Hello @canxkoz,
I am working on my last assignment C1_W3_ex:1 , I am getting an error on ex 1 for while I have tried but unable to figure out error
can you please take a look through my lab as today is second last day of deadline

lab_id : wrenygmb

The error I got is

Extracting (2, 2, 2) sub-volume

Error: Wrong shape. for variable 0.
Error: Wrong shape. for variable 1.
Error: Wrong output.

AssertionError: Not all tests were passed for get_sub_volume. Check your equations and avoid using global variables inside the function.


Hello @Rehan_Ahmed,
Thanks a lot about getting back to me. Unfortunately I do not have access to your notebook. I see that you have created a new issue on Discourse about the same issue. As I was not able to replicate the error that you were receiving, this seems like it is an internal error with the notebook.

I know that @Mubsi has internal reach to notebooks. I want to tag him on my response for your issue to be resolved.

You do not have to worry about the deadline of your assignment/lab as the date you complete your assignment does not contribute to your passing grade. Coursera platform automatically renews the deadlines.

I just read the community forum and other posts:

I saw some several hints provided by other learners who shared how they fixed this problem. Maybe their hints can be helpful to you.

Once again, thanks a lot for asking questions and making use of the Discourse Community.
