Pytorch3d: R2N2 Dataloader SPLITS_PATH

[unlugi]

Hello, thank you for the great library!

I am following the Dataloaders tutorial, however I couldn't figure out what the input is to SPLITS_PATH? I know ShapeNet has some pre-determined train/val/splits from previous challenges: is there something for R2N2, as well?

 r2n2_dataset = R2N2("train", SHAPENET_PATH, R2N2_PATH, SPLITS_PATH, return_voxels=True)

Looking through the code I know that a json file is needed but I am stuck!
# Store synset and model ids of objects mentioned in the splits_file.

Thanks!

It refers to the R2N2 split which you can fetch from here: https://github.com/facebookresearch/meshrcnn/blob/master/datasets/shapenet/download_shapenet.sh#L16
