I think that’s the answer that you get if you forget to use the “shuffled” name list as your input in your model function. They gave you the code to randomly shuffle the last before you start. If the name that is input at iteration 0 is Aachenosaurus, that’s another indication that this is the mistake you’ve made. That is the very first name on the original list, as you can see from the cell early on where they show you the list. Here’s another recent thread about that type of issue.
