Dataset

[Dejavu-h]

When I run
python3 scripts/precache.py ../data/kitti/data_odometry_velodyne/dataset kitti_tracking /path/to/cache --config config/kitti-tracking.yaml
I get an error.
Based on the error messages you shared earlier, the issue is in the MOS4D dataset module when processing point clouds. The specific error occurs because the code is trying to apply a boolean mask to a tuple containing arrays, and one of those arrays is empty.
The first error was:
TypeError: only integer scalar arrays can be converted to a scalar index
And the second error was:
IndexError: boolean index did not match indexed array along dimension 0; dimension is 0 but corresponding boolean dimension is 124668

I think the problem is that this dataloader uses the KISS-ICP Kitti dataloader for which we updated the API.

Can you checkout at the branch benedikt/fix_dataloaders to see if this fixes your issue?
