Hello,
I’m having an issue with the AI‑graded assignment. The grader keeps failing with 0/100 even though my code runs correctly in the notebook. I also do not have the “Switch to peer grading” option. Can a staff member please review or reset my assignment?
Thank you.
The first step would be to clarify which course you are taking and which assignment within that course is the one causing you this problem. The heading of your post is confusing because the title seems to be referring to DLS Course 2 Week 3, but then the course category you selected is “Agentic AI”. I’m familiar with DLS, but not familiar with the Agentic AI course. You also say this:
In DLS, the grading is not done by AI. I don’t know about the Agentic AI course but I would guess that the grading there is also not done by an AI model.
Hi! Sorry for the confusion. I am taking the DeepLearning.AI course:
Improving Deep Neural Networks: Hyperparameter Tuning, Regularization and Optimization (DLS Course 2).
I accidentally posted this under the Agentic AI category. The assignment that is failing is the Week 3 programming lab. The grader keeps giving 0/100 even though the notebook runs correctly.
Thank you for helping!
Thanks for clarifying. I will use the little “edit pencil” on the title to fix the course label.
If the notebook runs successfully, but fails the grader, that usually means you have “hard-coded” something such that it passes only one test case and fails a different test. But if you get 0 for everything, the error may be something more structural or a syntax error or the like.
Please expand the grader output by clicking “Show grader output” and then paste a screenshot of the output you are seeing from the grader. The first step is to see if it actually tells us anything that may be a clue. Sometimes you get lucky and get actionable feedback from the grader, but that is not a guarantee. 
We can’t really see anything from that other than the 0 scores. Notice the places where it says “Show grader output” and those are blue? That means those are links. Please click on one of them and then show us what you see by doing that.
Is there more information below the point at which it says “The error was:”? It might be useful to see that, if so …
Also I just noticed that you are apparently getting 0 points on everything. I had not previously noticed that you showed at least 3 different assignments with 0 points:
Regularization (W1 A2)
Gradient checking (W1 A3)
TensorFlow Introduction (W3 A1)
So there must be something consistent that you are doing incorrectly. Did you perhaps copy notebooks from a different version of the course?
Thank you for your detailed reply.
Below the line that says “The error was:” there is no additional message shown in the grader output. It just ends there, so I don’t see any more specific error text.
Regarding the 0 points on multiple assignments: I did not copy notebooks from a different version of the course. I am using the notebooks provided directly in this current session of the course, and I have been editing and submitting only those.
Since I’m getting 0 on Regularization (W1 A2), Gradient Checking (W1 A3), and TensorFlow Introduction (W3 A1), it sounds like there might be some structural issue I’m consistently doing wrong (for example, how I’m running or submitting the notebook). Could you please suggest what common mistakes might cause 0 on all these labs, even when the code runs?
Thank you again for helping me troubleshoot this.
You are taking this on the DeepLearning.AI Learning Platform. I’ve only used that a little bit, compared to Coursera, but one thing to check is that you’ve actually “Saved” your latest version of the code before you hit “Submit” to the grader. At least on Coursera it was not safe to assume that hitting “Submit” would save. Meaning that without the Save, you can’t be sure that the grader is actually grading the same version that you are running.
One way to check whether things are really being saved or not would be to do a browser “Refresh” on one of the tabs that has a notebook open. If you do that and then page through the notebook, are all your changes still there?
It would also be worth checking all the three failing assignments and clicking the “Show Grader Output” links in the hopes that at least one of them will show more details. I really really wanted to see the next line that actually showed the error message. 
Thank you for the suggestion. I will try refreshing the notebook tabs to confirm whether my changes are actually being saved before submission. I’ll also check all three failing assignments again and click the “Show Grader Output” links to see if any of them show more details.
I’ll report back with what I find.
Hi, I don’t have much time left before the deadline. Every submission still shows “Filename: nbgrader-part” and gives 0/100, even after saving, refreshing, and resubmitting. It looks like the platform is not submitting my actual notebook at all.
Can you please reset this assignment or force the grader to use the correct file? I cannot fix this from my side.
Hi, I need urgent help. I must finish this course today. Every submission shows “Filename: nbgrader-part” and gives 0/100, even after saving, refreshing, and resubmitting. The grader is not receiving my actual notebook.
Please reset or repair this assignment so the correct file is submitted. I cannot fix this from my side and I am running out of time.
I submitted those assignments successfully last week FWIW. The mentors are just fellow students, so we can’t access or reset anyone’s assignments. I will check with the course staff and see if they have any tools to address this issue.
One other thing to note is that the deadlines are fake in the sense that they just reset if you miss them.
Did you take DLS Course 1 before this one? Did the assignments there submit successfully? If so, then has anything changed in your IT environment? E.g. are you connecting from a different network or using a different computer or browser? Maybe this is an IT issue on your side.
Yes, I completed DLS Course 1 and all the assignments submitted successfully. Nothing has changed in my setup — same computer, same browser, same network. The issue seems specific to this assignment because the grader keeps showing “Filename: nbgrader-part” instead of my actual notebook. It looks like the platform isn’t picking up the correct file.
Thanks, Paul.
@KARUNA_MANI, I have sent you a direct message regarding this.
Hi Paul. The screenshots show Coursera and not the LP. Edited the topic tags as such.
