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).
# 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="$PYTHON" WORKERS=8
Use
Run from the STRIVE repository root. HF_HOME must hold a Hugging Face token with access to this repository (and to
the strive-vid datasets for a restore).
# Restore DATE into data/scratch, then download the raw scenes again (2.5 hours for about 2.7 TB on snavely-compute-03).
make -f makefiles/molmopoint/hub_backup.mk restore DATE=2026-10-19 PYTHON="$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.
