Different voxels sizes #77

Open ahmedius2 opened 3 months ago

ahmedius2 commented 3 months ago

Hello, thanks for this wonderful project.

I want to train DSVT on nuscenes with different voxel sizes to have models with different execution times and accuracy tradeoffs. For example, Centerpoint has 0.075 and 0.1 size voxel variants. Could you tell me how I should configure the DSVT in the yaml file for different voxel sizes such as 0.2 and 0.4? I want to keep the point cloud range similar (-54 +54) so there is a fair comparison.

If you wish to modify the voxel sizes, it's essential to adjust several parameters in the configuration file. These include the sparse shape, window shape, stride, and others. I strongly recommend thoroughly reviewing and understanding the code before making any changes to ensure everything is appropriately adjusted and functioning correctly.
