Error with Grading Exercise 3

Greetings community,

I,m getting a grading error in Exercise 3, that states the grading took a long time to complete. So it is telling me to make my solution more efficient, despite have a very simple NN, and getting a 99.8+% in the accuracy.

Does anyone know why this is happening?

Hello @obritosalas, welcome to the community!

Did you use convolutions to speed up the training?

I’m sorry but could you please delete the code from here, click my name and send me the whole notebook in a private message. I’ll run it on my end and see what’s wrong.
