Problems in week 2 of the course 2 in Specialization Deep Learningin of Coursera

I have problems with my grade in the course Improving Deep Neural Networks: Hyperparameter Tuning, Regularization and Optimization provided by Coursera.

I sent the file 4 times when I saw that it did not mark me as completed.

This is a Coursera Platform problem. Here’s a thread that gives instructions for how to get this resolved.
