Hello,
Sorry for this very late response.
Yes, in order to import lightconvpoint.knn, you need to import torch first.
This is something that will be changed.

Hi,
I have question about the way you select the radius can you please explain why you choose:
- the EMA method
- 8192 as the number of the support point for the larges scales datasets (as i understand 8192 support points are selected randomly after the selection the voxel size like in the formula cited in page 7)
- the way you select the support point , as i understand it do not take into account the density of points
can i have further details please?

Hello,
Sorry for very late response.
- What is EMA ?
- We select the points randomly in each voxel, the whole selection process for quantized sampling is not purely random.
- In quantized sampling, the density of the point is taken into account implicitly: as we select in the voxels, we favors low density locations. However if the density variations are very high and the number of support is high, you still might end up with density problems.
