Issue submitting C1_W2_Assignment

Hello,

I’ve completed this assignment with all the exercises correct according to the checker.
However, when I submit the code, my grade is a 0%.
For every exercise, the error says the following:
“There was a problem compiling the code from your notebook. Details:
name ‘A_ref’ is not defined”, but taking a look at my code, I believe it is.

Any idea to help me submit the exercise?

Thanks in advance

Hi @jdbarrio,

It is for " Linear Algebra for Machine Learning and Data Science"

Best regards,

Hi @jdbarrio,

Does the notebook run without errors when you click in “run all”?

Hi,
I had no errors when I run it all.
However, I was able to solve the problem. I restart the notebook and added again the code.
That solved the issue.

Thanks for your help.

Best regards,

can you help with that, please?
