I have refreshed the page.
The feedback I’m getting is:
[ValidateApp | INFO] Validating ‘/home/jovyan/work/submitted/courseraLearner/W1A3/Gradient_Checking.ipynb’
[ValidateApp | INFO] Executing notebook with kernel: python3
Tests failed on 1 cell(s)! These tests could be hidden. Please check your submission.
I have restarted and rerun all cells.
Submitted four times.
What should I do in this case?
Just passing all the tests in the notebook is necessary but not sufficient to get 100% from the grader. The test cases don’t catch everything. E.g. in the 1D gradient_check case, there really isn’t a test: they commented it out. And they don’t really show you what the output should look like. Here’s what I get:
Your backward propagation works perfectly fine! difference = 2.919335883291695e-10
Of course that is only one possibility.
So what should I do? I’ve just tried copying all the code into a fresh notebook, but I keep getting the same grade 80%, and same feedback.
That means you have at least one bug in your code. Now you need to find it. You didn’t comment on whether your output matches in the 1D gradient_check case …
Sorry at first I didn’t understand what you meant.
Yes, I get the same message: Your backward propagation works perfectly fine! difference = 2.919335883291695e-10
Ok, thanks. So that’s not the issue. Please check your “DMs”.
