My Name is Nick and I am doing the course on “Introduction to Rag models” My problem is as follows… I am doing the course deeplearning.ai course Introduction to RAG Systems. I am struggling to submit the workbook for the first lab. I get graded at 0% even though the ‘unittest’ function indicates t…

Hi @NickRiches It could be your assignment has not be saved, and the grader is not picking up the latest version. Try to do a clean run , saved it before submitting to the grader. Kernel → restart and clear all output Cell → run all

Thanks. No that makes no difference. I still get zero points, even though the unittests are passed.

Check if your notebook has any ) or ] isolated on a line by itself. The grader copies the graded parts of your code into a different script, and the copy method doesn’t always work correctly in that case.

It does. But that shouldn’t make a difference. When my function generates a list containing dictionaries and produces this at the end of the cell, the square bracket is on the first line and the curly bracket is on the second line, e.g. [ {key: value}, {key: value}, {key: value} ] The desir…

The DL.AI support staff for this course seems to be temporarily unavailable. Also this is a new course and doesn’t have any active mentors yet. Just trying to help here - I’ve never seen this course material personally. But the issue you are reporting is also seen in other courses. The issue is li…

Thanks. I suspected this is what is happening. I could spend ages trying to tweak the output, e.g. pass it to a string and do some string processing, but even then, I doubt it would be exactly the format required. So I’m pretty stuck here. It’s a shame. The course materials are very good - a notch…

Hey @NickRiches , happy to jump in here to help you troubleshoot as I’m a current mentor for RAG (and was a tester as well). I just went through the M1 assignment notebook again on Coursera to see if I could replicate the issue you’re experiencing, but I was able to submit with the autograder succes…

Hi @NickRiches , Thanks for your message! This issue likely arises because the same type of quotation marks is being used for both the f-string delimiters and the dictionary keys. For example: f_string = f"This is an example, dictionary: {dict["key"]}" While the Jupyter environment is more flexibl…

Update: Now the grader feedback outputs the following message in this case There was a problem compiling your code. It looks like you used the same quotation marks for the f-string delimiter and for dictionary keys in Exercise 2. To fix this, use single quotes inside double quotes (e.g. f"{document…

Does anyone know how I can contact deeplearning.ai. I am perturbed that I am giving the right answer, but am unable to complete the exercise.
