Added by mentor: C4W1 Assignment, function train_val_split
{removed by mentor}
expected output is correct, what seems to be the problem?
Lets go to Naive Forecast

expected output aligned
here’s the problem

This is really giving me a headache, I can’t progress to the next stage without resolving this, I have been on this since.
Look what I am getting for train_val_split
naive_forecast, I cant fathom the problem
Hello @Deloni,
I don’t mentor this course, but since it is giving you a headache, I am going to give it a try and share what I saw:
Let’s look at time_step=SPLIT_TIME. It means the function is taking an input argument called time_step, and if the value of time_step is not specified when calling the function, then it is assumed to be SPLIT_TIME. For example, calling train_val_split(something1, something2) without the 3rd argument means to assume it to be SPLIT_TIME.
Here, it is important to note that, time_step is the actual name of the input argument, but NOT SPLIT_TIME. SPLIT_TIME is like the default value for time_step. It means that, if one of those assignment’s test does specify time_step to be something, like time_step = 20, then only if you have used time_step as the variable name inside the function allows the function to actually use the value of 20. You got me? time_step is the variable name to be used in the function, not SPLIT_TIME.
Hope this will solve some of the problems, if not all. If there are other problems, please reply and I hope mentors of this course will help.
Good luck!
Raymond

I see my mistake, thank you so much for your correction. using time_step variable and it worked fine perfectly
That’s great!
Cheers,
Raymond
yes you are correct!
it worked, thank you!
