Hello Community Members,
I am experiencing this issue in my last graded assignment of the first module i.e Supervised ML Regression & Classification.
Hi @sanztechie ,
It looks like the notebook is not found. You can get a fresh copy by clicking the ‘?’ button at the top right corner. That will open up the option for getting a fresh copy of the notebook.
hello @kic ok let me try it. Thanks for the prompt response
now its working fine
Now when I am submitting my assignment for grading it will take half an hour approximately to process and got this. How can i fix it now ?
@sanztechie,
One thing that seems odd is that you’re getting the “NoneType” error on cell 14. For me, cell 14 is just a cell with some test code to test the implementation of compute_gradient:
Is it possible you added a cell with some test code and maybe that cell has a “None” in it? In any case, try choosing “Restart and Run All” from the Kernel menu and take a look at your cell 14 and see if you notice any suspicious “None” values in that cell.
If nothing looks wrong after trying this, the only other thought I have is that sometimes the grader can get mixed up if you submit a large project with lots of unnecessary data, so just to make sure everything is as clean as possible, try choosing “Restart and Clear Output” from the Kernel menu and then submit your assignment again.
The cell numbers are unique to the grader - they are not the same cell numbers as you find in your notebook.
If your notebook takes too long for grading, that’s a signal that you may have made some changes to your notebook that the grader does not enjoy.
For example, adding print() statements that output a lot of data for debugging, those will slow the grader down drastically.
That’s just one example.
thanks. I got your point. I tried it multiple times and issue is resolved
