AttributeError: 'add' object has no attribute 'v'

[Zkjoker]

By some other algorithm, I got an ply file which is in smpl format. And I want to use your code to generate the skeleton. However, there is an error:

same topology as STAR or SMPL. Mesh has {skin_mesh.v.shape[0]} vertices, {sv.v.shape[0]} expected')
AttributeError: 'add' object has no attribute 'v'
``
Can you please tell me how can i use my own ply human surface to get the inside skeleton?
Thank you!

Can you check the content of the variable skin_mesh just before this error occurs? Moreover, if you execute skin_mesh.show() it should show you your mesh.

thank you , I have solved the problem. but there is another issue: /home/anmo1/OSSO/osso_venv/lib/python3.8/site-packages/scipy/sparse/linalg/_dsolve/linsolve.py:206: MatrixRankWarning: Matrix is exactly singular warn("Matrix is exactly singular", MatrixRankWarning) /home/anmo1/OSSO/osso_venv/lib/python3.8/site-packages/chumpy/optimization_internal.py:287: UserWarning: sparse solve failed, falling back to lsqr warnings.warn("sparse solve failed, falling back to lsqr")

Does your algorithm require the orientation of characters? Thank you！

This time I adjusted the character to face straight ahead, but it still reported an error and couldn't get the expected skeleton. How can I solve this problem so that I can get the right bone? Thank you!

This problem should be solved by the last commit. Can you pull and try again?

Basically you provided a mesh without faces, which the code did not support. Now the code supports input mesh without faces.

Thank you for your assistance in solving the problem. Excellent work!
