Dataset Viewer

The dataset viewer is not available for this subset.

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

MolmoSpaces RING IL — train-ready datasets

Three train-ready imitation-learning datasets, each packed as an uncompressed tar (payload is already-compressed mp4 + .ckpt, so gzip buys nothing).

archive	uncompressed	contents
`ring_il_v2-76_house6_NO_RANDOMISATION_train_ready.tar`	~23 GB	house-6 ablation, no randomisation
`ring_il_v2-77_house6_RANDOMISATION_train_ready.tar`	~39 GB	house-6 ablation, with randomisation
`ring_il_v66_train_ready.tar.part00/01/02`	~120 GB	BIG_SCALEUP main run (split, see below)

Each archive expands to a directory containing:

train/, val/ — per-worker episode dirs (worker_N/) of raw_*_camera__*.mp4 plus one hdf5_sensors.hdf5 per worker
split_manifest.json — the train/val split (seed, val fraction, episodes per worker)
evals/ — eval summaries, per-house results, rollout videos
train_logs/ — training checkpoints (.ckpt) and wandb run data

The original RAW/ collection directories are not included: their mp4s are byte-duplicates of train/ + val/, so omitting them halves the download.

Download and extract

pip install -U huggingface_hub
hf download chinchinati/molmospaces_ring_il_train_ready \
  --repo-type dataset --local-dir ./molmospaces_ring_il

cd molmospaces_ring_il
tar -xf ring_il_v2-76_house6_NO_RANDOMISATION_train_ready.tar
tar -xf ring_il_v2-77_house6_RANDOMISATION_train_ready.tar

v66 is split across three parts

v66 exceeds the 50 GB per-file limit, so it is stored as three ≤45 GB parts. Concatenate them in order before extracting:

cat ring_il_v66_train_ready.tar.part* > ring_il_v66_train_ready.tar
tar -xf ring_il_v66_train_ready.tar
rm ring_il_v66_train_ready.tar   # optional

Extracting everything needs roughly 180 GB of free disk (plus another 120 GB transiently while reassembling v66).
