Cell #8. Can’t compile the student’s code. Error: KeyError(‘father’,)

Hi @kvamvake,
‘father’ and ‘mother’ are two args pass to cosine_similarity() function called within the print() statement for the first test case.
Please check the code for the cosine_similarity() and make sure all the calculations follow the formulas given in the instructions note.
