MeshVectorHeatSolver fails when the shape comes form DT4D dataset.

Hi,
I’d like to compute the connection Laplacian of 3D triangle mesh via L=pp3d.MeshVectorHeatSolver(verts,faces).get_connection_laplacian(). However, I find that it fails when it runs on the DT4D dataset. The code gives the following error message.

How to solve this problem??

This probably means that the input mesh is nonmanifold. Consider running mesh repair algorithms e.g. to split nonmanifold edges. MeshLab has several nice such routines, including with python bindings.

Thanks, I'll try it.
