Hello community!
How are you? 
I am having the following problema when I submit my lab for trading:
Cell #1. Can’t compile the student’s code. Error: ModuleNotFoundError(“No module named ‘imageio’”)
I did the exercises and all the tests inside the notebook passed, but it seems that for some reason the system that performs the grading has some problem in the compilation that does not allow it to proceed.
Thank you very much!
Hey @cmdepi,
Seems like there is an issue with the auto-grader. Let me report it to the team with an urgent priority, and we will let you know once the issue is resolved. Thanks for reporting the issue 
Cheers,
Elemento
Having the same issue as above
Hi everyone! We have reported this and the team is working on it. Will update this thread as soon as I hear from them. Thank you and sorry for the inconvenience!
Hello again! Our engineer is now actively working on the fix. You might be able to retry the submission after an hour.
Hi everyone! Please reopen the lab from the classroom and try submitting. Hope it works now!
Can confirm it’s now working again (at least for me, who previously had the issue). Thanks for the quick turnaround!
