__init__() 收到意外的关键字参数“inputs”

class Model:
    def __init__(self):    
        self.model = Sequential()
        self.model.add(Conv2D(24, 3, 2, 'valid', input_shape=(75, 75, 3)))
        self.model.add(BatchNormalization())
        self.model.add(Conv2D(24, 3, 2))
        self.model.add(BatchNormalization())
        self.model.add(Conv2D(24, 3, 2))
        self.model.add(BatchNormalization())
        self.model.add(Conv2D(24, 3, 2))
        self.model.add(BatchNormalization())
        self.model.add(Flatten())

    def get_model(self):
        return self.model

class CNN_MLP:
    def __init__(self):
        model = Model()
        self.model = model.get_model()
        self.optimizer = optimizers

    def get_model(self): 
        self.model = self.extend(self.model)
        return self.model

    def extend(self, model):
        self.model = model
        self.sequence = Input(shape=(75, 75, 3), name='Sequence')
        self.features = Input(shape=(11, ), name='Features')
        conv_sequence = self.model(self.sequence)

         merged_features = concatenate([conv_sequence, self.features])
         fc1 = Dense(256, activation='relu')(merged_features)
         fc2 = Dense(256, activation='relu')(fc1)
         logits = Dense(10, activation='softmax')(fc2)

         # In the following statement I am getting the error
         self.model = Model(inputs=[self.sequence, self.features], outputs=[logits])
         return self.model

我正在尝试执行上述代码并收到上述错误。我是版本2.2.4-tf喀拉斯。我无法理解错误背后的原因。

谁能帮助我识别并解决问题？

谢谢你！

TypeError: __init__() got an unexpected keyword argument 'inputs'

您定义了一个名为Model，所以这会影响班级keras.models.Model，所以当你尝试实例化时Model，它使用您的类而不是 Keras 的类。

一个简单的解决方案是在调用中完全限定包名称：

self.model = keras.models.Model(inputs=[self.sequence, self.features], outputs=[logits])
