Cannot get the split names for the config 'default' of the dataset.

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

python -m venv venv && source venv/bin/activate && pip install -r requirements/qwen36_env.txt
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 ...).
Fix the hardcoded conditioning path. caption_qwen36_pano_perspective_pair.py defines:
```
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.
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).

Run:

cd data/dataset_streaming_template
python stream_process_pinpan_train_syn_captions_only.py
