W3 Programming assignment grading error

Hello there,
I’ve started the programming assignment several days ago and now I’ve finished it. I’ve submitted my assignment but it gives 0 pts. I’ve tried to run all of the notebook cells again and submitted, yet it gives 0 pts. Can someone help me for submitting my assignment please?

Thanks in advance.

Hi @TalhaOkur

Are all the unit tests passed without any error? Are there any error messages?

Hi @Kic

Some unit tests don’t work even though I wait for quite a while.

Hi @TalhaOkur ,

The unit tests are there to help you check if there is some error in of your code. They are not the full test, but it is essential that all the unit tests are passed before submitting the assignment.

Could you post a screen shot of those failing unit tests and the error trackbacks to help diagnose what the problem might be.

For some unit tests I’ve waited for 20 mins and there were no result. I’ve tried to run them again still * sign were there. Now that I’ve restarted the kernel and tried again running the tests, they started working. And I’ve submitted the assignment, still 0 pts. Here I am sharing all unit test-results:








Thank you for your interest.

Grading started working. Now, I need to fix some floating point issues I guess. Thank you @Kic !

Hi @TalhaOkur

Could check the correct reference to your lab. I couldn’t find the lab that you are referring under M4ML course2 week3.

Hi @Kic

I was referring to this one:

which course and which specialization? At the top of your notebook, you can copy the title from there.

It is C2_W3_Assignment of Calculus for Machine Learning and Data Science from Mathematics for Machine Learning and Data Science specialization.

hi, did you manage to fix your problem. I have the same issue and i’ve ben scratching my head for 2h now :(. thanks in advance

Hi @Kic

It’s the programming assignment under Week 3 Lesson 2 Neural Network with Two Layers

Hi @Helton_Kosturi

If the problem you’ve mentioned is “not working unit tests” then yes. I’ve restarted the kernel and run all cells in order again and it started working. For floating point issues, unfortunately I couldn’t find where I am doing wrong.

Hi, no I seem to have floating point issue as well. It marks partialy wrong

I’ve tried to use numpy as much as i can yet I’ve the problem and got 79pts. I think the problem for me is in cost function calculation. I will post here if I find any possible solution for the floating point issue.

To me seem the fwr propagation

Hi @TalhaOkur ,

It seems that my lab is different from yours. So I will leave this to other community members to help you with the problem.

I have the same problem, despite passing all the tests
