请问tensorflow出现这样的情况 是什么意思

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.
layer_config = serialize_layer_fn(layer)

请问tensorflow出现这样的情况 是什么意思

训练的时候 训练了50个batch会停止训练 请问是什么原因

Epoch 2/10
 50/150 [=========>....................] - ETA: 5s - loss: 0.0071C:\Users\Administrator\anaconda3\envs\Resnetmemory\lib\site-packages\keras\engine\functional.py:1410: 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.
  layer_config = serialize_layer_fn(layer)

从提示信息来看，是自定义layer有一个接口函数（get_config）没有实现（override ）
