| # synth_captioning |
| |
| Captioning pipeline for the synthetic PinPan datasets (`enrue1893/PinPan_Train_Syn`), extracted |
| from `JointGen-backup`. Perspective-crop rendering happens upstream (external simulator); this |
| bundle only covers the **captioning stage**: pulling pre-rendered panorama + 5 perspective clips |
| per sample and generating structured JSON captions with a locally-served Qwen VLM |
| (`Qwen/Qwen3.6-27B`). |
| |

| Import chain: `stream_process_pinpan_train_syn_captions_only.py` -> `caption_qwen36_8k_5traj.py` |
| (`q5`) -> `caption_qwen36_pano_perspective_pair.py` -> `pano_conditioning.py` (`equi2pers`). |
|
|
| ## Setup |
|
|
| 1. `python -m venv venv && source venv/bin/activate && pip install -r requirements/qwen36_env.txt` |
| 2. Serve the captioning model: see `qwen36_test/README.md` |
| (`python qwen36_test/vllm_serve_wrapper.py serve Qwen/Qwen3.6-27B --host 0.0.0.0 --port 8000 ...`). |
| 3. **Fix the hardcoded conditioning path.** `caption_qwen36_pano_perspective_pair.py` defines: |
| ```python |
| DEFAULT_PANO_CONDITIONING_PATH = ( |
| "/home/work/.local/khs/Projects/PanoWorld/cosmos_predict2/_src/predict2/utils/pano_conditioning.py" |
| ) |
| ``` |
| That absolute path won't exist on a new machine. Point it at the copy included in this bundle |
| (`data/_5traj_4view_analysis/pano_conditioning.py`), e.g. edit the constant or symlink it into |
| place before running. |
| 4. Put an HF **write** token at `data/dataset_streaming_template/.hftoken` (gitignored, not |
| included here) — used to upload results to `OUTPUT_REPO`. Override the input/output repos, |
| `QWEN36_TEST_DIR`, `VLLM_BASE_URLS`, `VLLM_MODEL`, etc. via env vars (see the top of |
| `stream_process_pinpan_train_syn_captions_only.py`). |
| 5. Run: |
| ```bash |
| cd data/dataset_streaming_template |
| python stream_process_pinpan_train_syn_captions_only.py |
| ``` |
|
|
| Source: `JointGen-backup` (khs2001d), `data/dataset_streaming_template/` and `qwen36_test/`. |
