Python | Tensorflow sinh () method



The tensorflow.math module provides support for many basic mathematical operations. The tf.sinh () [alias tf.math.sinh ] function provides support for the hyperbolic sine function in Tensorflow. Input in radians is expected. Input type — tensor, and if the input contains more than one element, the element-wise hyperbolic sine is calculated.

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

Parameters :
x : A tensor of any of the following types: float16, float32, float64 , complex64, or complex128.
name (optional): The name for the operation.

Return type : A tensor with the same type as that of x.

Code # 1:

# Tensorflow library import

import tensorflow as tf

 
# Constant vector of size 6

a = tf .constant ([ 1.0 , - 0.5 , 3.4 , - 2.1 , 0.0 , - 6.5 ],

dtype = tf.float32)

 
# Usage sinh functions and
# save result to & # 39; b & # 39;

b = tf.sinh (a, name = `sinh` )  

 
# 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))

Exit:

Input type: Tensor ("Const_3: 0", shape = (6,), dtype = float32) Input: [1. -0.5 3.4 -2.1 0. -6.5] Return type: Tensor ("sinh: 0", shape = (6,), dtype = float32) Output: [1.1752012 -0.5210953 14.965365 -4.0218563 0. -332.57004]
