Missing file

Hi, thanks for releasing Molmo2-ER!

I noticed that the dataset cards (e.g. Molmo2-ER-RoboVQA) reference olmo/data/spatial_datasets.py as the loader implementation in the “Usage in Molmo2-ER” section. However, I couldn’t find this file in the repository, so it’s currently unclear how to load these datasets. ([huggingface.co](https://huggingface.co/datasets/allenai/Molmo2-ER-SAT?utm_source=chatgpt.com)⁠)

Was this file accidentally omitted, moved to another repository, or is there an updated data loader that should be used instead?

Thanks!
