Week 3 -> machine translation print(summary(model)) error

[Oskar_DH]

Hi. good evening.
I´m trying to solve the exercise 2 modelf; i code the needed lines; but at the time to grade the part… appear that I have an error printing the model… appear the next messages

I don’t know if I have to change part of my code (maybe a input of some layer could be the origin of the error), or if is a problem with the grade code… cause I didn’t have any problem with the first step.

(state actualization)
I decide to run the sumary(modelf) cell.
The result show that the concatenate layer doesn’t have a defined size.
My doubt is, how I can solve this.

Hello,

I had the same issue and simply solved it by restarting the kernel.

Your implementation is right.
