Error in grading practice exercises 2 week 2 - Course 1

[thanhnhan]

I got an error like this and don’t know how to solve it. Please help me.

I have edited my code. And now I have another problem. In addition, I changed the parameter of optimize() to the same as model() parameters of X_train, Y_train,

2000 and 0.5 but still got this error.

I fixed the error and got 100/100 already. Thanks
