PTQ/QAT Does the centerpoint_qat_pipline.py code only do ptq/qat on the sparse backbone?

[bigsheep2018]

hello Lidar AI Team @hopef ,
I have carefully checked the code and found it seems the centerpoint_qat_pipline.py only insert quant layers in sparse backbone.
Do i miss anything? or if true, do I need to ptq separately with tensorrt for the rest part of the model?
