tensorflow.math.reduce\_any()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\_any()是用来计算张量的各维元素的 “逻辑或”。
语法:
tensorflow.math.reduce_any( input_tensor, axis, keepdims, name)
参数:
input\_tensor :它是要减少的布尔张量。[-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([True, False, False, True], dtype = tf.bool)
# Printing the input tensor
print('Input: ', a)
# Calculating result
res = tf.math.reduce_any(a)
# Printing the result
print('Result: ', res)
输出:
Input: tf.Tensor([ True False False True], shape=(4, ), dtype=bool)
Result: tf.Tensor(True, shape=(), dtype=bool)
示例 2:
# importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([[True, False], [False, True]], dtype = tf.bool)
# Printing the input tensor
print('Input: ', a)
# Calculating result
res = tf.math.reduce_any(a, axis = 1, keepdims = True)
# Printing the result
print('Result: ', res)
输出:
Input: tf.Tensor(
[[ True False]
[False True]], shape=(2, 2), dtype=bool)
Result: tf.Tensor(
[[ True]
[ True]], shape=(2, 1), dtype=bool)
