My Question

I am trying to reproduce the training on the S3DIS dataset.
The dataset dir is

datasets/
└── S3DIS
    └── Stanford3dDataset_v1.2_Aligned_Version
        ├── Area_1
        │   ├── pantry_1
        │   │   └── Annotations
        │   └── WC_1
        │       └── Annotations
        ├── Area_2
        │   ├── pantry_1
        │   │   └── Annotations
        │   └── WC_1
        │       └── Annotations
        ├── Area_3
        │   ├── pantry_1
        │   │   └── Annotations
        │   └── WC_1
        │       └── Annotations
        ├── Area_4
        │   ├── pantry_1
        │   │   └── Annotations
        │   └── WC_1
        │       └── Annotations
        ├── Area_5
        │   ├── pantry_1
        │   │   └── Annotations
        │   └── WC_1
        │       └── Annotations
        ├── Area_6
        │   ├── pantry_1
        │   │   └── Annotations
        │   └── WC_1
        │       └── Annotations
        └── original_pkl

Do I need to manually perform data preprocessing operations?
