C1_W1_Assignment error

[Maria_Petrovskaya]

Hello! My Assignment has 0% results, but all tasks are compleated
What should I do?

[TMosh]

The first step is to click on one of the ‘>’ markers. This will open a text window that will tell you what the grader is unhappy about.

Please post back a screen capture image of that message.

Hopefully a mentor for this course will be able to help you.

Hello! I try to repeat it many times, no progress…

[TMosh]

There are lots of threads in the forum about “grader feedback not found”.
I used the search tool and found this one:

Course 3 Week 1 Assignment - Grader Error: Grader feedback not found - Zero for all Exercises

For all exercises, I got this error: “Grader Error: Grader feedback not found Visit the Discussion forum to see if your peers are experiencing or have found resolutions for similar errors. If the error isn’t resolved in 24 hours, please reach out to Coursera through our Help Center.” I verified all of my functions, even I refreshed the environment, with new notebook did all my changes again. Still getting the same error.

@Maria_Petrovskaya did you find a solution for this error? I have the same problem.

I already contact the Coursera Help Center and they told me that they can’t change the grades. I don’t want them to change the grades, just be graded.

I know I don’t have syntax error, otherwise when I try to run the code it will give errors while running, and I got all the expected results.

I refresh the environment and reboot the notebook. Resubmit the assignment and anything worked. I keep getting the 0 grade. Any tips?

[TMosh]

Apparently your code is throwing an error when the grader runs it with the test cases the grader uses.

I’m not a mentor for that course, so I don’t know what its status is. Maybe there was an update to the grader, and your notebook is an older version that isn’t compatible.

Check on the notebook “Help” page and see when it was last updated.

[Guido_Carballo]

Nope, that wasn’t the error. I was using the latest version and the code was correct. Now I solved my issue and know what was the error and what not to do. The error was that I created an extra function so I wasn’t repeating code, and was calling that extra function from inside the function of the test. That function was outside the “### START CODE HERE ###” and “### END CODE HERE ###”.

[TMosh]

Thanks for the explanation.

It’s very important that you not add cells, or make any changes outside of the START CODE HERE blocks.

It’s a limitation of the grader.

[Maria_Petrovskaya]

Hello! Where can I see the original version of the notebook? I’m trying to find
incorrect changes that I may be, but without success.

[TMosh]

You will need to rename your current notebook, then use the Labs Help menu to get a fresh clean copy. Then you can compare the two.

Note that if you have modified the notebook, there can be invisible changes to the metadata, which are very difficult to inspect.
