ` tf. reciprocal (a, name ` ` = ` ` ’reciprocal’ ` `) `   ` # Initiating a Tensorflow session ` ` with tf.Session () as sess: ` ` ` ` print ` ` ( ’Input:’ , a) `` print ( ’Output:’ , sess.run (b))   plt.plot (a, sess .run (b), color = ’red’ , marker = ’o’ ) plt.title ( "tensorflow.reciprocal" )  plt.xlabel ( "X" )  plt.ylabel ( " Y " )  plt.grid ()   plt.show () `

Output:
