feat(policies): add EVO1 policy (#3908)
* feat(policies): add EVO1 policy * fix(evo1): infer batch size after normalizing image dims `_collect_image_batches` read `batch_size = batch[camera_keys[0]].shape[0]` before normalizing per-camera tensors to `(B, C, H, W)`. For an unbatched `(C, H, W)` input (which the function tries to support via the `image.dim() == 3` branch), this picked up the channel count `C` instead of the real batch size, making the subsequent per-sample loop iterate `C` times and indexing go out of bounds. Normalize each camera tensor up-front, then read `batch_size` from the normalized batch dim. Adds `test_collect_image_batches_handles_unbatched_chw` covering the regression. Reported by Copilot review on huggingface/lerobot#3545. * chore(lock): regenerate uv.lock for evo1 extra Adds the `evo1` entry to `[package.metadata.requires-dist]` and the `provides-extras` list so that `uv sync --locked --extra test` (used by fast_tests.yml) no longer reports the lockfile as stale. Generated with `uv 0.8.0` (matching `UV_VERSION` in fast_tests.yml). The non-evo1 marker tweaks are produced by `uv lock` re-resolving the existing dep graph and are not introduced by this PR. * chore(evo1): align with policy contribution guide conventions - Add `src/lerobot/policies/evo1/README.md` symlink into `docs/source/evo1.mdx` to match the in-tree README convention (mirroring the EO-1 layout). - Convert `transformers` import in `internvl3_embedder.py` to the standard `TYPE_CHECKING + _transformers_available` two-step gating used by other optional-backbone policies (e.g. diffusion). The previous lazy-in-`__init__` import was functionally equivalent for runtime gating but didn't expose the real symbols to type checkers. - Add `lerobot[evo1]` to the `all` extra in `pyproject.toml` so `pip install 'lerobot[all]'` keeps installing every optional policy. Per the guidance in https://moon-ci-docs.huggingface.co/docs/lerobot/pr_3534/en/contributing_a_policy. * fix(evo1): finalize policy guide alignment * docs(evo1): format results table * Fix EVO1 LIBERO rollout processors * Fix EVO1 LIBERO eval action postprocessing * Fix eval action conversion for bf16 policies * fix(evo1): move LIBERO padding into policy processors * refactor(evo1): use native HF InternVL3-1B-hf, drop trust_remote_code - Switch from OpenGVLab/InternVL3-1B (requires trust_remote_code=True) to OpenGVLab/InternVL3-1B-hf (native transformers implementation). - Replace manual _extract_feature + _prepare_and_fuse_embeddings with a single model.forward() call — verified bit-for-bit identical output. - Remove ~170 lines of manual ViT/pixel-shuffle/projection logic. - Symlink README.md to docs/source/ following repo convention. Weights are byte-identical between both model variants; only the module naming differs. All 12 existing unit tests pass. Local training (10 steps) on maximellerbach/omx_pickandplace confirmed working. * refactor(policy): evo1 GPU-batched preprocessing + vectorized attention masking + remove dead code * fix(style): pre-commit oops * chore(evo1): delete added test + reduce diff * refactor(policies): use config for evo1 + local imports * refactor(policies): multiple improvements * chore: update docs + remove legacy codepaths * feat(policies): implement RTC to EVO1 --------- Co-authored-by: javadcc_mac <javadcc1@sjtu.edu.cn> Co-authored-by: Yiming Wang <145452074+JAVAdcc@users.noreply.github.com> Co-authored-by: Martino Russi <nopyeps@gmail.com> |

