Course 2, week 3. Ex 3.3 Train the Model

Staff please check it… were done before me in jupyter (pity a bit)

That is the way the assignment is designed. That function (model) is not one of the graded sections. Since they have not really explained that much about how gradients and training work in TF, rather than invest the effort in explaining all that, they ended up just giving you this as a “worked example”.

Ok, now it’s clear. Thank you

yeah I also clear now
