I want to use one GPU for semantic segmentation on S3DIS, but there is not enough memory, so how can I reduce the number of points in the point cloud?

Hi!

thanks for your interest in our work!
Easiest way is to increase the voxel size, e.g., data.voxel_size=0.05 in the config file / CLI. However, this comes with a decreased performance.

Best,
