[PYTHON/TENSORFLOW] add 함수 : 행렬 더하기

■ add 함수를 사용해 행렬을 더하는 방법을 보여준다.

▶ 예제 코드 (PY)


import numpy as np
import tensorflow as tf

ndarray1 = np.array([(1, 2, 3), (4, 5, 6), (7, 8, 9)], dtype = 'int32')
ndarray2 = np.array([(1, 0, 0), (0, 1, 0), (0, 0, 1)], dtype = 'int32')

tensor1 = tf.constant(ndarray1)
tensor2 = tf.constant(ndarray2)

tensor3 = tf.add(tensor1, tensor2)

with tf.Session() as sess:
    print(sess.run(tensor1))
    print(sess.run(tensor2))
    print(sess.run(tensor3))

[결과]

[[1 2 3]
 [4 5 6]
 [7 8 9]]
[[1 0 0]
 [0 1 0]
 [0 0 1]]
[[ 2  2  3]
 [ 4  6  6]
 [ 7  8 10]]
