这是我对此程序的代码。它工作正常，但突然无法工作，请任何人都可以解决此问题
model = Sequential()
print(nb_filters[0], 'filters')
print('input shape', img_rows, 'rows', img_cols, 'cols', patch_size, 'patchsize')
model.add(Convolution3D(
nb_filters[0],
kernel_dim1=1, # depth
kernel_dim2=nb_conv[0], # rows
kernel_dim3=nb_conv[1], # cols
input_shape=(1, img_rows, img_cols, patch_size),
activation='relu'
))
model.add(MaxPooling3D(pool_size=(1, nb_pool[0], nb_pool[0])))
model.add(Dropout(0.2))
model.add(Flatten())
model.add(Dense(128, init='normal', activation='relu'))
model.add(Dropout(0.2))
model.add(Dense(nb_classes,init='normal'))

最佳答案
根据Dr. Snoopy的建议，tf.keras.Model的参数为inputs和outputs，但是您分别在input中将其分别作为output和custom_model = Model(input=resnet_model.input, output=x)传递。
重现该错误的代码-
import numpy as np
import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import layers
X1 = tf.constant([2, 3, 4, 5, 6, 7])
X2 = tf.constant([2, 3, 4, 5, 6, 7])
yTrain = tf.constant([4, 6, 8, 10, 12, 14])
input1 = keras.Input(shape=(1,))
input2 = keras.Input(shape=(1,))
x = layers.concatenate([input1, input2])
x = layers.Dense(8, activation='relu')(x)
outputs = layers.Dense(2)(x)
mlp = keras.Model(input = [input1, input2], output = outputs)
mlp.summary()
mlp.compile(loss='mean_squared_error',
optimizer='adam', metrics=['accuracy'])
mlp.fit([X1, X2], yTrain, batch_size=1, epochs=10, validation_split=0.2,
shuffle=True)
mlp.evaluate([X1, X2], yTrain)

inputs和outputs。固定代码-
import numpy as np
import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import layers
X1 = tf.constant([2, 3, 4, 5, 6, 7])
X2 = tf.constant([2, 3, 4, 5, 6, 7])
yTrain = tf.constant([4, 6, 8, 10, 12, 14])
input1 = keras.Input(shape=(1,))
input2 = keras.Input(shape=(1,))
x = layers.concatenate([input1, input2])
x = layers.Dense(8, activation='relu')(x)
outputs = layers.Dense(2)(x)
mlp = keras.Model(inputs = [input1, input2], outputs = outputs)
mlp.summary()
mlp.compile(loss='mean_squared_error',
optimizer='adam', metrics=['accuracy'])
mlp.fit([X1, X2], yTrain, batch_size=1, epochs=10, validation_split=0.2,

mlp.evaluate([X1, X2], yTrain)
