Session的两种使用方式

import tensorflow as tf

matrix1 = tf.constant([[3,3]])
matrix2 = tf.constant([[2,2]])

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

# session的两种打开模式

# method 1

# sess = tf.Session()
# result1 = sess.run(product)
# print(result1)
# sess.close()

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

运行的结果
