Risk Models Using Tree-based Model

[AREPRADEEPTHI_2025]

I AM DOING THIS ASSIGNMENT, AND I AM NOT ABLE TO COMPLETE THIS ASSIGNMENT AFTER SO MANY TRIALS. CAN I GET HELP WHERE AM GOING WRONG? Code Cell UNQ_C1: Function ‘fraction_rows_missing’ is correct.

Code Cell UNQ_C2: ‘dt_hyperparams’ is correct.

Code Cell UNQ_C3: Unexpected error (ValueError(‘Event times and predictions must have the same shape’,)) occurred during function check. We expected function `cindex` to return type <class ‘bool’>. Please check that this function is defined properly.

Code Cell UNQ_C4: Function ‘bad_subset’ is correct.

Code Cell UNQ_C5: Unexpected error (ValueError(‘Event times and predictions must have the same shape’,)) occurred during function check. We expected function `cindex` to return type <class ‘bool’>. Please check that this function is defined properly.

Code Cell UNQ_C6: Unexpected error (ValueError(‘Event times and predictions must have the same shape’,)) occurred during function check. We expected function `cindex` to return type <class ‘bool’>. Please check that this function is defined properly.

If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.

This dependency may be the cause of the errors.

C2_W2 UNQ_C1: Wrong Shape

hi @horatius83 Based on the hints provided before the grade function cell, you require to write a single.code for return function which should not include any global variables and use the below pointers under hint section [Screenshot_20250705_182627_Chrome] I hope you are not using DataFrame as per hint mentions because for the grade function dataframe is being recalled by df. So use the sum function to dataframe and .isnull() to which apply the second point hint i.e. any() and the set the …

you probably using incorrect function or variable name somewhere causing mismatch shape
