MA048181

MA048181 is a public reproducibility bundle containing the raw PanTS train/test data package, the derived Wan2.2 training cache, code snapshots, logs, and final saved checkpoints for the UCSF run pants_b16_9k_20260519_215532.

Contents

raw_pants_train_test/

Original raw PanTS data package.

• Raw source path on UCSF: /scratch/user/yuhwang/dataset/PanTS
• Packaged size: about 337G
• Includes ImageTr, ImageTe, LabelTr, LabelTe, metadata.xlsx, and PanTS repo README/license/download scripts.
• Restore instructions: raw_pants_train_test/raw/RESTORE.txt

Observed raw data summary:

• ImageTr: 9000 cases, 9000 files, about 296G
• ImageTe: 901 cases, 901 files, about 27G
• LabelTr: 9000 case dirs, 260999 files, about 45G
• LabelTe: 901 case dirs, 26129 files, about 4.0G

model_cache_code_step8000/

Derived training cache, final checkpoint, and code snapshot package.

• Derived cache source path: /scratch/user/yuhwang/dataset/pants-captions-ldm/cache/wan22_pants_v2_softwin
• Packaged size: about 161G
• Main train manifest: captions_embedded/source_train.jsonl
• Manifest row count: 53,784
• Contains VAE latent cache, text embedding cache, captions, embedded-caption manifests, code snapshot, logs, and checkpoints.

Final complete checkpoints:

• non-EMA: model_cache_code_step8000/checkpoints/checkpoint-8000/transformer/
• EMA: model_cache_code_step8000/checkpoints/ema_checkpoint-8000/
• distributed resume state: model_cache_code_step8000/checkpoints/checkpoint-8000/distributed_checkpoint/

Important status note: training targeted 9000 steps, but the 2-day Slurm allocation ended after step 8016. The last complete saved checkpoint pair is step 8000. Logs showed no traceback, OOM, or NaN.

Data Layers

This repository intentionally keeps three layers together but separated by directory:

1. Raw PanTS train/test data: raw_pants_train_test/
2. Derived VAE latent cache: model_cache_code_step8000/cache/wan22_pants_v2_softwin.tar.zst.part-*
3. Derived text embedding cache: inside the same cache archive, under text_embeddings/

Restore

Restore raw PanTS:

cd raw_pants_train_test/raw
cat PanTS.tar.zst.part-* > PanTS.tar.zst
tar --use-compress-program zstd -xf PanTS.tar.zst

Restore derived cache:

cd model_cache_code_step8000/cache
cat wan22_pants_v2_softwin.tar.zst.part-* > wan22_pants_v2_softwin.tar.zst
tar --use-compress-program zstd -xf wan22_pants_v2_softwin.tar.zst

Restore code snapshot:

mkdir -p code_restore
cd code_restore
tar --use-compress-program zstd -xf ../model_cache_code_step8000/code/twoframe_fastvideo_code_snapshot.tar.zst

Integrity

Each subpackage has its own SHA256SUMS.txt and PACKAGE_COMPLETE marker.

cd raw_pants_train_test && sha256sum -c SHA256SUMS.txt
cd ../model_cache_code_step8000 && sha256sum -c SHA256SUMS.txt

Notes

The base Wan2.2 model binaries are not duplicated here. The fine-tuned transformer checkpoints and the base-model symlink map are included in model_cache_code_step8000/metadata/base_model_symlinks.txt.
