在Windows 10环境下，使用TensorFlow 2.3.1和Python 3.6时，遇到模型保存时的KeyError问题。问题源于尝试格式化回调文件路径'./saved_models/model_batch{batch}.h5'失败。解决方案在于修正配置文件config.yml中相关路径设置。

Environment: Win10 + tensorflow2.3.1 + python3.6

    file_path = self.filepath.format(epoch=epoch + 1, **logs)
KeyError: 'batch'

During handling of the above exception, another exception occurred:
