If you see the first code block z_student has shape (1,students) while z_question has shape (questions,1) .

Hi @jbuddy_13 - not sure I understand what you mean here, what’s “the first code block”? If I put a breakpoint before the # Transformed parameter line, then I see

ipdb>  z_student.random().shape
(5, 3)
ipdb>  z_question.random().shape
(3, 5)

, I don’t understand when z_student has shape (1,students) - any chance you could clarify?
