I want know where have standard answer for C1W2_Assignment?

I don’t understand your question, if you open the lab in coursera you can follow up with the explanations inside the script!

It seems don’t have hints :smiling_face_with_tear:

You have plenty there, how much more do you want, maybe you want a robot to type for you…

Also its not allowed to publish code solutions publicly in the Forum!

I mean hints like this, I want to compare my code and the code in hints.

There are no “official” solutions for any of the assignments in this specialization or any of the others here. The reason is that it would just enable cheating.

There are unit tests in the Gaussian Elimination notebook, just like the one you point to from the C1 W3 assignment. You can always open the unittest file and examine what the test code is doing to get more ideas of how to debug your code when the tests fail.

What Gent says matches my interpretation of how I would interpret “hints”: they spend quite a bit of effort in the instructions in the notebook walking you through the steps of the calculations here. Now you just need to translate that into python code. My recommendation is to take one of the test cases you fail and then literally work it out step by step with pencil and paper, so you know exactly what should be happening. Then put print statements in your code to figure out where your code differs from what you know should be happening.

Note that very few courses provide hints that are so detailed as to give away the entire solution.

Thanks for your patient response :hearts:
After finished the assignment successfully, I think my answer is not a neat and simply one, where I can find a better one to study?

There are no official examples to study. I can take a look as an individual matter. I will send you an DM about how we can do that.

After following the lecture content, if there are no hints like Machine Learning specialization. It is really difficult for a beginner to type code for the second-week assignment. Huge Gap! I stagged 2 hours but have nothing idea to finish this assignment. I have to choose to quit! Not friendly for beginners at all, this course.

I agree, this course (designed by a different instructor) has a different approach.
