While I was doing the lab, the kernel crashed but I think I have finished the exercise not sure. Thanks
Kernel crashes if the codes in a cell is not able to run completely in the assigned time length, so if you remember running which code cell caused kernel crashing, you can review your codes again.
I also didn’t get when you mention I finished the exercise not sure?? if you are stating you wrote the codes then running cell successfully is important for exercise to pass through the unittest.
Usually when your kernel crashes you get error log(which provides information on why kernel crashed), kindly post a screenshot of that log without posting any grade function codes
Which Lab and which exercise on that Lab, did you submit for grading before crashing?
