Team Software Engineering with AI - Programming Assignment: Solving Versioning and Dependency conflicts with an LLM

I have submitted both my assignments but keep getting an error message as follows:

Grader Error: Grader feedback not found

Please Help!

Generally this error message means that the grader is so unhappy with the format or content of your notebook, that it cannot even get started on grading it.

So on that assumption, first check if you made any changes to the notebook other than those discussed in the instructions.

In general, any of these (only a partial list) can cause the grader to get confused:

  • Adding new cells
  • Deleting existing cells
  • Moving cells within the notebook
  • Copying code or cells from one notebook to another.

Hi

I have tried to do it again, this time I used the backup file but I am still getting the same error.

Grader Error: Grader feedback not found

The only way I can have another go, if all the assignment files are reset again. I have tried using the ? and get latest version but nothing happens.

I think the whole course is still work in progress there are many issues to be resolved. I have completed the whole course and passed everything. If the files can’t be reset then the only alternative is to withdraw from the course. I should not have to stress about the Grader, surely I am not be tested on that!

“Get latest version” will only restore missing files. It will not overwrite your existing files.

So before you can “Get latest version”, you have to use the File Browser and delete (or rename) the existing .py files.

I’m having the same issue with Grader Error in the second exercise.

I see the output is similar to the data_example.csv file

Is there a way to understand what’s the issue? No error logs mean it is not easy to sort out by ourselves

What is the detailed feedback from the grader?
Please post a screen capture image.


Not a lot of information :slight_smile:

Have you perhaps change the name of the assignment file or maybe deleted parts of the notebook code? If yes then you need to perform the restore version as described above from Tom!

Other than that maybe coursera might have technical issues and you might need to try after some time again…

Generally that message means the structure of the notebook file (or the metadata within it) has been modified such that the grader cannot use it.

But this is not a notebook, this is the exercise “Programming Assignment: Solving Versioning and Dependency conflicts with an LLM” from week 3, where you run a bash command to package the files in a gz file and then submit things.

The csv file that is generated locally looks like the example one. Same for the json file. So I suspect this means the output is correct, so why this error? Or can we get a more detailed error message?

Also, this has been happening for over 24h now.

Ah, is this for “assignment part 2”?

I did not notice your post mentioned “in the second exercise”, since the rest of this thread has been about “assignment part 1”.

Well, the title of the thread is “Programming Assignment: Solving Versioning and Dependency conflicts with an LLM”, which corresponds to the title of the exercise in week 3 :slight_smile:

Neither part 1 nor part 2 use a notebook. But part 2 requires a gzip file that we generate with a bash script that is provided. But, yeah, I get that unhelpful error.

yeah, Coursera not helping either despite raising a request. Can’t wait days on grading errors. Cancelling the course, and claiming refund. Very disappointing experience.

For Part 1, the reference to “notebook” (i.e. ipynb files) in my reply applies equally to .py files. There was a recent update for Part 1 that fixed a number of issues.

I do not know if Part 2 has been recently updated. We’ve seen very few forum posts about Part 2.

Sorry I don’t have more definitive advice for this.

Hello,

Can you check you have all these files on the left hand (and still might be more there):


I just passed the grader.

There is a high possibility you have altered something, so the best advice now is to save you current work and then restore version as Tom advised!
