## sess Session 会话控制的简单运用
## sess 每run一次，便执行一次结构
## sess.close() 
import tensorflow as tf

matrix1 = tf.constant([[3,3]])  # 1*3 矩阵
matrix2 = tf.constant([[2],
                       [2]])  # 2*1 矩阵

product = tf.matmul(matrix1,matrix2)  # matrix multiply np.dot(m1,m2)

### method 1 
sess = tf.Session()
result = sess.run(product)
print(result)
sess.close()

### method 2
with tf.Session() as sess:
    result2 = sess.run(product)
    print(result2)
# 已经自动close
