Does the point cloud range need to be symmetrical from zero?

Hi,

When I use point_cloud_range=[-54, -100, -5 54, 100, 3], the prediction results are quite reasonable.

• point_cloud_range=[-54, -100, -5 54, 100, 3]
• voxel_size=[0.075, 0.1389, 0.2]

However, in the case of point_cloud_range=[-54, 0, -5, 54, 108, 3], the results are very poor (most prediction score are close to zero).

• point_cloud_range=[-54, 0, -5, 54, 108, 3]
• voxel_size=[0.075, 0.075, 0.2]

I wonder if the point cloud range should be symmetrical from zero or not.
