got an error result when change the point_cloud_range?

[yxxxqqq]

we train the model with the different point_cloud_range = [-25.6, 25.6, -25.6, 25.6, -1.0, 3.0], the origin is point_cloud_range = [-51.2, -51.2, -5.0, 51.2, 51.2, 3.0], we train on the nuscenes dataset, but the result is incorrect. Is there any special operation? thanks!
