Hi everyone and welcome to the community! We’ve escalated the issue with the Sagemaker domain to our partners. Kindly monitor this topic for updates.
For the kernel crash issue, or any other lab concerns, please refer to this FAQ. You might find item 10 useful.
Lastly, you can ignore the lab due dates set by Coursera. That has no bearing on your grade as long as you have an active subscription. This lab is also practically ungraded because all the code is already provided for you. I think you can press the Submit button even if it’s not completed yet, then you can come back to it later when the bug is fixed.
Hope these help!
