Thanks for the answers Gus. Of course you helped me. I also follow you on Twitter and love your tweets. But I wonder why the test/train set split is weird, could you explain?
Thanks for the information,  I will try model maker but I’m wondering where I’m wrong.
I’m sorry the Colab link I shared didn’t save my latest work, so it showed sketchy work. I updated the link again, those who want to help can take a look.
