C1W2_Assignment_Week2: Gaussian Elimination

[aleksandralez]

Hi !
I am working on Week 2 assignment. All tests went successfully but I am receiving error with score 0/100. The errors are the same: Unable to find object required for grading in your code.
With this output I have no idea where I did mistake and what I need to correct. I’ve seen that this assignment and autograder will be updated on March 13 but still I would like to understand the issue.

Many thanks!

Here is a process for getting a fresh copy of the notebook.

• Open your current notebook.
• Use the File menu and rename your notebook file.
• Use the “Help” menu and select “Get latest version”. This gives you a fresh copy with the original file name.
• Use the File menu and open the new file.
• Use the Kernel menu and select “Restart & Clear Output”.

Then you can work on the new copy of the notebook.
