Error while training

Hello! I've made it this far with setup, but I'm a bit stuck as to what might be the problem here. Thanks!

Loading SfM point cloud... Traceback (most recent call last): File "/mnt/c/users/dell/documents/github/sugar/train.py", line 162, in refined_sugar_path = refined_training(refined_args) File "/mnt/c/users/dell/documents/github/sugar/sugar_trainers/refine.py", line 361, in refined_training pcd = fetchPly(ply_path) File "/mnt/c/users/dell/documents/github/sugar/gaussian_splatting/scene/dataset_readers.py", line 112, in fetchPly normals = np.vstack([vertices['nx'], vertices['ny'], vertices['nz']]).T File "/home/bc/miniconda3/envs/sugar/lib/python3.9/site-packages/plyfile.py", line 827, in getitem return self.data[key] File "/home/bc/miniconda3/envs/sugar/lib/python3.9/site-packages/numpy/core/memmap.py", line 335, in getitem res = super().getitem(index) ValueError: no field of name nx

So, a bit more context and the solution. I'm using my own custom data and calibrating outside of colmap. Turns out that the converter I'm using to bring my cameras into colmap wasn't including normals in the points3D.ply file. Once they were added, the error went away and I got a great result.

Hello @briancantwe,

Nice, I'm glad you managed to solve this problem!

Feel free to share the results you got (well, only if you want to of course, it may be something you don't want to/you can't share), as it may be interesting to see how SuGaR performs on various scenes!

Итак, немного больше контекста и решение. Я использую собственные данные и калибрую вне colmap. Оказалось, что конвертер, который я использую для переноса данных с камер в colmap, не включал нормали в файл points3D.ply. Как только они были добавлены, ошибка исчезла, и я получил отличный результат.

Hi! Could you describe in more detail the process of transferring data from colmap? Let me take advantage of your experience, thank you in advance!
