AttributeError: 'ModelCheckpoint' object has no attribute '_implements_train_batch_hooks'

I was using ModelCheckpoint from keras for model traing.Here is the code:

model1.compile(loss={'ctc': lambda y_true, y_pred: y_pred}, optimizer = 'adam')
 
filepath="model.hdf5"
checkpoint = ModelCheckpoint(filepath=filepath, monitor='val_loss', verbose=1, save_best_only=True, mode='auto')

# fitting model

model1.fit(x = [ IMAGES , LABELS_PADDED , IMAGES_LENGTH , LABELS_LENGTH ], y=np.zeros(len(IMAGES)) , batch_size = 256 , epochs = 1000 , validation_split = 0.33 , verbose = 1, callbacks = [ checkpoint ] )

And I encountered this error:

AttributeError                            Traceback (most recent call last)

How to resolve this?
