Add hooks to a module (make sure the hooks are removed), cannot deepcopy OBB model

[TianL123]

When I use this YOLOv8 pruning routine, I cannot carry out deepcopy, I use OBB model, I suspect it is caused by hook operation, but I do not know how to solve it.
BUG:Only Tensors created explicitly by the user (graph leaves) support the deepcopy protocol at the moment
