Open3d Error

[wyiguanw]

Hello, Thanks for the great work! I have tried colab version, it works well. But when I try to deploy it on my computer, this error is raised. is there any solution?

system: Ubuntu

[Open3D Error] (static std::tuple<std::shared_ptr<open3d::geometry::TriangleMesh>, std::vector<double, std::allocator<double> > > open3d::geometry::TriangleMesh::CreateFromPointCloudPoisson(const open3d::geometry::PointCloud&, size_t, float, float, bool, int)) /root/Open3D/cpp/open3d/geometry/SurfaceReconstructionPoisson.cpp:732: Point cloud has no normals

hey, did you find any solution?

I‘ve solved it, this error is caused by uncorrect parameter in function. The o3d.geometry.TriangleMesh.create_from_point_cloud_poisson() 's function signature is

open3d.geometry.TriangleMesh create_from_point_cloud_poisson(
    pcd: open3d.geometry.PointCloud, 
    depth: int = 8, 
    width: int = 0, 
    scale: float = 1.1, 
    linear_fit: bool = False
) -> Tuple[open3d.geometry.TriangleMesh, open3d.utility.DoubleVector]

.There is a uncorrect parameter n_threads=-1 pass to it.
My open3d version is 0.10.0.0 in Ubuntu22.04
