tensorflow.clip\_by\_norm()TensorFlow是谷歌设计的开源Python库,用于开发机器学习模型和深度学习神经网络。
clip\_by\_norm()用于将张量值剪辑成最大的L2-norm。
语法:
tensorflow.clip_by_norm(t, clip_norm, axes, name)
参数:
clip\_norm :它是0-D标量张量,定义了最大剪裁值。返回值:
它返回一个张量。
示例 1:
# Importing the library
import tensorflow as tf
# Initializing the input tensor
t = tf.constant([1, 2, 3, 4], dtype = tf.float64)
clip_norm = .8
# Printing the input tensor
print('t: ', t)
print('clip_norm: ', clip_norm)
# Calculating tangent
res = tf.clip_by_norm(t, clip_norm)
# Printing the result
print('Result: ', res)
输出:
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)
示例 2:
# Importing the library
import tensorflow as tf
# Initializing the input tensor
t = tf.constant([1, 2, 3, 4], dtype = tf.float64)
clip_norm = 5.2
# Printing the input tensor
print('t: ', t)
print('clip_norm: ', clip_norm)
# Calculating tangent
res = tf.clip_by_norm(t, clip_norm)
# Printing the result
print('Result: ', res)
输出:
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)
