Getting cudaErrorMemoryAllocation out of memory about cupoch HOT 6 OPEN

Hi @neka-nat
Thank you for your reply. Some data I cannot put publicly. So I’m finding some workaround so that l can share here easily. I will update soon. Thank you so much again.

Hi @neka-nat
I tested one point cloud data. You can use the file called L003.ply from here: https://1drv.ms/u/s!Amlc6yZnF87psX6hKS8VOQllVvj4?e=yWhrYX
This file L003.ply has more than 39million points.

Same error I am getting for this L003.ply also:

cl, ind = voxel_down_pcd.remove_statistical_outlier(nb_neighbors=20, std_ratio=2.0)
MemoryError: std::bad_alloc: CUDA error at: /home/runner/work/cupoch/cupoch/third_party/rmm/include/rmm/mr/device/cuda_memory_resource.hpp:69: cudaErrorMemoryAllocation out of memory

from cupoch.

I am still investigating the problem, but I found that it was failing to allocate memory during flann tree construction.
It may take some time to solve the problem.

Hi,
Thanks for the report!
If possible, could you please share the pointcloud file with the error?

Hi @neka-nat
Do you have any advice on how do I fix this? I tried too much downsampling but it's affecting the result. Let me know if you have any suggestions. Thank you in advance.
