C1_W2_Linear_Regression: Week 2 practice lab - Code Assignment - Stuck at 41/100 score

Course Q&A Machine Learning Specialization Supervised ML: Regression and Classification

I’ve completed both the exercises. But cannot move past 41/100 score.

I’ve ensured that I update only with the sections markeds as

### START CODE HERE ###

### END CODE HERE ###

I did not touch any other section. I’ve run the code, 1 step at a time and every test should “passed” i.e. results as expected. I’ve also verified the code with Hints provided. Don’t see any issue. Yet, when I submit, I get only 41/100. Not sure what I’m doing wrong. Can anyone help please?

Passing the tests in the notebook does not prove your code is perfect.
The grader uses different tests than those in the notebook.

The first thing to check is - does the code you added use any global variables, when you should be using a function parameter?

And, have you hard-coded any parameters, when you should be using a computed value?

Hi Tom,

Thanks for the quick response.

When I use the code in deeplearing.ai lab, it gets stuck at 41/100. But, when I used the exact same code in Coursera Lab, it worked. I am not sure what is the issue with deeplearing.ai lab, but given that I got 100/100 in Coursera Lab, I am pretty sure that the issue is not with my code.

Please check your personal messages for instructions.

Have you modified the notebook file name? That will confuse the grader.

I am also facing similar issue. I don’t see any issue with my code. @Rudraeon what was the fix recommended by @TMosh
