Hello,

I am using cph.registration.registration_filterreg for registering various pointcloud iteratively. The memory keeps growing after each iteration and after about 280 iterations i get CUDA out of memory error.

Environment:

  • Windows 10
  • Python 3.7.9
  • Intel Core i7-9700k
  • NVIDIA GeForce GTX 1660, 6GB

Is there anything that can be done apart from executing this on a linux environment?

Thank you for the reporting!
I would like to investigate this bug.
Can you share your test code and data?

Hello,

I have the same issue as sujit-rai while I am using cph.registration.compute_fpfh_feature
I am using a dataset with around 13 million points, and my test code is basically the same as yours.

Thanks!
I think this error is purely out of memory.
Try reducing the number of points.
