Course 4, week 1, Convolution model step by step

good evening everyone,

i have finished all the required exercises in my assignment and when i tried running the code it displayed “all tests are passed” but i was graded 50/100 and i have not passed the assignment so any help?

Yes, this is a common problem. There are two levels of issues: the grader’s output is not helpful and the unit tests in the notebook do not “throw” if you forget to include the stride in conv_forward and pool_forward. That would be the first thing to check.

One way to check if this is the problem is to carefully examine your outputs in the pool_forward test case with stride = 2. All the values need to match the “expected values”, not just the first rows. But the test is not clever enough to “throw” if all the values don’t match.

thank you sir.
i’ll look it up and hopefully i’d fix the problem.
