如何修复"tensorflow.keras.layers"没有属性"input"

Question

以下是我试图获得的字符串，但我不知道为什么我一直获得

tensorflow.keras.layers没有属性"input"，任何人都可以给出建议：(。

我不知道为什么，尽管我调出了数据，但它一直说没有keras的输入。

import tensorflow as tf
from tensorflow.keras import layers
from tensorflow.keras import datasets

mnist = datasets.mnist
(train_x, train_y), (test_x, test_y) = mnist.load_data()
inputs = layers.input((28, 28, 1))
net = layers.Conv2D(32, (3, 3), padding ='SAME')(inputs)
net = layers.Activation('relu')(net)
net = layers.Conv2D(32, (3, 3), padding ='SAME')(net)
net = layers.Activation('relu')(net)
net = layers.MaxPooling2D(pool_size=(2, 2))(net)
net = layers.Dropout(0, 25)(net)
net = layers.Conv2D(64, (3, 3), padding ='SAME')(net)
net = layers.Activation('relu')(net)
net = layers.Conv2D(64, (3, 3), padding ='SAME')(net)
net = layers.Activation('relu')(net)
net = layers.MaxPooling2D(pool_size=(2, 2))(net)
net = layers.Dropout(0, 25)(net)
net = layers.Flatten()(net)
net = layers.Dense(512)(net)
net = layers.Activation('relu')(net)
net = layers.Dropout(0, 5)(net)
net = layers.Dense(10)(net)
net = layers.Activation('softmax')(net)
model = tf.keras.Model(inputs=inputs, outputs=net, name='Basic_CNN')

Answer 1

必须使用Input而不是input
你所说的net = layers.Dropout(0, 25)(net)是什么意思
我想你指的是net = layers.Dropout(0.25)(net)。

Answer 2

试试这个：从tensorflow.keras.layers导入输入
