ScanNet v5 axis-white SFT data

This package contains the user-approved ScanNet v5 SFT data used for the Qwen3.5-0.8B training and evaluation runs.

Contents

• scannet_v5_axiswhite_edbffd1_stable_train.tar.zst: stable training split, 8,000 samples and 8,000 PNG images.
• scannet_v5_axiswhite_edbffd1_stable_eval.tar.zst: stable evaluation split, 1,000 samples and 1,000 PNG images.
• scannet_v5_axiswhite_edbffd1_diverse4_train.tar.zst: diverse4 training split, 8,000 samples and 8,000 PNG images.
• scannet_v5_axiswhite_edbffd1_diverse4_eval.tar.zst: diverse4 evaluation split, 1,000 samples and 1,000 PNG images.
• metadata/: source manifests.
• SOURCE_IDENTITY.txt: source version and accepted exception.
• SHA256SUMS: package checksums.

Download

This public dataset uses manual access approval. Request access on the dataset page first, then authenticate and download:

hf auth login
hf download XueyingJiang/experiment_data --repo-type dataset --local-dir ./experiment_data
cd ./experiment_data
sha256sum -c SHA256SUMS

The download command is resumable. Running it again continues or verifies files already present in the local directory.

Extraction

Run all commands in the same destination directory:

tar --use-compress-program=unzstd -xf scannet_v5_axiswhite_edbffd1_stable_train.tar.zst
tar --use-compress-program=unzstd -xf scannet_v5_axiswhite_edbffd1_stable_eval.tar.zst
tar --use-compress-program=unzstd -xf scannet_v5_axiswhite_edbffd1_diverse4_train.tar.zst
tar --use-compress-program=unzstd -xf scannet_v5_axiswhite_edbffd1_diverse4_eval.tar.zst
sha256sum -c SHA256SUMS

After extraction, data is arranged under stable/{train,val} and diverse4/{train,val}.

Visual convention

For the two local-coordinate vector tasks, the true 0.5 m scale is integrated into one positive X, Y, or Z axis. The segment from the coordinate origin to the 0.5 m tick is white and labeled 0.5 m.

Known accepted exception

The user accepted that stable training sample scannet_v5_stable_train_004274 has a roll reference arc whose projection appears close to a straight line. The full validator was interrupted at this sample, so this package must not be described as having passed that validator without exception.
