Input data and training process

[JiepingLLL]

I have run your program through your ipynb, but I can't find where is the data input? Are the nc and kpl files downloaded through gsutils? I would like to try out some other simple examples with your method. In addition, is the method of using machine learning in base/ml? I see that ml_model_inference_demo.ipynb uses ml, I hope to get your help, thank you very much.
