我試圖保存 keras 完整模型，但遇到了這個錯誤Traceback (most recent call last):  File "d:/Workspace/College/Semester 8/Tugas Akhir/Keras-RFCN-master/Keras-RFCN-master/testing.py", line 133, in <module>    main()  File "d:/Workspace/College/Semester 8/Tugas Akhir/Keras-RFCN-master/Keras-RFCN-master/testing.py", line 96, in main    model.save("D:/weight.h5")  File "d:\Workspace\College\Semester 8\Tugas Akhir\Keras-RFCN-master\Keras-RFCN-master\KerasRFCN\Model\Model.py", line 560, in save    self.model.save(save_path)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\site-packages\keras\engine\network.py", line 1139, in save    save_model(self, filepath, overwrite, include_optimizer)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\site-packages\keras\engine\saving.py", line 415, in save_wrapper    save_function(obj, filepath, overwrite, *args, **kwargs)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\site-packages\keras\engine\saving.py", line 507, in save_model    _serialize_model(model, h5dict, include_optimizer)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\site-packages\keras\engine\saving.py", line 101, in _serialize_model    model_config = json.dumps(model_config, default=get_json_type)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\json\__init__.py", line 238, in dumps    **kw).encode(obj)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\json\encoder.py", line 199, in encode    chunks = self.iterencode(o, _one_shot=True)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\json\encoder.py", line 257, in iterencode    return _iterencode(o, 0)  File "C:\Users\kevin\anaconda3\envs\tf-gpu\lib\site-packages\keras\engine\saving.py", line 91, in get_json_type    raise TypeError('Not JSON Serializable: %s' % (obj,))TypeError: Not JSON Serializable: <KerasRFCN.Config.Config object at 0x0000029B0A3BD248>通過該錯誤，很明顯 JSON 無法序列化我的類，該類返回一個名為 config 的對象。那么如何確保 Keras 可以序列化我的配置..？？我認為在init中定義的所有定義都可以序列化。我真的是 python、Keras 和 TensorFlow 的新手。
