tensorflow中tensor与数组之间的转换

# 主要是两个方法：
# 1.数组转tensor:数组a,  tensor_a=tf.convert_to_tensor(a)
# 2.tensor转数组：tensor b, array_b=b.eval()

 1 import tensorflow as tf
 2 import numpy as np
 3 
 4 a=np.array([[1,2,3],[4,5,6],[7,8,9]])
 5 print (a)
 6 b=tf.constant(a)
 7 
 8 with tf.Session() as sess:
 9     print (b)
10     for x in b.eval():      #b.eval()就得到tensor的数组形式
11 print (x)
12 
13     print ('a是数组',a)
14 
15     tensor_a=tf.convert_to_tensor(a)
16     print ('现在转换为tensor了...',tensor_a)
