Python - метод Tensorflow math.accumulate_n ()
Tensorflow math.accumulate_n() method performs performs the element-wise sum of a list of passed tensors. The result is a tensor after performing the operation. The operation is done on the representation of a and b. This method belongs to math module.
Syntax:
tf.math.accumulate_n( inputs, shape=None, tensor_dtype=None, name=None)Arguments
- inputs: This parameter takes a list of Tensor objects, and each of them with same shape and type.
- shape: This is optional parameter and it defines the expected shape of elements of inputs.
- dtype: This is optional parameter and it defines the expected data type of inputs.
- name: This is optional parameter and this is the name of the operation.
Return: It returns a Tensor having the same shape and type as the elements of inputs.
Example 1:
Выход:
Вход 1 Тензор ("Const_67: 0", shape = (2, 2), dtype = int32)
[[1 3]
[6 7]]
Вход 2 Тензор ("Const_68: 0", shape = (2, 2), dtype = int32)
[[5 2]
[3 8]]
Выход: Tensor ("AccumulateNV2_2: 0", shape = (2, 2), dtype = int32)

Example 2:
# Importing the Tensorflow library import tensorflow as tf # A constant a and ba = tf.constant([[2, 4], [1, 3]])b = tf.constant([[5, 3], [4, 6]]) # Applying the accumulate_n() function # storing the result in "c" c = tf.math.accumulate_n([b, a, b], shape =[2, 2], tensor_dtype = tf.int32) # Initiating a Tensorflow session with tf.Session() as sess: print("Input 1", a) print(sess.run(a)) print("Input 2", b) print(sess.run(b)) print("Output: ", c) print(sess.run(c)) |
Выход:
Вход 1 Тензор ("Const_73: 0", shape = (2, 2), dtype = int32)
[[2 4]
[1 3]]
Вход 2 Тензор ("Const_74: 0", shape = (2, 2), dtype = int32)
[[5 3]
[4 6]]
Выход: Tensor ("AccumulateNV2_5: 0", shape = (2, 2), dtype = int32)
