CO3D evaluation preprocessing fails with single_sequence_subset

[cavalier501]

Hi, thanks for releasing VGGT!

When following the CO3D evaluation instructions, the preprocessing step fails if the dataset is downloaded using the official CO3D --single_sequence_subset.

The script evaluation/preprocess_co3d.py expects the file:

set_lists/set_lists_fewview_dev.json

However, when downloading the dataset using:

python co3d/download_dataset.py --download_folder --single_sequence_subset

the dataset instead contains files like:

set_lists/set_lists_manyview_dev_0.json
set_lists/set_lists_manyview_dev_1.json
set_lists/set_lists_manyview_test_0.json

and set_lists_fewview_dev.json is not present.

As a result, preprocessing fails with:

FileNotFoundError: set_lists/set_lists_fewview_dev.json

Is the evaluation pipeline expected to work with the single_sequence_subset, or should the full CO3D dataset be used instead?

Thanks!

I encountered the same problem. Have you solved it?
