model settings ablation

[petwu]

Hey, I have some questions about table 8 from your paper:

• Which parameters in the config file do I need to tweak to achieve the changes from the "Backbone Size" column?
• The FPS numbers suggest that the last row corresponds to model which you compare against baselines in table 2 and for which the config files can be found in this repo (e.g. configs/p3former/p3former-8xb2_3x_semantickitti.py), right?
• How did you calculate the "Model Size" column? When I count the parameters for the provided P3Former configs I get ~71.6M parameters, which corresponds to none of the values in the table.

I appreciate any help. Thanks!
