Resubmit programming assignment

Course Q&A Deep Learning Specialization Sequence Models

I am trying to resubmit Assignment 2 after fixing an issue but the system doesn’t take an updated assignment submission. Are you limited to only one submission per assignment or can you do multiple as in the quiz?

You can submit your notebook as many times as you like. There is no limit at all.

What specifically is the problem that makes you say “doesn’t take an updated assignment”?

Can you post a screen capture image of the grader’s detailed feedback?

Two things I see -

  1. The submission timestamp doesn’t change after resubmitting - tried twice
  2. Even though all functions execute successfully on the notebook, the result still shows partial (though passing score) and doesn’t correct the score or the summary on the function that used to fail but now passes

Not sure if it is because I already have a passing grade of 75/100.

It looks like there are two levels of problems:

  1. Your code is not fully correct, even if it passes the tests in the notebook.
  2. There is some problem on the grading servers with updating the scores.

Item 2) is the classic “bad weather in the Cloud” issue. We just have to wait and hope that the weather will clear up soon. Retry periodically.

For item 1), you need to look at your code for ways in which your code is not general: it passes one test case, but fails a different test case.

Thank you. I will retry for (1). For (2) I am not sure what to look for when it says “All tests passed”

Well, there are two separate mechanisms in the grader system I think:

The actual notebook grader, which gives you the feedback. And then it feeds the result (the latest score) into a queue for a different (probably single threaded) server that updates the actual course grades for everyone. At least that’s my theory based on observing the system. Sometimes it takes a long time for the second phase: it’s not unusual for that second phase to take up to 10 or 20 minutes. Of course there are different bad weather conditions in which the first phase doesn’t work either. :smile:

Understood @paulinpaloalto and thank you for that. The issue here is that the system doesn’t seem to accept the resubmission as the submission timestamp is not updated. So if that is not updated then I don’t expect the grades to change.

I guess the bad weather conditions have cleared up. The submission now just worked and the grades got corrected immediately.
