Sample dataset for 3DMV-VQA

[HariniNarasimhan]

For the three step feature extraction, we need the 3DMV-VQA dataset format as mentioned at
https://github.com/evelinehong/3D-CLR-Official

-data   # multi-view images of single-room scenes
   - 00009-vLpv2VX547B_0    # most rooms contain 1000 views while some contain less. 00009-vLpv2VX547B means house 00009-vLpv2VX547B which is the same as HM3D dataset. _0 means it's the first room of the house

can you please let me know a way to download a sample dataset to understand the dataset format, where original dataset is 250GB? . A sample dataset for one room should be okay for understanding. please help
