• I have searched for similar issues.
• For Python issues, I have tested with the latest development wheel.
• I have checked the release documentation and the latest documentation (for main branch).

Describe the issue

Attempting to use the orient_normals_consistent_tangent_plane method in Open3D, the function does not recognize lambda as a valid argument name.

Steps to reproduce the bug

import numpy as np
import open3d as o3d
points = np.random.random((100,3))
pcd = o3d.geometry.PointCloud(o3d.utility.Vector3dVector(points))
pcd.estimate_normals()
pcd.orient_normals_consistent_tangent_plane(k=5, lambda=0.1)

Error message

SyntaxError: invalid syntax

Expected behavior

Just an other name for the argument lambda for example lambda_

Good catch, but I was faster. :D
I fixed it already in #7096 and it got merged yesterday. ;)

Thanks for reporting, though!

Oh, also as a workaround in 0.18.0 you can use the following:

pcd.orient_normals_consistent_tangent_plane(k=5, **{"lambda": 0.1})
