creating config file for custom lidar only dataset (parta2)

[gynaa]

Hello :)

I am trying to train a custom lidar dataset on parta2. I created an annotation.pkl file the way it's described here: https://mmdetection3d.readthedocs.io/en/latest/tutorials/pure_point_cloud_dataset.html

since it only contains the necessary keys i figured i could use custom_3d.py. I took the configuration file available that is used to train parta2 on kitti and changed it to the attached file.

But I get an error: cuda execution failed with error 2. Is there something I am missing? Can someone please help me out?
