python - `TypeError: get_config() missing 1 required positional argument: ' self '` 尝试在 Tensorflow 中保存模型时

Question

请帮我解决以下问题。我似乎无法保存我的模型。如您所见，我确实引用了 Sequential() 方法的实例

model = tf.keras.models.Sequential()
model.add(tf.keras.layers.InputLayer(input_shape=[timePortion,1 ]))
model.add(tf.keras.layers.Conv1D(kernel_size=timePortion,
                                 filters=1000, 
                                 strides=1,
                                 use_bias=False,
                                 activation="relu",
                                 kernel_initializer=tf.keras.initializers.VarianceScaling))
model.summary()
model.add(tf.keras.layers.Dropout(rate=0.2))
model.add(tf.keras.layers.Flatten())
model.add(tf.keras.layers.Dense(32,
                                activation='relu', 
                                kernel_initializer=tf.keras.initializers.VarianceScaling))
model.add(tf.keras.layers.Dense(8,
                                activation='relu', 
                                kernel_initializer=tf.keras.initializers.VarianceScaling))
model.add(tf.keras.layers.Dense(1, 
                                kernel_initializer=tf.keras.initializers.VarianceScaling))
model.summary()
model.compile(optimizer=tf.keras.optimizers.Adam(lr=0.001),
              loss="mean_squared_error", 
              metrics=["accuracy","mae"])
filepath = "model.h5"
model.fit(inputs,
          labels,
          steps_per_epoch=1,
          epochs=2,
          shuffle=False, 
          verbose=1)
tf.keras.models.save_model(model,
                           filepath, 
                           overwrite=True,
                           include_optimizer=True)

我在将模型保存在 Jupyter 笔记本中时遇到问题。该文件实际上已创建，但随后出现此错误。这很奇怪，因为我正在引用模型实例。

TypeError: get_config() missing 1 required positional argument: 'self'

问题在于无法序列化的内核初始化程序，因为您尚未实例化它。要实例化它，请添加圆括号 ():

kernel_initializer=tf.keras.initializers.VarianceScaling()