feat(policies): add Gr00t N1.7 policy (#3922)
* Add GR00T N1.7 support
Add GR00T N1.7 policy configuration, checkpoint compatibility, processor parity, LIBERO documentation, and focused tests.
Co-authored-by: Ryan Halabi <ryhalabi@nvidia.com>
* Move Groot processor compatibility into Groot loader
* Restore GR00T Flash Attention install guidance
* Allow Groot fake RTC chunk prefetch
* Fix GR00T N1.7 RTC action decoding
* Trim GR00T N1.7 RTC chunks to valid horizon
* Ignore padded GR00T N1.7 RTC prefix rows
* removed n1.5 dependency
* removed remaining N1.5 traces
* groot: auto-enable LIBERO gripper action transform for libero_sim
GR00T N1.7 emits gripper in [0,1] but LIBERO expects [-1,1]. The decode
transform existed but was never auto-enabled for embodiment_tag=libero_sim,
so the policy scored 0% on LIBERO eval. Auto-set it in __post_init__ (still
overridable). LIBERO Spatial eval: 0% -> 98%.
* Reconnect GR00T relative action processors
* groot: remove dead N1.5 code (eagle2_hg_model, flow_matching_action_head, action_encoder)
N1.7 backbone is nvidia/Cosmos-Reason2-2B via Qwen3VLForConditionalGeneration,
not Eagle2 — eagle2_hg_model/ had zero refs outside its own dir.
GR00TN17ActionHead (groot_n1_7.py) re-implements MultiEmbodimentActionEncoder +
CategorySpecificLinear + swish + SinusoidalPositionalEncoding locally, so
flow_matching_action_head.py (N1.5 FlowmatchingActionHead) and its sole
dependency action_encoder.py are dead. Verified: no src/ or tests/ reference.
Removed (~2037 LOC):
- eagle2_hg_model/ (4 files, ~1575 LOC)
- action_head/flow_matching_action_head.py (408 LOC)
- action_head/action_encoder.py (54 LOC)
cross_attention_dit.py KEPT (DiT/AlternateVLDiT/SelfAttentionTransformer live in N1.7).
* groot: reuse lerobot get_device_from_parameters instead of inline lookup
modeling_groot.py duplicated next(self.parameters()).device twice. LeRobot
ships get_device_from_parameters in policies/utils.py (used by diffusion,
vqbet, tdmpc, gaussian_actor). Reuse it for consistency with the framework.
* groot: fix stale Eagle VLM docstring in processor (N1.7 uses Qwen3-VL backbone)
Addresses checker nit: processor_groot.py docstring still described the N1.5
Eagle VLM path with eagle_content/eagle_* keys that no longer exist in the code.
* test(groot): add N1.7 original-vs-LeRobot output parity test
Verifies the LeRobot GR00T N1.7 integration produces equivalent raw
action_pred to NVIDIA Isaac-GR00T for the same checkpoint, inputs, seed,
precision (fp32) and attention kernel (SDPA): max|diff|=8.9e-7 on the
libero_sim embodiment (GR00T-N1.7-LIBERO/libero_10).
The two impls pin incompatible transformers majors (orig 4.57.3 vs
LeRobot 5.x) and cannot share a process, so the original outputs + exact
collated inputs are produced out-of-process and loaded from an .npz. The
test skips on CI / when the checkpoint or artifact are absent.
* test(groot): parametrize N1.7 parity across all checkpoint embodiments
Generalize the original-vs-LeRobot N1.7 output-parity test from a single
libero_sim case to every embodiment tag in the checkpoint (libero_sim, oxe_droid,
real_g1, the real_r1_pro_sharpa family, and the xdof family). Inputs are built
generically from checkpoint metadata; the test discovers per-tag .npz artifacts
and runs one parametrized case each, loading the LeRobot model once via a fixture.
All 9 embodiments match the original to fp32 epsilon (max|diff| < 3e-6), confirming
the integration is correct across the model's full embodiment space and not overfit
to libero_sim.
* test(groot): self-contained parity test + in-repo producer + docs
- Rename test_groot_n1_7_vs_original.py -> test_groot_vs_original.py
- Make the test self-contained: producer script (dump_original_n1_7.py) now lives
next to the test; default artifact dir is repo-relative
(tests/policies/groot/artifacts/), overridable via GROOT_N1_7_PARITY_DIR. The
test only reads artifacts and skips if absent -- it never creates external dirs.
- Heavy .npz artifacts (~6-9MB each) are gitignored and regenerated by the producer;
never committed.
- Drop the verbose 'MULTIPLE EMBODIMENTS' docstring block (kept a one-line note).
- Document the parity procedure in the groot policy README (docs/source/policy_groot_README.md).
- Rename test fn test_groot_n1_7_get_action_parity -> test_groot_get_action_parity.
9/9 embodiments still pass (max|diff| < 3e-6, fp32 eps).
* docs(groot): drop WHY TWO ENVIRONMENTS block from parity test docstring
* test(groot): move parity producer into utils/ package
Mirror the tests/policies/pi0_pi05/utils convention: move dump_original_n1_7.py into
a tests/policies/groot/utils/ package (with __init__.py) and update all path
references in the test docstring/skip-message and the policy README.
* test(groot): adopt test_groot_lerobot for GR00T N1.7, drop N1.5
The test loaded MODEL_PATH='aractingi/bimanual-handover-groot-10k', an N1.5
checkpoint (config base_model_path=nvidia/GR00T-N1.5-3B, no model_version). On
load, model_version defaults to n1.7 while the base path infers n1.5, so the
version-consistency guard in GrootConfig.__post_init__ raised ValueError and both
test_lerobot_groot_inference and test_lerobot_groot_forward_pass failed. N1.5 is no
longer a supported model_version.
Adopt the test for N1.7:
- MODEL_PATH -> nvidia/GR00T-N1.7-3B (root-level sharded safetensors; loads via
GrootPolicy.from_pretrained as a base N1.7 model).
- Embodiment tag 'gr1' (N1.5) -> 'gr1_unified' (valid N1.7 tag from the checkpoint
embodiment_id.json), via a single EMBODIMENT_TAG constant.
- DUMMY_ACTION_HORIZON 16 -> 40 to match N1.7's native action-chunk size.
- Docstrings/labels updated to 'GR00T N1.7'.
Both tests run and pass on CUDA; full tests/policies/groot/ suite is
73 passed / 0 failed / 0 skipped.
* docs(groot): document the N1.5 removal and the N1.7 parity test
- groot.mdx: breaking-change warning and migration path (pin lerobot==0.5.1 to
keep N1.5, or move to N1.7); the dead `huggingface-cli download` is replaced
with `hf download`.
- policy_groot_README.md: N1.5 removal note, updated paper / model-card links,
and the two-comparison (model parity + preprocessor parity) description of
the original-vs-LeRobot test, including the raw-observation artifacts and
recorded seed.
* fix(groot): N1.7 backbone loading and DiT parameter-count logging
- select_layer default tracks the N1.7-3B checkpoint value (16); real
checkpoint loads still override it from config.json.
- get_backbone_cls recognizes Cosmos-Reason2 / Qwen3-VL backbones by name and
warns (instead of silently assuming) when an unrecognized backbone is loaded
only on the strength of backbone_model_type='qwen'.
- 'revision' pins the GR00T checkpoint repo only and is no longer forwarded
into the unrelated backbone repo load; pin the backbone via
transformers_loading_kwargs instead.
- DiT / SelfAttentionTransformer parameter counts go through logging.debug
instead of print().
* fix(groot): N1.7 config defaults, N1.5 rejection, and processor/model runtime fixes
Covers the GR00T N1.7 source trio (configuration, processor, model wrapper).
Config:
- GrootConfig defaults are the N1.7 values; explicitly passed legacy N1.5-era
values (chunk_size=50, max_state_dim=64, ...) are remapped with a warning
instead of silently.
- action_decode_transform gains an 'auto' sentinel so an explicit 'none'
opt-out wins over the libero_sim default and survives save/load round-trips.
- action_delta_indices is cached on the inputs that determine it.
- Legacy N1.5 checkpoints/configs (tokenizer_assets_repo, model_type/
architectures/eagle backbone markers) are rejected with a single clear
error pointing to lerobot==0.5.1.
Processor:
- GrootN17ActionDecodeStep handles the 2-D (B, D) actions delivered by sync
select_action (relative eef/non-eef decode in eval/record flows).
- Postprocessor falls back to dataset stats when a raw checkpoint lacks the
configured embodiment tag; raw-state cache is per-instance, not
process-global; caller overrides (device, rename_map) are honored on the
raw-checkpoint branch.
- Camera/modality-key mismatches warn (including the zero-match fallback);
deprecated Qwen2VLImageProcessorFast replaced with Qwen2VLImageProcessor;
removed N1.5 processor steps are stubbed to raise the removal guidance and
the action-unpack step is re-registered as _v2.
Model:
- Flash-attention probe is diagnostic-only; forward raises on a missing loss;
print() replaced with logging; N1.5 base-path mismatch includes the
removal guidance.
* fix(groot): skip normalization overrides for training
* fix(groot): GPU/tensor N1.7 image preprocessing + resize to trained resolution
GR00T training was dataloader-bound (0->100->0 GPU-utilization sawtooth).
GrootN17VLMEncodeStep ran the Qwen3-VL image processor per frame on PIL images
on the single CPU main-loop thread, and that cost is timed inside dataloading_s
(preprocessor(batch) runs in the main process, not the dataloader workers), so
adding workers cannot hide it.
- Feed the torchvision-backed Qwen3-VL processor (C,H,W) uint8 tensors instead
of a per-frame Image.fromarray PIL roundtrip, and run resize/normalize/patchify
on config.device (GPU) when available. Bit-identical on CPU when no resize is
configured; with a resize only the PIL->torchvision bicubic backend differs
(<2/255 per pixel). The use_albumentations path stays PIL/cv2; reload on a box
without the saved device falls back to CPU.
- Default image_target_size/crop to the N1.7 backbone's training geometry
(256x256 / 230x230) when a checkpoint ships no image sizing (checkpoint_assets
is None, e.g. finetuning nvidia/GR00T-N1.7-3B via repo-id with a new
embodiment). Previously image_target_size=None disabled the resize, so
full-resolution frames were patchified into ~4.7x more vision tokens than the
model was trained on -- inflating dataloading_s (patchify) and update_s (VLM
sequence) and skewing the input distribution. Checkpoints that pin their own
sizing are honored; the default constants are shared with GR00T_N1_7_DEFAULTS.
Net: preprocessing leaves the CPU critical path and the VLM sees the resolution
it was trained on -- faster training/inference and a correct train/serve
distribution. Affects inference too (shared preprocessor); existing checkpoints
still load (backward compatible) but must be retrained to gain the benefits.
* refactor(groot): N1.7 style cleanup (utils, imports, flash-attn, config)
Mechanical refactor of the GR00T N1.7 policy to match the repo's architecture and
style standards. No change to policy algorithm/numerics; only UX/CLI and packaging
changes. Tests are intentionally left untouched (out of scope) and need updating
for the removed `model_version` field.
Cleanup & consolidation:
- Add `groot/utils.py` holding the pure, side-effect-free helpers (JSON I/O, value
coercion, stat flattening, rot6d/SE3 math, language/batch prep) shared by the
config and processor layers.
- Remove dead code: the unused `resolve_groot_n1_7_backbone_model` cache-resolver
cluster, `GR00TN17Config.to_filtered_dict/json`, and the `_copy_default` wrapper.
Imports & execution guards:
- Hoist nested imports to module top; relative imports within the package, absolute
for external modules. The version-gated Qwen3-VL classes import under the single
`_transformers_available` guard (transformers is pinned >=5.4, which ships them).
- No import-time side effects: `_register_with_transformers()` now runs in
`GR00TN17.__init__` (idempotent via `register(exist_ok=True)`), and the N1.5 step
stubs register lazily before pipeline deserialization (idempotent via the
registry, no run-once globals).
- Gate optional deps at the point of use with `require_package(..., extra="groot")`.
Dependencies & docs:
- Drop `flash-attn` (and its build-only dep `ninja`) from the `groot` extra; default
to SDPA (numerically equivalent) with opt-in via `--policy.use_flash_attention`.
Un-comment `lerobot[groot]` in the `all` extra and regenerate `uv.lock`.
- Rewrite the `groot.mdx` install section: flash-attn is a purely optional,
user-managed optimization that LeRobot neither installs nor requires.
Config & CLI:
- Surface previously-frozen knobs on `GrootConfig` (plumbed into `GR00TN17Config`;
no-ops at their defaults): inference — `num_inference_timesteps`, `rtc_ramp_rate`,
`use_flash_attention`; fine-tuning — `tune_top_llm_layers` (partial-LLM tuning)
and `tune_vlln` (previously hardwired to True).
- Convert the single-valued `model_version` and `n1_7_backbone_model` fields to
internal constants.
- Keep `base_model_path`: it is NOT equivalent to `pretrained_path` (raw NVIDIA
checkpoints have no LeRobot `type` field and load only via `base_model_path`) and
is genuinely user-tunable.
- Keep the deprecated Isaac-GR00T/N1.5 fields (and the dead LoRA fields) as a
back-compat block so a v0.5.1 N1.5 `config.json` still parses under draccus and is
rejected with the friendly N1.5 removal message instead of an opaque decode error.

LingBot-VA: video-action world model (#3731)
* feat(policies): add LingBot-VA autoregressive video-action world model Port the LingBot-VA policy (Wan2.2 dual-stream video+action world model) into LeRobot, following the EO-1 / VLA-JEPA conventions. Covers inference, checkpoint conversion, and predicted-video saving (training is deferred to a follow-up PR). - Vendored Wan transformer/attention/flex/VAE/scheduler modules (key names preserved for near-identity conversion); torch SDPA default, flashattn/flex lazy-guarded. - LingBotVAConfig (registered "lingbot_va") + processor with fixed-quantile action unnormalization; full dual-stream sampling loop with CFG, two flow-matching schedulers and KV cache, mapped onto select_action with observed-keyframe feedback. - convert_lingbot_va_checkpoints.py (libero/robotwin variants): bundles the ~5B transformer, lazy-pulls the frozen VAE+UMT5 from the source repo. - Predicted-video plumbing in lerobot_eval (predicted_frames_callback; opt-in via --policy.save_predicted_video) and ConstantWithWarmupSchedulerConfig. - pyproject: widen diffusers-dep to <0.37, add lingbot_va + imageio-dep extras, add lingbot_va and (missing) eo1 to `all`. - Factory + policies/__init__ wiring, docs page + toctree, and tests. Note: the LIBERO success-rate correctness gate must be validated on a CUDA GPU with the converted checkpoint. * feat(lingbot_va): RoboTwin eef-pose eval, single-file model, Hub checkpoints Make the LingBot-VA port runnable on both LIBERO and RoboTwin and clean up the package to LeRobot conventions. - Consolidate all vendored Wan2.2 model code (transformer, attention, VAE helpers, flow-matching scheduler, grid utils, flex-attention) into a single modeling_lingbot_va.py; remove the separate wan_*/schedulers modules. - Move the fixed action (un)normalization quantiles out of the config and into the post-processor (LIBERO 7-DoF + RoboTwin 16-d eef); remove the conversion script in favour of ready-to-use LeRobot-format checkpoints on the Hub. - Fixes found via on-sim validation: undo LIBERO's 180-degree image flip (image_hflip), encode obs as a multi-frame streaming-VAE clip, reset the streaming VAE cache between episodes, run the transformer in config.dtype, lazy-load frozen VAE/UMT5 by subfolder with the text encoder on CPU. - RoboTwin: add an end-effector-pose action mode to RoboTwinEnv (16-d per-arm xyz+quat+gripper deltas composed onto the initial eef pose, executed via CuRobo IK) and the robotwin_tshape latent layout (full-res head + half-res wrists via a second streaming VAE) with the upstream RoboTwin action quantiles + camera mapping. - Predicted-video saving works for both benchmarks; docs + tests updated. * feat(lingbot_va): implement training / fine-tuning (flow-matching loss) - Implement LingBotVAPolicy.forward(): dual-stream flow-matching training loss (latent + action, timestep-weighted, action-masked) ported from upstream train.py; VAE-encodes camera clips, UMT5-encodes the task, noises both streams, runs the block-causal flex-attention training pass (forward_train). - training_loss_from_streams() core + _build_training_streams() data prep (action scatter into the 30-d space, multi-frame VAE encode incl. robotwin_tshape). - get_optim_params returns only trainable transformer params (LoRA/PEFT friendly); VAE/UMT5 stay frozen. Training needs attn_mode='flex'. - Add a tiny-config single-training-step test (forward->loss->backward->AdamW) and a Training/fine-tuning section in the docs. * fix(lingbot_va): CI quality gate + fast-test collection - Add tests/policies/lingbot_va/__init__.py so the test files don't clash by basename with tests/policies/vla_jepa/* under pytest's default import mode (fast-test collection error). - Fix vendored typos flagged by the typos hook (pach_scale->patch_scale, total_tolen-> total_token_len, stablized->stabilized) and a mypy union-attr in RoboTwinEnv._read_eef_pose. - Apply Prettier formatting to docs/source/lingbot_va.mdx. * docs(lingbot_va): document EEF action-channel schema + camera order * Update lingbot_va.mdx Signed-off-by: Pepijn <138571049+pkooij@users.noreply.github.com> * Update pyproject.toml Signed-off-by: Pepijn <138571049+pkooij@users.noreply.github.com> * Update pyproject.toml Signed-off-by: Pepijn <138571049+pkooij@users.noreply.github.com> * refactor(lingbot_va): drop hardcoded action quantiles; source from checkpoint The LIBERO/RoboTwin action (un)normalization quantiles were hardcoded as module constants in processor_lingbot_va.py. They are already serialized into each checkpoint's policy_postprocessor.json (via LingBotVAActionUnnormalizeStep.get_config) and restored on load by PolicyProcessorPipeline.from_pretrained, so the constants are dead at eval/load time for the released checkpoints (verified: libero_long/robotwin/base all carry their quantiles on the Hub). - Remove LIBERO_ACTION_Q01/Q99, ROBOTWIN_ACTION_Q01/Q99 and _default_action_quantiles. - make_lingbot_va_pre_post_processors now defaults a fresh (unconverted) build to a neutral [-1, 1] mapping (identity rescale); real per-benchmark stats come from the saved checkpoint (or postprocessor_overrides), analogous to dataset-stats normalization. - Update the config doc comment to point at the checkpoint as the source of truth. - Tests: replace the LIBERO-default assertion with a neutral-default check, and add a save_pretrained/from_pretrained round-trip guard for the quantile serialization. * docs(lingbot_va): trim verbose comments - configuration_lingbot_va.py: condense multi-line field comments to one-liners (keep the ── section headers). - processor_lingbot_va.py: shorten the action-quantile explanation block. - modeling_lingbot_va.py: drop the bare "# ----" separator rules, keeping the one-line section headers. No code changes. * docs(lingbot_va): trim provenance comments; default wan path to base repo - configuration_lingbot_va.py: drop the "──" decorations and the "(from transformer/config.json)" note; default wan_pretrained_path to robbyant/lingbot-va-base (has the frozen vae/text_encoder/tokenizer subfolders). - modeling_lingbot_va.py: remove the vendored-code banner and the "(upstream wan_va/...)" section-header provenance/dash decorations; condense the transformer-dtype comment to one line. No code changes. * refactor(lingbot_va): use built-in UnnormalizerProcessorStep for actions Replace the bespoke LingBotVAActionUnnormalizeStep with the standard UnnormalizerProcessorStep in QUANTILES mode, which computes the identical (action + 1) / 2 * (q99 - q01) + q01 mapping. The per-channel q01/q99 are stored as the step's saved state (a safetensors file) and restored on load; a fresh build has no action stats so the step is an identity passthrough. The 3 Hub checkpoints (lerobot/lingbot_va_{libero_long,robotwin,base}) have been re-uploaded with the new post-processor (policy_postprocessor.json + *_unnormalizer_processor.safetensors); reloading from the Hub round-trips q01/q99. - processor_lingbot_va.py: drop the custom step + registry; build the post-processor with UnnormalizerProcessorStep (explicit ACTION->QUANTILES norm_map so the preprocessor / training path is unchanged). - tests: assert the built-in step is used, identity-when-no-stats, correct quantile unnormalization, and a save_pretrained/from_pretrained stats round-trip. * docs(lingbot_va): point checkpoint paths at the lerobot org The LeRobot-format checkpoints moved from pepijn223/* to lerobot/* (libero_long, robotwin, base). Update the eval/train --policy.path examples accordingly. * docs(lingbot_va): condense processor normalization comments * fix(lingbot-va): align RoboTwin evaluation (#3784) Thank you for the RoboTwin fix, and alignment! * applying fixes * updating uv lock and linting * adjusting test to match expected values * cleaning up deps * cleaning up top level imports, styling, and deps guards * cleanup * moving wan utils and loading utils to `utils.py` * removing ftfy by replicating the prompt_clean function without it (we don't expect to have weird chars given in the prompt anyway) * removing unused function * guarding for scipy dep, renaming test to avoid collision * adding back accelerate for peak memory usage optim + justifying robotwin description dep --------- Signed-off-by: Pepijn <138571049+pkooij@users.noreply.github.com> Co-authored-by: pepijn223 <pepijn223@hf.co> Co-authored-by: Gangwei XU <gwxu@hust.edu.cn> Co-authored-by: Maxime Ellerbach <maxime.ellerbach@huggingface.co> |

refactor(runtime): template-method adapter base + policy registry; rename CLI
Make the policy adapter architecturally clean and set up a single general entry point for any language-conditioned policy. Adapter architecture (Template Method): - New lerobot/runtime/adapter.py: BaseLanguageAdapter owns the generic control loop (throttle → generate → gibberish/empty reject → subtask→memory cascade → diagnostics) and plan_from_text/handle_interjection. A policy supplies only select_action + generate_text + build_messages. The subtask→memory cascade is an overridable hook (_regenerate_context). - GenerationConfig (typed, constructor-time) replaces config smuggled through RuntimeState.extra (temperature/top_p/min_new_tokens/chunks_per_regen). - LanguageDiagnostics (typed, keyed by kind) replaces ~8 loose state.extra counter keys; the panel reads it via the adapter. - looks_like_gibberish + split_plan_and_say move to runtime (generic). Contract: - LanguageConditionedPolicyAdapter protocol now states the true contract (select_action, update_language_state, handle_interjection); the runtime drops both getattr fallbacks. - PI052PolicyAdapter shrinks to just its primitives (132 → ~half). General entry point: - lerobot/runtime/registry.py maps policy type → adapter (lazy import). - run() resolves the adapter from the registry by policy type and defaults the panel label to it, so one CLI serves every policy. - Rename lerobot-pi052-runtime → lerobot-language-runtime (general script); a new policy just registers its adapter, no new script. Tests: new tests/runtime/test_adapter.py covers throttle/reject/cascade/ interjection; adapter + runtime + CLI-smoke tests updated for the new shape.

refactor(runtime): make language runtime policy-agnostic; drop VQA viz
Set up the runtime so a second language-conditioned policy reuses the CLI/REPL/UI instead of copying pi052's. The tick loop, REPL, panel, and interactive CLI are now policy-independent in lerobot/runtime/; a policy plugs in only a LanguageConditionedPolicyAdapter. - Move repl.py, ui.py, and runtime_cli.py (-> cli.py) from pi052/inference/ into lerobot/runtime/. Generalize labels/titles (panel_label param, [runtime] prefixes). - lerobot.runtime.cli.run(argv, *, adapter_factory, panel_label, prog) is the shared entry; policy loading already dispatches generically via the factory on cfg.type. - lerobot-pi052-runtime is now a thin entry (scripts/lerobot_pi052_runtime.py) that passes PI052PolicyAdapter into run(). pi052/inference/ keeps only the adapter. - Drop PI052Runtime back-compat wrapper (no consumers). - Drop VQA visualization: delete inference/vqa.py + test_pi052_vqa_loc.py, remove answer_vqa/VQAResult from the Protocol + adapter, and the /question command + overlay paths from the CLI/REPL.

refactor(pi052): trim PR — remove say tool, debug gates, dead code; move runtime
Cleanup pass over the language-support PR to cut LOC and scope creep. Removals: - SayTool + tools/ package (registry, Tool protocol, [tools] extra) and the runtime's tool-dispatch path. Kept <say> training supervision and inference stripping so speech-annotated datasets still train. - WeightedEpisodeAwareSampler + VQA oversampling wiring (_build_vqa_oversample_weights, vqa_target_fraction) — training uses plain EpisodeAwareSampler again. - Debug env-gates PI052_DEBUG_TENSORS, PI052_SUBTASK_USE_TASK, EVAL_TASK_OVERRIDE. - Dead code: broken _tp._DUMP_BUDGET block, unused imports (copy/Tensor, RevisionNotFoundError, LeRobotDataset, os), messages_for_vqa, steps.py shim (modeling imports pi052_adapter directly), duplicated _emit, builtins.type[T]. Moves: - Policy-agnostic runtime -> src/lerobot/runtime/ (LanguageConditionedRuntime + adapter Protocol + state); pi052 keeps only its adapter + CLI. Tests -> tests/runtime/. Other: - Compacted verbose AI-authored comments/docstrings across pi052 (kept the hard-won DDP / barrier-timeout / reduce-max / VQA-routing notes). - Relocated LM-head prediction debug helper to pi052/debug_utils.py. - Fixed test_render_messages: assert task-fallback render (current behavior) instead of the stale no-op expectation.

fix(depth unit): adding input depth unit storage in the dataset metadata (#3899)
* fix(depth unit): storing raw depth units in the dataset metadata for correct depth statistics and depth raw frames handling. The unit is stored as a string ("m","mm") under "depth_unit" at the same level as "is_depth_map". Unit is inferred from the depth frame type.

feat(visualization): add foxglove support (#3902)
* Add Foxglove display mode for teleoperate
Add a --display_mode flag (rerun|foxglove) to lerobot-teleoperate. When set
to foxglove, stream observations/actions over a Foxglove WebSocket server:
images as RawImage/CompressedImage, scalars as typed JSON channels with
schemas generated from the feature names (sanitized so paths don't need
quoting). Adds a `foxglove` extra.
* Add Foxglove display mode to lerobot-record
Wire the --display_mode flag (rerun|foxglove) into lerobot-record, matching
lerobot-teleoperate: route init/log through the backend-agnostic dispatchers
and stop the visualization backend on exit.
* update foxglove-sdk to 0.25.1
* Use static lerobot.Scalars schema for Foxglove state topics
Replace the per-topic JSON schema derived from feature names with a single
static lerobot.Scalars schema: a scalars array of {label, value} objects. The
same schema fits any robot regardless of which observation/action features it
reports, and the label field lets Foxglove name each series automatically so
one filtered path plots every feature.
* add foxglove option to dataset viz
* Make Foxglove dataset playback loop the sole frame emitter
Address review: the listener no longer emits frames, it only mutates
playback state and queues a one-shot seek index that the playback loop
services. The loop is now the only caller of emit_frame, so concurrent
random access into the on-disk dataset / video decoder never overlaps.
Also remove the dead server_holder and tighten the _foxglove_safe_name
docstring to state what it does and why.
* Label Foxglove dataset scalars with feature dimension names
Use the dataset's per-dimension feature names (e.g. joint names) as the
Foxglove series labels for /observation/state and /action/state instead
of bare indices. LeRobot stores `names` inconsistently (flat list,
{category: [...]}, or {name: index}), so _feature_dim_names handles each
and falls back to indices on any unknown format or length mismatch.
* Make Foxglove server host bindable and refactor topic/channel handling
Pass display_ip through as the Foxglove WebSocket bind host (127.0.0.1
for local only, 0.0.0.0 for all interfaces) instead of always binding
locally. In lerobot-dataset-viz, fold the separate --port into --web-port
so one flag covers both the Rerun web viewer and the Foxglove server port.
Add a _foxglove_topic() helper and thread a per-topic channel cache
through the log helpers so dataset playback stays self-contained instead
of mutating the module-global cache. Promote SUCCESS to constants.py.
* feat(viz): add support for foxglove in rollout + add to viz tag
* fix(docs): remove misleading installation note
* fix(visualization): no duplicated prefix, consolidated norm + warnings log
* chore(viz): minor improvements
* refactor(viz): split files + autoplay + updated docs + added minimal tests
* fix(viz): right tags + warning
* feat(deprecated ws-port): removing rerun's depreacted ws-port parameter in dataset visualization
* chore(web ports): adding global variables for default foxglove/rerun web ports
* feat(depth): adding depth support to foxglove visualizer. Because of foxglove limitations (min and max values on RawImage cannot be set from the SDK), depth is normalized between [0,1] when a depth range is provided.
* fix(rerun depth range): making rerun depth range computation safe against missing stats
* chore(foxglove depth): make it simple, and make it work.
* fix(scaling): fixing depth frames scaling

