I suggest you study this post to get clues on how to proceed:

Week 4 assignment deep neural network application

That error means that the costs array returned by your two_layer_model function must be an empty list. So how could that happen? With 2 iterations, you should have returned one cost value for iteration 0, right? Are you sure you didn’t copy over the template code from the previous version of the course? Here’s what the template code should look like for the last section of the two_layer_model function: # Print the cost every 100 training example if print_cost and i % 100 == 0 o…

Thanks, that is sorted, another error arises which is IndexError: list index out of range. this occurs if i access invalid indices in my Python lis . For example, if you try to access the list element with index 10 but your lists consist only of three elements, Python will throw an IndexError telling you that the list index is out of range. but i can’t see it in this instance of the image attached

You can try printing the costs array inside two layer model to see that you actually append to it

[Adesoji]

It’s not printing the cost array

Send me your notebook as a private message and I will have a look

sent as requested to your private message inbox. thank you

you have a problem with indentation. python requires correct indentation. check all your code and if you can’t find the problem, reset your workbook and enter your solution again.

you also have changed in cells where you are not allowed to change. only enter solution where you are asked to, and don’t touch or change anything else.

How to Get a Clean Copy of an Assignment Notebook

If you want to restore the original unmodified state of any of the notebooks or the other files associated with any of the assignments, you can use the “Lab Help” menu of Coursera Labs to do that. The first thing to do is to rename the existing notebook, because this procedure will not overwrite existing files. You need to move the current version of the notebook aside or delete it. The advantage of renaming is that you can later copy any completed work as desired to the fresh copy of the noteb…

i updated the notebook and i aw the code indentation was properly set.

Thanks, it worked but i will refresh the page so i can see the submit button. Thanks so much Teacher jonaslalin. when i become a ML devops Teacher in the future i will mention your name as my Superior trainer.

Besides this i would like to design a neural network in the future called “Sojinet” please how will i do this? please at your leisure time, please can you have an online meeting for me at WAT time? Thanks

I am glad it worked out for you. My recommendation is to get more experience in python, numpy and Tensorflow or PyTorch before you start with an end to end spare time project. You can of course start right now but you will probably have an easier time if you learn to walk before you run. If you want feedback for a project idea, create a new post and describe your idea and what questions you might have. Mentors and other students may have valuable feedback. Best of luck with the rest of the course.

Good morning sir, I applied for MLops scholarship at fourtbrain AI and I am required to deposit $500 . Please sir can you suggest how I can get such amount. Attached is the mail I received from fourth AI.

Congratulations! I have no idea.
