Skeleton prediction for rigging?

[cpunion]

I have a dataset contains rigged meshes, which includes vertices, fragments, and skeletons to which the meshes are skinned. How can I use SNAKE to skeleton nodes prediction?

Requirements of skeleton prediction:

1. The predicted skeleton must adhere to a specified number of nodes and a predefined order, ultimately forming a tree structure.
2. The nodes, representing joints, are not typically located on the mesh surface but are positioned at joint locations.
