类型错误:添加的图层必须是类图层的实例.发现:<keras.engine.training.Model 对象在 0x7fa5bee17ac8>

问题描述

我正在尝试使用 keras 库的 Xception/Inception 模型训练模型，但我面临价值错误

I am try to train a model using Xception /Inception Model of keras library but I face value error

我从 kaggle 社区和笔记本中使用的数据集，我参考了 Notebook 但我尝试使用不同的模型，如 Xception/Inception 但类似的想法对我不起作用

Dataset which I use it from kaggle commuinity and Notebook which I refer Notebook But I am try to use different Model like Xception /Inception but silmilar idea not work for me

with strategy.scope():
    enet = keras.applications.inception_v3.InceptionV3(
        input_shape=(512, 512, 3),
        weights='imagenet',
        include_top=False
)

model = tf.keras.Sequential([
    enet,
    tf.keras.layers.GlobalAveragePooling2D(),
    tf.keras.layers.Dense(len(CLASSES), activation='softmax')
])

model.compile(
    optimizer=tf.keras.optimizers.Adam(lr=0.0001),
    loss = 'sparse_categorical_crossentropy',
    metrics=['sparse_categorical_accuracy']
)
 model.summary()

我面临的错误

推荐答案

您在 keras 和 tf.keras 库之间混合导入，它们不是同一个库并且不支持此组合.

You are mixing imports between keras and tf.keras libraries, they are not the same library and this combination is not supported.

您可以导入 tf.keras.applications 以访问 InceptionV3.

You can import tf.keras.applications to get access to InceptionV3.
