error when initializing the pose in add_view_v2

[lqzhao]

Hi, thank you for your excellent paper. In the original implementation, the pose between view_idx_prev and view_idx is initialized via self.gs_render_local.gaussians.init_RT(None). It can be run normally.

However, when I tried to initialize the pose with gt values in add_view_v2 (e.g., self.gs_render_local.gaussians.init_RT(pose=gt_pose[view_idx_prev]) ), I encountered the following issue:

Traceback (most recent call last):

xyz = self.P[0].retr().act(xyz)
TypeError: LieGroup.retr() missing 1 required positional argument: 'a'

How can I solve this? Thanks!
