example script list index error

[caisilus]

I was trying to run the example script, but ran into an error:

Traceback (most recent call last):
File "test_monorec.py", line 41, in <module>
batch, depth = dataset.__getitem__(index)
File "../data_loader/kitti_odometry_dataset.py", line 252, in __getitem__
keyframe_pose = torch.tensor(dataset.poses[index + self._offset], dtype=torch.float32)
IndexError: list index out of range

I found out that dataset poses for sequence 07 is an empty list. In this code below in kitti_odometry_dataset.py string constant is "poses_dvso". However, examples poses dir has name "poses_dso".

if self.use_dso_poses:
    for dataset in self._datasets:
          dataset.pose_path = self.dataset_dir / "poses_dvso"
          dataset._load_poses()

It seems that changing the constant to "poses_dso" fixes the error.

Hi @caisilus, thanks for pointing it out!
Actually, I just did a fix on that right before you posting the issue: f648ed7.

Could you please check if it works for you?

Hello @Yelen719, thank you for the answer!
It seems that the problem is still relevant. In the example/data/kitti folder, there is only a folder named "poses_dso", and no folder for the path "example/data/kitti/poses_dvso"
In f648ed7 you changed string constant to the value "poses_dvso" that doesn't match the name of the folder (poses_dso). Should I download any dvso poses or the existing folder should be renamed to "poses_dvso"?

Sorry for the mistake.

The folder example/data/kitt/poses_dso should be renamed to example/data/kitt/poses_dvso in this case.
I've pushed the fix. Please let us know if you face any other issues.

Best,
Nan
