Problem in grading

In my lab, I have passed all the test but well i submitted it is showing I got 20/120. I have tried more than once. I have saved the notebook and then only submitted.

Grader is showing:
There was a problem compiling the code from your notebook, please check that you saved before submitting. Details:
name ‘train_dataset’ is not defined

I don’t know why…

Anyone knows what’s the matter?

can you confirm that you didn’t hard code or didn’t edit anything outside of ###START AND END CODE HERE###

and wrote codes as per the instructions given at the beginning?

I can confirm that I didn’t code outside of start and end code area. And yes I did followed all the instructions.

send screenshot of the grade cells you failed on submission by personal DM

I encountered the same problem and DMed @Deepti_Prasad . Thank you for your help!

are you working on updated version of notebook. Can I know when you took the course @xiaoweiy

Also kindly create a new post even if you get a similar error, chances are your issue might be different and posting on this thread can confuse you as well as other learners.

@Shadow007

can you post a screenshot of your submission grader with details clicked show grader output for cell you didn’t pass here

I believe i am working with the updated one, as I saw a notice when I started the assignment.
i reenrolled lately.

Also, my code passed all local tests. So I believe it’s the grader side issue.

Ma’am I already send the screenshots by personal DM

@xiaoweiy

when did you re-enrolled? you seem to be working in the older version of environment.

So make sure to contact coursera if you just recently enrolled the course and provide them details about when you took the course, they will switch you to the version based on when you took the course.

I did. they asked us to post here. i am just off with their customer support

I am asking for submission grade as you mentioned you did score 20/120, and I need to know that detail @Shadow007

@xiaoweiy

you still haven’t informed me when you re-enrolled the course? also kindly create a separate post as your issue seem to be different than the post creator. you can tag me there, I will check it.

@Shadow007

I am wondering how you scored that 20, which grade cell does it show 20/20?

you are on older version, please create separate post, I will guide you there. don’t wanna mix up with his post due to version mismatch.
