keras.layers.concatenate 拼接

import numpy as np
import cv2
import keras.backend as K
import tensorflow as tf

a = K.variable(np.array([[1 , 2, 3]]))
b = K.variable(np.array([[3 , 2, 1]]))
c1 = K.concatenate([a , b] , axis=0)
c2 = K.concatenate([a , b] , axis=-1)

init = tf.global_variables_initializer()
with tf.Session() as sess:
    sess.run(init)
    print(sess.run(c1))
    print(sess.run(c2))

# [[1. 2. 3.]
#  [3. 2. 1.]]
# [[1. 2. 3. 3. 2. 1.]]
