<p><a href=”https://www.geeksforgeeks.org/introduction-to-tensorflow/”>TensorFlow</a> is open-source Python library designed by Google to develop Machine Learning models and deep learning neural networks.
clip_by_norm() is used to clip tensor values to a maximum L2-norm.
Syntax: tensorflow.clip_by_norm(t, clip_norm, axes, name)
Parameters:
- t: It is the input tensor that need to be clipped.
- clip_norm: It is 0-D scalar tensor which defines the maximum clipping value.
- axes(optional): It’s 1-D vector tensor which defines the dimension to be used for calculating L2norm. If none is provided all dimensions will be used.
- name(optional): It defines the name for the operation.
Returns:
It returns a Tensor.
Example 1:
Python3
import tensorflow as tf
t = tf.constant([ 1 , 2 , 3 , 4 ], dtype = tf.float64)
clip_norm = . 8
print ( 't: ' , t)
print ( 'clip_norm: ' , clip_norm)
res = tf.clip_by_norm(t, clip_norm)
print ( 'Result: ' , res)
|
Output:
t: tf.Tensor([1. 2. 3. 4.], shape=(4, ), dtype=float64)
clip_norm: 0.8
Result: tf.Tensor([0.14605935 0.2921187 0.43817805 0.58423739], shape=(4, ), dtype=float64)
Example 2:
Python3
import tensorflow as tf
t = tf.constant([ 1 , 2 , 3 , 4 ], dtype = tf.float64)
clip_norm = 5.2
print ( 't: ' , t)
print ( 'clip_norm: ' , clip_norm)
res = tf.clip_by_norm(t, clip_norm)
print ( 'Result: ' , res)
|
Output:
t: tf.Tensor([1. 2. 3. 4.], shape=(4, ), dtype=float64)
clip_norm: 5.2
Result: tf.Tensor([0.94938577 1.89877153 2.8481573 3.79754307], shape=(4, ), dtype=float64)
