GRADED FUNCTION: get_best_split

The function definition I created succeeds in the displayed test but fails in the hidden test with error:
IndexError: index 5 is out of bounds for axis 0 with size 5

2

The grader uses different tests than the ones in the notebook.

Check that your code can work for any size and shape of dataset. Avoid using constant values when a variable would be a better choice.

3

All the other tests I have passed. Why does it not check each test as correct or incorrect, as is usual? For this reason, I cannot get a pass

4

The tests in the notebook are not exhaustive.

It’s possible for a function to pass its tests, but still cause failures of other tests that use that function.

5

But why is it not considering the other tests that have passed hidden tests

6

The grader runs totally independently from the tests inside the notebook.
It has a totally different set of tests.
