Hello,

I am getting :
Cell #23. Can’t compile the student’s code. Error: NameError(“name ‘lr_model’ is not defined”)

i do not know , who should define this. it is not part of this exercise so it should be somewhere maybe inutil ??? please help.

Thanks

Hi,

@Zvi_Boiangou you’ll need to share your code so that anyone can see what’s causing the issue. Without seeing the code, it’s difficult to pinpoint the exact problem.

Thanks.

I doubt anyone could figure this out without seeing the complete notebook and all the associated files. Also note as a general matter that we’re not supposed to share solution code in a public way on the forums. The first question is where lr_model should be defined. Look for the cells in the notebook that contain “import” commands. Did you modify any of them? E.g. perhaps accidentally turn them from code cells into “markdown” (documentation) cells. If the import commands look correct, then maybe one of the accompanying files in your assignment was not correctly initialized or has been modified. You can click “File → Open” and then check the contents of any utility “dot py” files that are part of the assignment. Here’s a thread about how to get clean copies of the notebook and the rest of the files in the assignment (read all the way to the end of the article).

Hello,

The lr_model is not part of the exercise of this task, thus it should be defined as a part of some package.

i am getting this issue even in the middle of the task when the lr_ARR_quantile_test is called :

NameError Traceback (most recent call last)

Hello @Zvi_Boiangou

UNQ_C6 (UNIQUE CELL IDENTIFIER, DO NOT EDIT)
def lr_ARR_quantile(X, y, lr):

for code
Calculate the baseline risks (use the function that you just implemented)

you are suppose to use only lr and not lr_model.