feat(train): run training remotely on HF Jobs via --job.target (#3856)
* feat(train): add JobConfig group, save_checkpoint_to_hub flag, Hub checkpoint helper
Introduce a JobConfig draccus group on TrainPipelineConfig (--job.target/image/
timeout/detach/tags) whose is_remote property gates remote dispatch, plus a
save_checkpoint_to_hub flag and validation. Add push_checkpoint_to_hub(), which
uploads a saved checkpoint directory to the model repo under checkpoints/<step>/
and creates the repo idempotently (private propagates from policy.private).
* feat(train): run training remotely on HF Jobs via --job.target
When --job.target names a GPU flavor, train() dispatches to lerobot.jobs.submit_to_hf
instead of training locally: it authenticates, ensures the dataset is on the Hub
(pushing a local-only one privately), serializes a pod-compatible train_config.json
(strips client-only fields, points at the model repo), submits via HfApi.run_job
with HF_TOKEN/WANDB_API_KEY secrets, then streams logs and finishes when the model
is pushed. Wires push_checkpoint_to_hub into the training loop behind
save_checkpoint_to_hub, and tags jobs/datasets/model with 'lerobot' + --job.tags.
* docs(train): document remote training on HF Jobs
* test(train): skip remote-dispatch tests without the dataset extra
The module imports lerobot.scripts.lerobot_train, which eagerly pulls in
lerobot.datasets (dataset extra). The base fast-test CI tier runs without
that extra, so collection failed there. Guard with pytest.importorskip,
matching the existing tests/scripts dataset-extra tests.
* refactor(jobs): hoist huggingface_hub imports to module level in hf.py
huggingface_hub is a core dependency, so the per-function dynamic imports
had no lazy-loading rationale. Move them to a single module-level import
and update test monkeypatch targets to lerobot.jobs.hf.* accordingly.
* refactor(jobs): build remote config dict via cfg.to_dict()
TrainPipelineConfig.to_dict() already returns the canonical draccus
encoding, so the StringIO + draccus.dump + json.loads round-trip was
redundant. Use it directly and drop the now-unused io/draccus imports.
* refactor(train): use module-level HfApi import in push_checkpoint_to_hub
huggingface_hub is a core dependency; the in-function import was
unnecessary. Move HfApi to a module-level import and point the test
monkeypatches at lerobot.common.train_utils.HfApi.
* refactor(configs): export JobConfig from the configs package
Re-export JobConfig in lerobot/configs/__init__.py so external callers
import it as `from lerobot.configs import JobConfig`, matching the other
config classes. Adapt the train script and test imports.
* refactor(jobs): check dataset presence with api.repo_exists
Replace the dataset_info try/except RepositoryNotFoundError dance with a
direct api.repo_exists(repo_id, repo_type="dataset") call, dropping the
httpx/RepositoryNotFoundError test scaffolding.
* chore(jobs): annotate ensure_dataset_available api param as HfApi
Add the missing HfApi type hint via a TYPE_CHECKING import.
* refactor(jobs): use HF_LEROBOT_HOME constant for the local cache root
Resolve the local dataset cache via lerobot.utils.constants.HF_LEROBOT_HOME
instead of re-reading the env var by hand, dropping the os/Path imports.
Tests now patch the imported constant and assert on a stable message
substring (the previous "neither" match only passed by accident, matching
the test name embedded in the pytest tmp_path).
* chore(jobs): guard LeRobotDataset import with require_package
Surface a clear "install lerobot[dataset]" error if the datasets extra
is missing, instead of a raw ImportError, before pushing a local dataset.
* docs(configs): clarify the is_remote_target/is_remote split
Add a comment explaining why JobConfig keeps both the staticmethod (tests
a raw target string from argv before a config exists) and the property
(accessor for an existing config instance).
* docs(train): note how to pin a pushed model version for inference
Document --policy.pretrained_revision alongside --policy.path so a
specific Hub-pushed checkpoint (once --save_checkpoint_to_hub has
committed several) can be selected for inference.
* test(jobs): skip dataset import guard in base-deps test
The fast test env installs base deps only, so require_package('datasets')
raised ImportError before the mocked lerobot.datasets import was reached.
Monkeypatch the guard to a no-op so the unit test exercises the upload logic.
* fix(jobs): address claude review findings on remote training
Resolve the claude[bot] review on #3856:
- Reject reward-model training under --job.target with a clear error instead
of crashing on a None policy inside build_remote_config_file.
- Support --policy.path remote runs: validate() no longer requires repo_id for
remote runs (it is auto-generated in submit_to_hf), and repo_id/push_to_hub
are now set after validate() resolves the policy.
- Narrow the bare `except Exception` in _tail_logs/_poll_until_done to
(OSError, httpx.HTTPError) so programming errors surface instead of being
silently retried or counted as job failures.
- Install the SIGINT detach handler only on the main thread.
- Generate model repo timestamps in UTC.
* docs(jobs): document the model-pushed marker contract and orphaned repos
Follow-up to the claude[bot] review on #3856 (non-blocking observations):
- Cross-reference the "Model pushed to <url>" log line between its producer
(PreTrainedPolicy.push_model_to_hub) and the remote-run consumer in
submit_to_hf, noting the contract is an early-finish optimization that
falls back to status polling if it drifts.
- Note in the HF Jobs guide that a failed remote run leaves its model repo
on the Hub (it is not auto-deleted) and how to remove it.
* feat(train): tag each pushed checkpoint with its step
Address review feedback on #3856: pushing a checkpoint to the Hub now
also creates a tag named after the checkpoint step, so a checkpoint can
be recovered with --policy.pretrained_revision=<step> instead of having
to look up its commit sha.
* fix(jobs): hoist ensure_dataset_available to a module-level import
Addresses Caroline's review comment on PR #3856: the local import of
ensure_dataset_available inside submit_to_hf was vestigial. dataset.py
does not import hf.py, so there is no circular-import risk and no extra
load cost (its heavy deps stay lazy), so make it a top-level import.
* refactor(configs): untangle config_path/resume resolution in validate()
Split the re-parse HACK block in TrainPipelineConfig.validate() into focused
helpers (_resolve_pretrained_from_cli, _resolve_resume_checkpoint) that handle
the policy path, reward-model path, and resume config_path as separate,
readable units. Behavior-preserving.
* feat(train): resume training from a Hub checkpoint
Allow --config_path to be a Hub repo id when resuming, not only a local path.
The latest checkpoint under checkpoints/<step>/ is downloaded into a fresh local
run dir and resumed from there (optimizer, scheduler, RNG and data order
restored as for a local resume). TrainPipelineConfig.from_pretrained falls back
to the latest checkpoint's train_config.json when a repo has no root config
(an interrupted run that only pushed checkpoints). The download is skipped when
dispatching remotely so the executor (local machine or HF Jobs pod) performs it.
- add find_latest_hub_checkpoint (utils/hub) and resolve_resume_checkpoint
(common/train_utils), the symmetric download counterpart to
push_checkpoint_to_hub
- unit tests for both helpers and the from_pretrained fallback
* feat(jobs): resume a run on HF Jobs from a checkpoint
When --resume is set with a remote --job.target, submit_to_hf resumes from the
checkpoint repo instead of staging a fresh config. A Hub config_path is resumed
in place (its checkpoint config already targets that repo); a local config_path
has its checkpoint uploaded to a new private repo first and the run is forced to
push back to it. The pod command carries --job.target=local so the checkpoint's
saved job.target can't make the pod re-dispatch itself, and the user's CLI
overrides are forwarded so a remote resume matches the same local command.
ensure_dataset_available is hoisted before the resume/fresh branch since it
applies to both.
* docs(train): document resuming from a Hub checkpoint, locally and on jobs
Show that --config_path accepts a Hub repo id for --resume, and that adding
--job.target resumes on HF Jobs (uploading a local checkpoint/dataset first).
* fix(jobs): default remote job timeout to 2d instead of the platform default
HF Jobs applies its own short 30-minute timeout when none is sent, which
silently kills long training runs. Pass an explicit, generous 2d cap by
default; users can still override --job.timeout to fail fast or extend it.
* fix(jobs): drop --dataset.root on resume + restore keyboard-control docs
Address the latest Claude review on #3856:
- _build_resume_job no longer forwards --dataset.root to the pod (a
host-local path it can't read); the fresh-run path already nulls it in
build_remote_config_file, so this makes resume consistent. Add a unit
test for _pod_forwarded_args covering the drop in both flag forms.
- Restore the display-independent keyboard-control docs (n/r/q letter
equivalents + X11/Wayland/headless Tip) in il_robots.mdx that this
branch was stale on relative to main (#3875).
* fix(jobs): handle str-typed job stage from huggingface_hub
inspect_job's status.stage is an enum (with .value) in some
huggingface_hub versions and a plain str in others. The poller
assumed the enum shape, raising "'str' object has no attribute
'value'" on resume for users on the str-returning version.
Read it via getattr(..., "value", ...) so both shapes work, and
parametrize the poll test over enum and str stages so the str case
is actually exercised (the old mock only ever simulated the enum).
* refactor(jobs): use relative import for ensure_dataset_available
* refactor(train): hoist submit_to_hf import to module top
The `from lerobot.jobs import submit_to_hf` was a function-local import in
train(); it pulls no heavy/optional deps and has no circular-import risk, so
move it to the top-level import block.
* refactor(train): hoist _remote_target_in_argv imports to module top
Move `import sys` and `from lerobot.configs import JobConfig` out of the
function body and into the top-level import block.
* refactor(utils): use relative import for sibling constants in hub.py
`from lerobot.utils.constants import CHECKPOINTS_DIR` was the odd one out in
utils/ — sibling modules there are imported relatively (.constants, .errors,
.utils, ...). Match that convention.
* refactor(jobs): hoist LeRobotDataset import, guard dataset extra at package init
Move the `from lerobot.datasets import LeRobotDataset` import to the top of
dataset.py and relocate the `require_package("datasets", extra="dataset")`
guard to the jobs package __init__, per review feedback.
* test(jobs): skip test_hf if datasets extra is missing
lerobot.configs.train pulls in datasets at import time, so the module
fails to collect without lerobot[dataset]. Guard with importorskip,
matching the convention in tests/training/test_multi_gpu.py.
* test(jobs): skip test_dataset if datasets extra is missing
tests/jobs/test_dataset.py imports lerobot.jobs.dataset, which triggers
the require_package("datasets") guard in lerobot/jobs/__init__.py at
import time. Without lerobot[dataset] the module fails to collect in the
base CI tier. Guard with importorskip, same as test_hf.py.

