tensorflow中tensor與數組之間的轉換

# 主要是兩個方法：
# 1.數組轉tensor:數組a,  tensor_a=tf.convert_to_tensor(a)
# 2.tensor轉數組：tensor b, array_b=b.eval()

import tensorflow as tf
import numpy as np

a=np.array([[1,2,3],[4,5,6],[7,8,9]])
print (a)
b=tf.constant(a)

with tf.Session() as sess:
    print (b)
    for x in b.eval():      #b.eval()就得到tensor的數組形式
print (x)

    print ('a是數組',a)

    tensor_a=tf.convert_to_tensor(a)
    print ('現在轉換為tensor了...',tensor_a)
