tensorflow Session()会话

Posted 2021-01-07 francischeng

session 是一个会话控制 

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)

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

# method 2
with tf.Session() as s:
    result = s.run(product)
    print(result)

第二种方法类似于文件的with，他会在结束时候关闭session
