I passed all test and tried several times to submit the assignment, Every try, the grading process starts however I always get this message
hi @TheAli
can you post a complete screenshot of submission grader output which provides information on why you failed your submission inspite of passing all the unittest.
regards
Dr. Deepti
There is this message written for all exercises, Even though in the code I got âAll tests passedâ output for all tests
if you are confident of your codes being correct
Do clearing out cache and browsing history.
delete/clear out the kernel output.
reconnect the kernel
re-run each cell from beginning till end individually
save your work environment by clicking on 
now submit.
Let me know if you still encounter the same issue
Iâve tried this, I have even signed in from a totally different browser (Microsoft Edge) That I donât usually use and it still doesnât work!
Beside that Iâm sure of my code, I donât get any mark for any exercise!
All what I get is:
hi @TheAli
For exercise 4, although your codes are correct, for calculating the A2, chances are autograder is looking for use of np.matmul when you are implementing forward propagation instead of using @
Another major issue as @chris.favila mentioned in DM, for exercise 5 you failed 1 test, and the reason for that failed test is not random initialisation but your codes for logloss is incorrectly and cost incorrectly implementated.
Kindly use np.multiply and np.log to calculate the logloss and then use np.sum to calculate the cost.
Remember after you make any changes in codes, first clear out the kernel output, reconnect the kernel, re-run each cell individually till end. Save your work environment by clicking on save emi on and then submit.
Let us know if issue persists.

hii @TheAli
Your. exercise 5 code implementation is still incorrect. please avoid any hard code of implementation as autograder looks for codes the way it was given. You are suppose just replace the None placed between code markers ###START AND END CODE HERE### instead adding more code steps.
Please refer the image to do corrections to your incorrect codes
I am very bad in drawing, so apologies for my bad arrow markings 
Also donât forget the steps i mentioned earlier after you do the corrections. Good luck.

Dr. Deepti
The reason you are still failing the test is because of incorrect intialization of parameters which I noticed both in your previous notebook as well as updated notebook.
You were suppose to multiple the weight matrices with 0.01 for both W1 and W2.
Please compare your codes with this screenshot
Your codes screenshot i have sent in DM for your review as I cannot post grade function codes here due to community guidelines.

Hi @Deepti_Prasad @chris.favila
Problem isnât solved yet, does anyone from admins work on it?
@TheAli would you be able to send me via DM your solution notebook?
Hey @TheAli, thanks for sending me your solution. The issue is this part here:
The âparameters_2â variable has an indent that is preventing the grader to parse your notebook. The grader transforms your notebook into a script, this indent is breaking it. If you fix it, you should be able to get full grade.
Let me know if this works.
Cheers,
Lucas

Hi lucas,
Thank you for taking a look at the code and resolving the issue so quickly.
That said, I want to share some feedback about this experience. The issue had been ongoing for almost five days, and during that time I was repeatedly asked to make revisions, send screenshots, and apply changes that did not resolve the problem. In total, I spent several hours going back and forth trying to address those requests.
When the code was finally reviewed directly by a SPECIALIST, the issue was identified and solved in less than a minute. While I appreciate your help in resolving it, it is honestly frustrating to realize that so much time and effort could have been saved with an earlier direct review.
Because of this experience, I would like to report the issue with the review process so that similar situations can be avoided in the future. Could you please let me know if there is a way to contact customer support or submit feedback about this?
aah is that non-graded cell, i was checking the graded section only thinking learners is following assignment! guidelines.
Looks like no grader found feedback comes when the files is corruped or edited by learner . Good checkpoint to review from next time when the.grader throws such feedback
Thank you very much for resolving this issue.
Regards!
Dr. Deepti
I have informed @Community-Team about your concern, you can contact him whenever you need any customer support issues.
Keep Learning.

Hello @TheAli ,
Thank you for sharing this feedback. I completely understand your frustration; spending several hours over five days on an issue. And I apologize for the delay in getting you to that resolution.
I want to clarify that the mentor assisting you was following our standard diagnostic path to rule out common environment and configuration issues. Their work in gathering those screenshots and revisions actually helped narrow down the variables, which allowed the specialist to identify the root cause so rapidly once they stepped in.
That said, your point about the âescalation triggerâ is valid. We want to be as efficient as possible. You can submit formal feedback regarding the process here community@deeplearning.ai . We will use your experience to review how we can find a solution sooner.
