为什么会出现“ AttributeError：'KerasClassifier'对象没有属性'__call__'？

Question

请有人说明为什么我的以下代码出现属性错误？

from sklearn.model_selection import cross_val_score
from keras.models import Sequential
from keras.layers import Dense 

def build_classifier():   #one of the parameter for KerasClassifier
    classifier = Sequential() #initialising ANN by defining sequence of layers
    classifier.add(Dense(units=6,activation='relu',kernel_initializer='uniform',input_dim=11))
    classifier.add(Dense(units=6,activation='relu',kernel_initializer='uniform'))
    classifier.add(Dense(units=1,activation='sigmoid',kernel_initializer='uniform'))
    #compiling the ANN
    classifier.compile(optimizer = 'adam',loss = 'binary_crossentropy',
                      metrics=['accuracy'])
    return classifier

#fitting model for k-fold cross validation
classifier = KerasClassifier(buil_fn = build_classifier,nb_epochs = 100,
                            batch_size=10)  ```

Answer 1

您有错字：buil_fn应该是build_fn

此外，nb_epochs应该是nb_epoch

#fitting model for k-fold cross validation classifier = KerasClassifier(build_fn = build_classifier,nb_epoch = 100, batch_size=10)
