is that a typo in base.py?

[chivas1000]

I have found in model/base.py the direction prediction are using up1_embedding: if self.direction_pred: x_direction = self.up1_embedded(x2, x1) x_direction = self.up2_direction(x_direction) https://github.com/Tsinghua-MARS-Lab/HDMapNet/blob/7911227d45edb0226422083bc4bc452dc18e6399/model/base.py#L131

why using up_1embedded blocks instead of using up1_direction as the up1_direction is already defined. and will the weights of up1_embedded blocks are affected by the direction prediction?
