Cannot Access Jupyter Graded Assignment

Hi,

I’m having trouble accessing the graded lab assignment.

I wanted to restart the lab because I completed it a while ago and wanted to refresh my knowledge. However, after deleting the files, the lab no longer works.

I’ve tried logging out and back in, and I followed the steps outlined on Coursera’s support page, but nothing has resolved the issue.

I’ve also attached a screenshot of the problem for reference. Could someone please assist me in resolving this?

Thanks in advance!

Hi refer topic 1 a from the link below

It helped me retrieve a working version of the lab. However, it’s still not refreshed as new.
Many online threads talk about this method, but it didn’t help. The lab always retrieves an older version which is solved.

if you have deleted the assignment file from the file open section, and got 404 error, and rebooted, then the file you got is the latest version.

I don’t get what do mean by solved version??

You can also check if the file you are working is the latest version by checking on Update Log when you click on :question:

As Deepti says, that method should get you a “clean” copy of the latest version of the assignment. This is one of the first assignments in the course, so maybe you are just jumping to the conclusion that it’s completed because the template code contains a lot of code. Their style of writing the template fills in a lot of the code, but leaves the python token None in places where you need to fill in the critical parts of the algorithm. For example, here’s a portion of the clean code from one of the functions in that notebook:

    ### START CODE HERE ####
    
    # Iterate from bottom to top
    for row in reversed(range(num_rows)): 
        substitution_row = None

        # Get the index of the first non-zero element in the substitution row. Remember to pass the correct value to the argument augmented.
        index = None

If you don’t look too closely, that looks like “real” code, but it’s not a complete solution.

I just noticed the link you provided doesn’t take you to any link but Coursera general page.

Also avoid sharing any assignment link page on post thread. it is against community guidelines.

Now that

what do you mean by this?

Do you have access to the course still? Seems like you have completed the assignment and you wanted to refer again??

So in that case, you need to rename the submitted assignment ipynb file with submitted copy and then follow the step to get fresh copy.

Could share a screenshot of the page after you click File==>Open section, so we understand what is the issue.

I just tried loading that lab, and it got stuck at 90%.

So whatever is happening on this thread, I think there is a Coursera issue as well.

Update: Eventually the loading attempted timed-out, and I got a message that said:
“Let’s try preparing your lab again. Give it a few minutes and then hit refresh”
