swm-dmc-mixed-large

Mixed-quality demonstration dataset (split mixed-large) for DeepMind Control Suite environments, repacked from the galilai-group/stable-worldmodel release.

Files

File Description
dmc_mixed-large.tar.zst Zstd-compressed tarball of mixed-quality trajectories; internal paths are dmc/mixed-large/<env>/run.h5

Format

Each run.h5 is an HDF5 file (Blosc-compressed) with datasets:

Key Shape Description
pixels (N, 224, 224, 3) uint8 RGB frames, 224×224
action (N, 6) float32 DMControl action at each step
ep_offset (E,) int Start index of each episode
ep_len (E,) int Length of each episode

Requires hdf5plugin (Blosc filter) to read: import hdf5plugin, h5py.
