AttributeError: 'Node' object has no attribute 'leq_child'

Hi, thanks for your detailed codes.

I followed the steps in 'train.sh', training a vanilla teacher, extracting occuapcy and distilling the student, these three steps go smoothly but when I run the finetune command, the bug in the title appears, do you have any ideas?
