My code is correct but my assignment has been failed!

My code gradient checking is correct but my assignment has been failed! Could anybody help me to check the issue please?

Please tell us which Specialization, Course and Assignment you are asking about. Note that you filed this under a completely general category on Discourse, so we can’t tell.

Deep Learning Specialization, Improving Deep Neural Networks: Hyperparameter Tuning, Regularization and Optimization Course, week1, Gradient Checking Assignment.

OK, I just moved the thread for you to the correct category by using the little “Edit Pencil” on the title.

Do you get any information from the grader? Please click “Show grader output” and “copy/paste” what you are seeing.

The problem with this exercise is that they don’t give you much feedback in the notebook about some of the sections. E.g. in the 1D gradient check section, they don’t tell you what the “Expected Output” is supposed to be. In Exercise 3, gradient_check, here is the output I get with correct code:

Your backward propagation works perfectly fine! difference = 2.919335883291695e-10

What do you see in that section?

I sent you an email with screenshots of my code. Could you please check it?

I see the same result!
