Hi,
i am currently at C1_W2_Linear_Regression. Although all the tests in the lab had passed, I got this error after submission:
Cell #23. Can’t compile the student’s code. Error: NameError(“name ‘n’ is not defined”)

which is funny because I didn’t use a variable named “n”. Please help.

Br,
Piotr

hello @Piotr_Porzucek

Welcome to our community.

So, this error happens only after submission, but otherwise all the cells have run without error and all the tests have passed. If so, please DM the notebook to me and I will take a look.