Add inline offline validation with train/eval split (#3824)
* refactor(training): rename eval_freq to env_eval_freq - Rename eval_freq to env_eval_freq to distinguish sim environment evaluation from offline loss evaluation. * feat(training): add inline offline validation with train/eval split - Add eval_split config for balanced per-task holdout - Add eval_steps for periodic inline eval loss computation - Add max_eval_samples to cap eval cost * fix(datasets): remap absolute indices in __getitem__ for filtered datasets * fix(train): vectorize eval subset selection for max_eval_samples * fix(datasets): Move the remapping into EpisodeAwareSampler via absolute_to_relative_idx * fix(validation): add eval_split range check and eval_steps warning Validate eval_split is in [0.0, 1.0) to prevent garbage splits from out-of-range values. Raise when eval_steps > 0 but eval_split is 0.0 since no offline eval will run. * fix(train): prepare eval dataloader with accelerator for multi-GPU Prepare eval_dataloader through accelerator.prepare() so eval data is sharded across ranks instead of duplicated. Reduce eval_loss across ranks with mean reduction for consistent logging. * fix(test): rename eval_freq to env_eval_freq for multi-GPU training |

fix(datasets): enforce one parquet row group per episode in v3 data writes (#3807)
* fix(datasets): enforce one parquet row group per episode in v3 data writes LeRobot v3 data shards must hold exactly one row group per episode so a reader can fetch episode i with pq.ParquetFile(path).read_row_group(i) (a byte-range read) instead of loading the whole shard. The recording writer already does this (one write_table per episode); the aggregate and lerobot-annotate re-write paths instead concatenated many episodes and wrote them in one shot, collapsing the file to a single row group. - io_utils: add write_table_one_row_group_per_episode (one ParquetWriter, one write_table per episode — same pattern as the recording writer); to_parquet_with_hf_images embeds images then writes per-episode row groups; to_parquet_one_row_group_per_episode wraps it for plain frames - aggregate: route non-image data writes through the per-episode writer; leave the episodes-metadata parquet untouched (already one row/episode) - annotate: rewrite shards via the per-episode writer instead of a single bulk pq.write_table - tests: invariant coverage through the aggregate (image + video) and annotate paths No change to on-disk schema, paths, naming, rollover thresholds, or compression.

feat(edit-dataset): add concatenate_videos opt-out to merge (#3663)
* feat(edit-dataset): add `concatenate_videos` opt-out to merge
When merging datasets, source mp4s are concatenated into shards capped at
`video_files_size_in_mb` (default 200 MB). This is great for dataloader
throughput but destroys per-episode (or per-source) video boundaries,
which is undesirable when you want to inspect, ship, or reuse the
individual mp4s.
Add a `concatenate_videos: bool = True` knob plumbed through
`MergeConfig` → `merge_datasets` → `aggregate_datasets` → `aggregate_videos`.
When False, each source mp4 is copied 1:1 to its own destination mp4 with
no re-muxing, so the merge preserves source video boundaries.
Usage:
lerobot-edit-dataset \
--new_repo_id user/merged \
--operation.type=merge \
--operation.repo_ids "['user/a', 'user/b']" \
--operation.concatenate_videos=false
Defaults are unchanged; the dataloader path is unaffected because the
`episodes.parquet` `from_timestamp`/`to_timestamp` index keeps working
regardless of whether each mp4 holds one or many episodes.
* feat(edit-dataset): extend concatenate opt-out to data files
Following review, add a concatenate_data flag mirroring concatenate_videos,
threaded through MergeConfig, merge_datasets, aggregate_datasets, aggregate_data
and append_or_create_parquet_file. Metadata index files still always concatenate.
Also trim the verbose docstrings and comments since the names are
self-explanatory, and extend the existing merge test to cover data files.

feat: language annotation pipeline (#3471)
Steerable annotation pipeline (lerobot-annotate) that populates the language_persistent and language_events columns introduced in PR 1 (#3467) directly into data/chunk-*/file-*.parquet. This is PR 2 of the three-PR plan: PR 1 (Add extensive language support #3467): schema + DSL + rendering, base of this PR PR 2 (this PR): annotation pipeline writing into PR 1's columns PR 3: model with language prediction and runtime A VLM (Qwen-VL family, served on vLLM) watches each episode's video and emits grounded language annotations: subtasks, plans, memory, task rephrasings, interjections + speech, and per-camera VQA. The pipeline is built for production annotation at scale — single-camera grounding, embedded-frame inputs, a describe-then-segment grounding flow, and a deterministic full-episode coverage guarantee — informed by Scale's dense-captioning findings (representation > sampling, rules > reasoning, model capacity is the biggest lever, two-pass systems compound errors) |

