tensorflow.math.reduce\_euclidean\_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。
reduce\_euclidean\_norm()用于计算张量的各维元素的欧几里得准则。
语法:
tensorflow.math.reduce_euclidean_norm( input_tensor, axis, keepdims, name)
参数:
input\_tensor :它是要减少的数字张量。[-rank(input\_tensor), rank(input\_tensor)] 范围内。如果没有给这个值,所有的维度都会被减少。返回:
它返回一个张量。
示例 1:
# importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([1, 2, 3, 4], dtype = tf.float64)
# Printing the input tensor
print('Input: ', a)
# Calculating result
res = tf.math.reduce_euclidean_norm(a)
# Printing the result
print('Result: ', res)
输出:
Input: tf.Tensor([1. 2. 3. 4.], shape=(4, ), dtype=float64)
Result: tf.Tensor(5.477225575051661, shape=(), dtype=float64)
示例 2:
# importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([[1, 2], [3, 4]], dtype = tf.float64)
# Printing the input tensor
print('Input: ', a)
# Calculating result
res = tf.math.reduce_euclidean_norm(a, axis = 1, keepdims = True)
# Printing the result
print('Result: ', res)
输出:
Input: tf.Tensor(
[[1. 2.]
[3. 4.]], shape=(2, 2), dtype=float64)
Result: tf.Tensor(
[[2.23606798]
[5. ]], shape=(2, 1), dtype=float64)
