Although I got “All tests passed” and the expected values are correct, the grader seems not to be able to run the code properly and I got “gradient_check_n_test: is not defined” at grading and a 80/100! Anyone faced the same issue?
Hey @zhaleh, could you share your entire grader output ? In the screenshot above, the left side of the message is telling useful information, without looking at which I am not able to help much here.
Thanks.
Hi, thanks for your reply. The grader output was embedded in the page. So the attached two screenshots should cover the full output.
Thanks,
Zhaleh
I was able to reproduce this error. Updating the notebook to the latest version should fix it. Could you confirm it, @zhaleh? Sorry for the inconvenience
