ATTRIBUTERROR: объект «Tuple» не имеет атрибута «as_list» при использовании tf.keras.input ⇐ Python

[Гость]

Я пытаюсь использовать Resnet3d из библиотеки Tensorflow , но я получаю эту странную ошибку при попытке запустить блок

Код: Выделить всё

def create_model():
base_model = tfm.vision.backbones.ResNet3D(model_id = 50,
temporal_strides= [3,3,3,3],
temporal_kernel_sizes = [(5,5,5),(5,5,5,5),(5,5,5,5,5,5),(5,5,5)],
input_specs=tf.keras.layers.InputSpec(shape=(None, None, IMG_SIZE, IMG_SIZE, 3))
)

# Unfreeze the base model layers
base_model.trainable = True

# Create the model
inputs = Input(shape=[None, None, IMG_SIZE, IMG_SIZE, 3])
x = base_model(inputs) # B,1,7,7,2048
x = GlobalAveragePooling3D(data_format="channels_last", keepdims=False)(x)
x = Dense(1024, activation='relu')(x)
x = tf.keras.layers.Dropout(0.3)(x)  # Add dropout to prevent overfitting
outputs = Dense(NUM_CLASSES, activation='softmax')(x)

model = Model(inputs, outputs)

# Compile the model with class weights
optimizer = AdamW(learning_rate=1e-4, weight_decay=1e-5)
model.compile(
optimizer=optimizer,
loss='sparse_categorical_crossentropy',
metrics=['accuracy', tf.keras.metrics.AUC()]
)

return model

# Create and display model
model = create_model()
model.summary()
< /code>
Когда я запускаю это, я получаю ошибку ниже: < /p>

AttributeError: 'tuple' object has no attribute 'as_list'

Я попытался передать вход в аргумент Shape в качестве списка, но все же получил ту же ошибку.
