Model.fit kernel died


What to do while still kernel appears to have died. Fifth time.

Sometimes the servers get overloaded, so this may just be “bad weather in the Cloud”. Wait and try again later. Well, also make sure you aren’t generating any extra output from debugging print statements.

But note that you can submit to the grader without showing your output. Just click “Kernel → Restart and Clear Output”, “Save” and then “Submit Assignment” to check whether your code is accepted by the grader. The grader only needs to call your functions in order to test them.
