莫烦TensorFlow_02 Session的两种方法

import tensorflow as tf  

matrix1 = tf.constant([[3,3]]) # 1X2
matrix2 = tf.constant([[2],
               [2]])  

product = tf.matmul(matrix1, matrix2)  

#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)
