May I ask how many lines of point cloud data are scanned in your dataset? After converting my 128 line radar into range images, it is still very sparse. If there are too many clicks, an error will be reported: Runtimeerror the expanded size of the tensor (150000) must match the existing size (159400) at non-singleton dimension 0. Target size (150000,3). Tensor size:(159400,3)
I think the 150k points is just an upper bound that we used for the KITTI dataset (with 64 beams). Therefore, you might have to simply increase this in the configuration, e.g., https://github.com/PRBonn/lidar-bonnetal/blob/master/train/tasks/semantic/config/arch/darknet53.yaml
lidar-bonnetal/train/tasks/semantic/config/arch/darknet53.yaml
Lines 77 to 100 in 5a5f4b1

thank you!
