question about the speedup branch

[HannahHaensen]

When running the speedup branch i run into the following error:

FEngine resolved backend: OpenGL
Traceback (most recent call last):
  File "/home/hannah/Documents/GitHub/MonoGS/slam.py", line 252, in <module>
    slam = SLAM(config, save_dir=save_dir)
  File "/home/hannah/Documents/GitHub/MonoGS/slam.py", line 110, in __init__
    self.frontend.run()
  File "/home/hannah/Documents/GitHub/MonoGS/utils/slam_frontend.py", line 368, in run
    eval_ate(
  File "/home/hannah/Documents/GitHub/MonoGS/utils/eval_utils.py", line 70, in eval_ate
    latest_frame_idx = kf_ids[-1] + 2 if final else kf_ids[-1] + 1
IndexError: list index out of range

i also checked here: #5

but this seems not to be my issue, the general branch runs just fine.
