I can't understand some of your code

Hi! I'm learning 3DSSD recently, your job is great and it is very helpful to me.
In the pointnet2_modules.py
class PointnetSAModuleMSG_SSD(_PointnetSAModuleBase):
def init(self, *, npoint: int,

:param npoint: int
But in the 3DSSD_openPCDet.yaml,
NPOINTS: [[4096], [512], [256, 256], [256, 0], [-1], [256]]
[256, 256] is a list, why it works?

Please follow the program to check inside the code. PointnetSAModuleMSG_SSD is a module and the yaml gives the parameters of several modules.
