I am trying to do the lab and am struggling as it continues to say I have not defined X.
In the practice labs for compute cost and gradient descent I do not see anywhere X is explicitly defined and I cannot get past this error to finish the lab.
Can you please advise?

Hi @hahazar
Make sure that you define x in a scope that can be accessed and also check if you haven’t written X instead of x. Also, ensure that you run all the cells especially the one that defines the variable x.

Hope it helps! Feel free to ask if you need further assistance.
All of the functions in this assignment use lower-case ‘x’.
Not ‘X’.
Letter case is important in python variable names.
Thank you.
You’re welcome! happy to help.
