| # PanTS Wan2.2 Fine-tune: Cache, Code, and Step-8000 Checkpoint |
|
|
| This package is the reproducibility bundle for the UCSF run `pants_b16_9k_20260519_215532`. |
|
|
| The run targeted 9000 training steps, but the 2-day Slurm allocation ended after step 8016. There was no traceback, OOM, or NaN in the training log. The last complete saved checkpoint pair is step 8000. |
|
|
| ## What Is Included |
|
|
| - Final non-EMA checkpoint: `checkpoints/checkpoint-8000/transformer/` |
| - Distributed resume checkpoint: `checkpoints/checkpoint-8000/distributed_checkpoint/` |
| - Final EMA checkpoint: `checkpoints/ema_checkpoint-8000/` |
| - Training cache archive: `cache/wan22_pants_v2_softwin.tar.zst.part-*` |
| - Two code snapshots: `code/twoframe_fastvideo_code_snapshot.tar.zst` |
| - Training logs and offline tracker: `logs/` |
| - Metadata and provenance: `metadata/` |
|
|
| The original raw PanTS train/test data is intentionally packaged separately as: |
|
|
| `/scratch/user/yuhwang/artifacts/twoframe/hf_upload/pants_raw_train_test_20260523_102411` |
|
|
| That raw package is better uploaded as a Hugging Face dataset repo. This package is better uploaded as a Hugging Face model repo. |
|
|
| ## Key Paths From Training |
|
|
| - Raw data root: `/scratch/user/yuhwang/dataset/PanTS` |
| - Derived cache root: `/scratch/user/yuhwang/dataset/pants-captions-ldm/cache/wan22_pants_v2_softwin` |
| - Base model path: `/scratch/user/yuhwang/model/Wan2.2-TI2V-5B-Diffusers-merged` |
| - TwoFrame code: `/scratch/user/yuhwang/code/TwoFrame` |
| - FastVideo code: `/scratch/user/yuhwang/code/FastVideo` |
| - Run output: `/scratch/user/yuhwang/artifacts/twoframe/pants_wan22_finetune/pants_b16_9k_20260519_215532` |
|
|
| ## Training Summary |
|
|
| See `metadata/train_args.json` and `metadata/train_health.json` for the full captured FastVideo arguments and log health summary. |
|
|
| Important args: |
|
|
| - Model: Wan2.2 TI2V 5B Diffusers merged local directory |
| - Data cache: `wan22_pants_v2_softwin` |
| - GPUs: 8 |
| - Batch size: 16 |
| - Precision: bf16 |
| - Optimizer: AdamW |
| - Learning rate: `1e-6` |
| - EMA: enabled, decay `0.999`, start step `1` |
| - Checkpoint interval: 4000 steps |
| - Last complete checkpoint: 8000 |
|
|
| ## Restore Cache |
|
|
| ```bash |
| cd 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 |
|
|
| ```bash |
| mkdir -p /scratch/user/yuhwang/code_restore |
| cd /scratch/user/yuhwang/code_restore |
| tar --use-compress-program zstd -xf /path/to/code/twoframe_fastvideo_code_snapshot.tar.zst |
| ``` |
|
|
| Then use the FastVideo and TwoFrame trees from that restored directory, or compare against the git status/diff metadata in `metadata/`. |
|
|
| ## Check Integrity |
|
|
| ```bash |
| sha256sum -c SHA256SUMS.txt |
| ``` |
|
