DLS C4W3 - Unet Kernel appears to have died


I have finished yesterday (30-mai) the last program assignment of week 3 of CNN course. Although the preliminary tests works well (correct answers - “All tests passed!”), when running the Item 4 (" Train Model") the kernel dies (see attachment):

It is using Tensorflow 2.9.1 version.

Could you help me on this issue. Just missing solve this point to finish this week.

Thank you in advance.

Coursera is working on a fix for this issue.
Meanwhile, you can try to submit your work for grading. The grader doesn’t trigger the kernel issue.


Hey Vivian; can you reply-back if submitting worked for you? It didn’t for me.

What error you are getting while submitting your work?
