How to get the model and log？

[velvetcake]

I benefited from your article.
So I have tried a lot of ways to get the model and log. But it does not work.
Could tell me how to get the model and log in Chain?
Thanks!

Hi guys, sorry for the late reply. The codes is pretty robust itself, you should get the same result if you just run the script.
