如题，找了一个神经协调过滤的模型，但是想保存时提示自定义层什么什么的，搞不懂，没看到代码里面有什么自定义层啊
具体警告如下：
CustomMaskWarning: Custom mask layers require a config and must override get_config. When loading, the custom mask layer must be passed to the custom_objects argument. warnings.warn('Custom mask layers require a config and must override '
模型代码如下：
def get_compiled_neumf_model(num_users, num_items, lr = 0.001, mf_dim=10, layers_num=[10], reg_layers=[0], reg_mf=0):
assert len(layers_num) == len(reg_layers)
num_layer = len(layers_num) #Number of layers in the MLP
# Input variables
user_input = layers.Input(shape=(1,), dtype='int32', name='user_input')
item_input = layers.Input(shape=(1,), dtype='int32', name='item_input')
# Embedding layer
mf_embedding_user = layers.Embedding(input_dim=num_users, output_dim=mf_dim, name='mf_embedding_user',
embeddings_initializer=initializers.RandomNormal(),
embeddings_regularizer=regularizers.l2(reg_mf),

# MF part

mf_item_latent = layers.Flatten()(mf_embedding_item(item_input))
mf_vector = layers.multiply([mf_user_latent, mf_item_latent])
# MLP part

mlp_item_latent = layers.Flatten()(mlp_embedding_item(item_input))
mlp_vector = layers.concatenate([mlp_user_latent, mlp_item_latent])
for idx in range(1, num_layer):
layer = layers.Dense(layers_num[idx], kernel_regularizer=regularizers.l2(reg_layers[idx]), activation='relu', name="layer%d" % idx)
mlp_vector = layer(mlp_vector)
# Concatenate MF and MLP parts
predict_vector = layers.concatenate([mf_vector, mlp_vector])
# Final prediction layer

return model_nuemf
一个神经协同过滤的模型，henxiannan博士论文里的，原本代码是只保存权重，但是我想先试试能不能保存整个模型
