Notebook crashed, so I can't edit a cell

Hello everyone.
I have a technical problem that I don’t know how to solve. I’ve already accessed similar topics to mine in this forum, but I couldn’t solve it.

I can’t edit the cells in the notebook for the practical test for week 2 and that’s why I can’t hand in the activity that has a deadline of June 1st.

Help me!

Please post a screen capture image that shows which cell you are trying to edit.

the first one that compiled with error

*Would sending a print not be a case of code exposure?

That cell tests your code. You cannot modify the tests. That’s why editing the test cells is not allowed.

The issue is that your code you added to the compute_cost() function does not work correctly.

Got it! I can only edit cells that start with #UNQ_C2 and # UNQ_C1. Is this expected behavior?

Yes.

ok, thanks
