C4W4A2 : UNQ_C5 - Passes all tests but grader fails 80/100

Hi all,

Seems to be a common issue but none of the threads have helped me. All my tests pass but the grader gives me 80/100.

Below is the test output for UNQ_C5.

I believe I have corrected all I can think of. I have heavily reviewed UNQ_C1-5 and cannot for the life of me figure out what I am doing wrong. I won’t post the code until requested so as to follow the Honor Code.

Thanks,

Since train_step() is pretty simple, most errors are actually hiding in one of the other functions, but aren’t detected in their unit tests.

I found the problem. I had corrected an earlier issue and for some reason the submit tool didn’t register the update. I had used the Restart Kernel and Clear Output option several times as well as Save & Checkpoint but it apparently didn’t take. Note that it was also running and working with the updated version, just not submitting it. I had to completely exit/sign out of Coursera and log back in which reverted it back to the old version.

FYI the earlier error was that I was using tf.square functions rather than ** for scalar values.

paulinpaloalto submitted my code and it worked for him which gave me the idea to just try forcing it to clear.

Thanks,
Taylor

OK, thanks for the update.
