Submitted my Gradient Checking assignment-all code works and I got the right answer - I’m still getting an 80%-says it is failing in one cell and that the test might be hidden?
Sorry that the grader can’t give better feedback in this case. The tests for the 1D version of gradient checking in the notebook are pretty weak. They don’t even give you an “expected value”, so that’s one place to look. Here’s what the output should look like for gradient_check:
Your backward propagation works perfectly fine! difference = 2.919335883291695e-10
Is that what you see?
