tensorflow NameError: name ‘layers‘ is not defined解决办法

错误代码：

 import tensorflow as tf
 net = layers.Dense(10)
 net.build((4, 10))
 net.kernel

NameError: name ‘layers’ is not defined

错误原因：tensorflow未加载layers
解决办法：

import tensorflow as tf
from tensorflow.keras import datasets, layers,optimizers
net = layers.Dense(10)
net.build((4, 10))
net.kernel

运行结果：
