The function of matrix stitching (tf.stack) and matrix decomposition function tf.unstack () example

Import TensorFlow as tf

a = Tf.constant ([1,2,3])
B = tf.constant ([4,5,6])

C = Tf.stack ([a,b],axis=0)
d = Tf.stack ([a,b],axis=1)

e = Tf.unstack (d,axis=0)
f = tf.unstack (D,axis=1) with


TF. Session () as Sess:
    print (' Raw vector data: ') print (
    Sess.run (a)) print (
    Sess.run (b)) print (     
    ' Matrix stitching function example, Get a matrix: ')  #返回值是多维矩阵
    print (' 0-D "stitching ')
    print (Sess.run (c))
    print (' in 1-d ' mode stitching ')
    Print (Sess.run (d))
    
    print (a ' matrix decomposition function example, get a list: ') #返回值是一个list   
    print (' 0-D ")
    print (Sess.run (e))
    Print (' 1 D "decomposition ')
    print (Sess.run (f))
