| # STRIVE MolmoPoint prepared data (gated backup) |
|
|
| This repository keeps copies of prepared MolmoPoint data. With it, a new machine, or this one after `/scratch` is |
| wiped, can skip the SceneSample builds and the InputSample materialization. The contents are derived from the gated |
| `strive-vid` datasets. This repository is gated too: anyone can see this page, but only accounts that an admin of |
| `strive-vid` approves by hand can download the files. Send the access request on this page. The STRIVE repository writes and reads this |
| repository with `makefiles/molmopoint/hub_backup.mk` (code: `strive_datasets/molmopoint/hub_backup.py`). |
|
|
| ## Layout |
|
|
| Each top folder is one materialization date. Inside it, the layout is the same as in the data root (`data/scratch`, |
| a link to `/scratch/ac2538/strive_data`): |
|
|
| ``` |
| <date>/ |
| ├── raw/<repository>/acquisition.json raw repository, pinned revision, and prefix |
| ├── raw/<repository>/catalogs/ mesh-caption catalogs that the scenes record |
| └── molmopoint_prepared/ |
| ├── <source>_v1/scene_samples/ SceneSample parent |
| ├── <source>_v1/input_samples/ collection registry and the children (<label>/<sample_spec_key>/) |
| ├── pack_plans/<preset>/ pack plans built from these children (added when made) |
| └── logs/ build and materialization logs |
| ``` |
|
|
| **The raw scenes are not here.** The videos, masks, and tracks (about 2.7 TB) are the pinned revisions of the |
| `strive-vid` datasets. A child row only points at them, for example at `train/00000/frames/rgb.mp4`, frames 0–96, |
| with the file's SHA-256. `restore` downloads them again at the revision that `raw/<repository>/acquisition.json` |
| records, so each pointer finds the same bytes. |
|
|
| ## Full and compact dates |
|
|
| The raw scenes can be installed in two ways (`acquire --profile`), and each date is built for one of them. Its |
| `raw/<repository>/acquisition.json` says which, and `restore` installs that way. |
|
|
| | Install | What is on disk per scene | Disk for all 36,000 scenes | Dates | |
| | --- | --- | --- | --- | |
| | full (no `profile` in the record) | every file of the scene ZIP; masks as `segmentations/NNN.npy` (512 KiB per frame) | about 2.8 TB | 2026-10-19, 2026-10-27, 2026-10-28 | |
| | compact (`"profile": "compact"`) | only the files that STRIVE reads; masks as one `segmentations.rle.json` (COCO run-length encoding, about 0.1 MB per scene) | 458 GB (test role alone: 38 GB) | 2026-11-02 | |
|
|
| Both download the same scene ZIPs (about 594 GB in all). A compact install writes no `.npy` mask file; while it |
| ran on one node it never held more than 0.7 GB of temporary files, and all 36,000 scenes took about an hour with 8 |
| download threads and 8 encoder processes per source. Every compact file and every decoded mask frame was checked |
| against a full install: all equal. A child reads only the raw files of its own install: use a compact date with |
| compact raw roots, a full date with full raw roots. A compact install needs `pycocotools` (in every lock file of the |
| STRIVE repository). |
|
|
| ```bash |
| # Restore the compact date: parents, children, pack plans, then every raw scene as a compact install (about 458 GB). |
| make -f makefiles/molmopoint/hub_backup.mk restore DATE=2026-11-02 PYTHON="$PYTHON" WORKERS=8 |
| ``` |
|
|
| ## Use |
|
|
| Run from the STRIVE repository root. `HF_HOME` must hold a Hugging Face token with access to this repository (and to |
| the `strive-vid` datasets for a restore). |
|
|
| ```bash |
| # Restore DATE into data/scratch, then download the raw scenes again (2.5 hours for about 2.7 TB on snavely-compute-03). |
| make -f makefiles/molmopoint/hub_backup.mk restore DATE=2026-10-19 PYTHON="$PYTHON" |
| # Back up the prepared data of the three new sources under DATE. |
| make -f makefiles/molmopoint/hub_backup.mk push DATE=2026-10-19 PYTHON="$PYTHON" |
| # Add a pack plan built from the children of DATE. |
| make -f makefiles/molmopoint/hub_backup.mk push-pack-plan DATE=2026-10-19 PRESET=<preset> PYTHON="$PYTHON" |
| ``` |
|
|
| `restore` never overwrites a file: a file that already exists must have the same bytes, else it stops before it |
| moves anything. The one exception is a collection registry (`<source>_v1/input_samples/dataset_info.json`) whose |
| backup version keeps every child entry of the existing one and adds entries: it replaces the existing one after |
| the new children are in place. A rerun after an interruption continues where it stopped. On a host with another GPU type, new |
| packing budgets and pack plans are needed; the parents and children are reused as they are. |
|
|
| The restore depends on the `strive-vid` repositories keeping the recorded revisions. |

Each view is added when it is built. The label `scenes20` holds small development children (the first 20 parents of each role). | `lab-notes/molmopoint/2026-10-22-streaming-baselines/` in the STRIVE repository | |
| | 2026-10-28 | The same sources and revisions as 2026-10-19 | The arm A and arm D children of 2026-10-19 again (same bytes), and the grounded-interaction arm A children `grounded_dense_drop_contacts_grounded_interactions_v1` (label `main`; Breaking-Bad also `scenes20` and the one-row `overfit1`), with the pack plan `ms512_4b_arm_a_gi_b300`. | `lab-notes/molmopoint/2026-10-27-grounded-interactions/` in the STRIVE repository | |
| | 2026-11-02 | The same sources and revisions as 2026-10-19, **compact install** | Every child of the three dates above (38 distinct children), rebuilt from compact raw roots: the same rows except the mask location (`storage: "rle"`, `<scene>/segmentations.rle.json`), and the 17 pack plans of those dates rebuilt for them. Use it with `restore`, which installs compact raw roots. | `lab-notes/molmopoint/2026-11-02-rle-compact-install/` in the STRIVE repository | |
