Did you run both of these scripts without errors, as described in the data processing readme?

1. data_processing/wai_processing/download_scripts/download_unrealstereo4k.py
2. data_processing/wai_processing/scripts/conversion/unrealstereo4k.py

Can't the dataset downloaded from https://huggingface.co/datasets/facebook/map-anything be used directly? Do I need to download the original dataset as well?

[cr333]

You will need to download and process the dataset yourself.

As you can see at https://huggingface.co/datasets/facebook/map-anything/tree/main/wai_data/unrealstereo4k/00008, the Huggingface data repo only contains the covisibility file, not the actual dataset.
