Exercise 4: Index Error

I am nearly at the end of the course and can not determine why this error occurs.

Your get_best_split() function is using incorrect indexing.

Is it because of anything wrong in this code:

Please don’t post your code on the forum.

I don’t see any issues there.

Maybe the problem is in compute_information_gain().

Note: x_train does not exist inside the context of compute_information_gain(). There is an ‘X’ variable, but no x_train.
