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()

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的数组形式
print (x)

    print ('a是数组',a)

    tensor_a=tf.convert_to_tensor(a)
    print ('现在转换为tensor了...',tensor_a)