feat(datasets): deterministic, resumable shuffling for EpisodeAwareSampler (#3769)
* fix(datasets): expose a generator on EpisodeAwareSampler for distributed shuffle sync In distributed training, accelerate can only synchronize the shuffle permutation across ranks when the sampler exposes a generator attribute. EpisodeAwareSampler shuffled via the global torch RNG, so disjoint batch shards relied on every rank's global CPU RNG staying in lockstep forever; any rank-asymmetric RNG consumption (e.g. eval rollouts on the main process only) silently desynced the permutations and ranks trained on overlapping/missing samples. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(train): seed sampler generator and gate dataset download per node - Pass a generator seeded with cfg.seed to EpisodeAwareSampler so accelerator.prepare registers it as the synchronized RNG and the shuffle order is reproducible. - Gate the initial make_dataset call on is_local_main_process instead of is_main_process: the global main process only exists on node 0, so on every other node all local ranks were downloading the dataset and building the Arrow cache concurrently. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(datasets): add DeterministicEpisodeAwareSampler with O(1) memory and sample-exact resume Add a sampler that never materializes frame indices: it stores only per-episode boundaries (numpy, a few bytes per episode) and maps logical positions to frame indices on the fly with searchsorted. Shuffling uses a seeded Feistel permutation over [0, num_frames) (cycle-walking to the exact domain), so the data order is a pure function of (seed, epoch): - no RNG state to synchronize across distributed ranks, - constant memory and zero epoch-boundary cost at any dataset size, - O(1) seek to any position, enabling sample-exact resume. Opt in with --deterministic_sampler=true. On resume, lerobot-train maps the checkpointed step back to (epoch, start_index) via compute_sampler_state and continues at the exact sample where the run left off (up to accelerate's even_batches padding at epoch boundaries). The shuffle is pseudo-random rather than a true uniform permutation, the standard trade-off in large-scale training loaders. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(datasets): fold deterministic mode into EpisodeAwareSampler Instead of a parallel DeterministicEpisodeAwareSampler class, extend the existing EpisodeAwareSampler with a deterministic=True mode (seeded Feistel permutation, epoch auto-advance, state_dict/load_state_dict). The default mode is behavior-identical: same torch.randperm consumption and the same generator contract accelerate synchronizes; the O(N) Python index list is replaced by O(num_episodes) boundary arrays in both modes, with `indices` kept as a back-compat property. Passing a generator together with deterministic=True is rejected, and the state/seek methods raise outside deterministic mode. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(train): enable deterministic_sampler by default Deterministic data order (sample-exact resume, no cross-rank RNG sync, O(1) sampler memory) is now the default for map-style training; set deterministic_sampler=false to restore the legacy RNG-based shuffle. Streaming datasets ignore the flag (the sampler path only applies to map-style datasets), replacing the previous hard validation error so streaming configs keep working with the new default. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(datasets): default EpisodeAwareSampler to deterministic mode and trim comments deterministic=True is now the class default as well as the training default; the legacy RNG path requires an explicit deterministic=False (the train script's non-deterministic branch passes it). Docstrings and inline comments slimmed down across the changed files. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(sampler): drain resumed trillion-frame sampler via iter() to avoid list() prealloc list(sampler) calls PyObject_LengthHint -> __len__ (the full 10**12 epoch length) and preallocates that many slots before iterating, OOMing even though the resumed epoch only yields 3 frames. Collect through the iterator (no length hint) so the test exercises the real O(1) seek/drain instead of CPython's list growth heuristic. * fix(datasets): guard Feistel cycle-walking loop against non-convergence Replace the unbounded while True in EpisodeAwareSampler._permute with a bounded for loop capped at _MAX_CYCLE_WALK_STEPS (100) and raise RuntimeError if the cycle-walk fails to land in [0, num_frames). The loop is expected to converge in <4 steps on the chosen power-of-two domain, so the bound is a safety net that should never trip in practice but prevents a pathological infinite loop. https://claude.ai/code/session_01HQ15tFrBsHYScjGWosEv22 * fix(datasets): make deterministic-sampler resume robust to world-size changes compute_sampler_state mapped a checkpointed step back to (epoch, start_index) using the *current* num_processes, but the number of sampler positions a step consumes scales with the world size that produced it. Resuming on a different GPU count therefore landed on the wrong epoch/offset, silently re-seeing or skipping data. Record num_processes in training_step.json at checkpoint time and feed the checkpoint's value into compute_sampler_state on resume, so the data order resumes at the right position regardless of the new world size. Warn when the world size changed (the global offset is correct, but per-rank sample-exactness needs the same topology). Old checkpoints without the field fall back to the current world size. Also document compute_sampler_state's assumptions explicitly: num_processes / batch_size must match the checkpointing run, and accelerate's even_batches=True padding is mirrored by the ceil(... / num_processes) term. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Co-authored-by: Cursor <cursoragent@cursor.com> * style: apply ruff-format to lerobot_train.py Collapse the compute_sampler_state(...) call onto one line so the ruff-format pre-commit hook passes (fixes the failing CI check). Co-authored-by: Cursor <cursoragent@cursor.com> * refactor(datasets): use seeded torch.randperm instead of Feistel in EpisodeAwareSampler Drop the Feistel permutation (and its SplitMix64 hash / cycle-walking) in favor of a torch.randperm seeded from (seed, epoch). The deterministic mode keeps its key properties - data order is a pure function of (seed, epoch), so it reproduces on every rank with no global-RNG synchronization, and - state_dict / load_state_dict still resume sample-exactly, now by regenerating the epoch's permutation and slicing from the saved offset. Construction stays O(num_episodes) (only episode boundaries are stored, never a per-frame index list). The trade-off vs Feistel: the per-epoch shuffle is again O(num_frames) memory (the randperm tensor) and no longer O(1)-seekable, in exchange for ~30 fewer LOC and a truly uniform shuffle. Tests updated: the trillion-frame O(1) test is replaced with a boundary-storage check and a scale resume-exactness test. Co-authored-by: Cursor <cursoragent@cursor.com> * refactor(datasets): make EpisodeAwareSampler always deterministic With Feistel gone, deterministic and legacy modes were both just torch.randperm and the deterministic path strictly dominated (reproducible across ranks via the (seed, epoch) seed, no accelerate generator sync, resumable). Collapse to a single path and drop the redundant flag: - remove the `deterministic` and `generator` constructor args, `_iter_default`, and `_require_deterministic`; `set_epoch` / `state_dict` / `load_state_dict` are now unconditional - remove the `deterministic_sampler` train config field and the legacy generator branch in lerobot_train.py (non-streaming map datasets always use the sampler) - drop the now-obsolete generator/legacy tests Note: removes the `generator` kwarg from EpisodeAwareSampler (back-compat break vs main); the order is now a pure function of (seed, epoch), so no cross-rank RNG sync is needed. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(datasets): address sampler review (batch_size resume guard + docs) - Record batch_size in training_step.json alongside num_processes and feed the checkpoint's value into compute_sampler_state on resume; warn when it differs (per-rank sample-exactness needs the same batch size). - Document the set_epoch vs __iter__ auto-advance coupling on EpisodeAwareSampler (callers should rely on exactly one mechanism per run). - Note the broadened (reproducibility-breaking) sampler guard and the no-generator distributed sharding correctness in lerobot_train.py. - Add load_training_batch_size + parallel tests. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(train): download dataset once on the global main process Gate the training dataset download on the global is_main_process (download once to the shared dataset root, barrier, then every other rank reads the already-populated copy) instead of per-node is_local_main_process. LeRobotDataset skips its snapshot_download when try_load() succeeds, so no rank re-downloads. Assumes the dataset root / HF cache is on storage shared across nodes. Co-authored-by: Cursor <cursoragent@cursor.com> * chore(datasets): trim sampler comment and drop duplicate tests Remove the verbose dataloader-guard comment and the two EpisodeAwareSampler tests that duplicated existing validation/warning coverage (no coverage loss).

refactor(pi052): split pi05_backbone into pi_gemma + modeling_pi052
Eliminate the standalone pi052/pi05_backbone.py by distributing its contents: - Generic dual-expert transformer machinery -> lerobot/policies/pi_gemma.py (sdpa_attention_forward, compute_layer_complete, PaliGemmaWithExpertModel, get_gemma_config; the openpi width/depth config is renamed GemmaConfig -> GemmaVariantConfig to avoid clashing with transformers' GemmaConfig). These sit next to the existing PiGemma layer code they already depend on. - pi052-specific model + helpers -> pi052/modeling_pi052.py (PI05Pytorch, ActionSelectKwargs, make_att_2d_masks, pad_vector, resize_with_pad_torch, create_sinusoidal_pos_embedding, sample_beta, get_safe_dtype). DEFAULT_IMAGE_SIZE is duplicated as a plain constant in pi_gemma to avoid a pi_gemma -> pi05 import cycle. Additive to pi_gemma; pi0/pi05 unaffected. Verified bit-exact on pepijn223/pi052_robocasa_full (embed/predict/forward identical) and all 34 pi052 tests pass. Co-authored-by: Cursor <cursoragent@cursor.com> |

refactor(pi052): self-contained policy; revert pi0/pi05 to upstream main
The smolvla branch had modified the shared pi0/pi05 modeling + pi05 config to support pi052 (SDPA attention, layernorm/lm_head handling, optimizer foreach/fused/lm_head_lr_scale, embedding scaling). Decouple pi052 instead: - Vendor the PI0.5 backbone (PaliGemmaWithExpertModel, PI05Pytorch, helpers) into pi052/pi05_backbone.py (verbatim copy, no PI05Policy). - Flatten PI052Policy to subclass PreTrainedPolicy directly (no longer PI05Policy); inline the needed PI05Policy methods. - Restore optimizer_foreach/fused + get_optimizer_preset on PI052Config. - Revert pi0, pi0_fast, pi05 modeling and configuration_pi05 to origin/main (byte-identical), so the shared policies carry no smolvla modifications. Behavior verified bit-exact on pepijn223/pi052_robocasa_full: embed_language_ tokens, predict_action_chunk, and the fused flow+text+FAST training loss are identical before/after (max_abs_diff=0). pi052 tests pass (pre-existing stale-name collection errors unchanged).

Merge feat/language-annotation-pipeline into feat/smolvla-on-steerable
Bring the authoritative annotation pipeline from the annotation branch.
The annotation surface is forced to EXACTLY match feat/language-annotation-
pipeline (the annotation branch is the source of truth for annotation
code), which also removes smolvla's stale copies:
- deleted: steerable_pipeline/vocabulary.py, tests/annotations/test_
vocabulary.py, prompts/module_0_vocabulary.txt, module_1_action_record
.txt, module_3_vqa.txt, module_1_plan.txt, and the old module_* prompt
names (now plan_*/interjections_*/vqa.txt).
- synced: all of src/lerobot/annotations/, lerobot_annotate.py,
examples/annotations/, tests/annotations/, datasets/language.py,
tests/datasets/test_language.py, docs/annotation_pipeline.mdx.
Non-annotation conflicts resolved by union (keeping both branches' intent):
- pyproject.toml: keep smolvla's pi extra (+sentencepiece) and add the
molmoact2 extra from main.
- policies/factory.py: keep both dataset_repo_id (pi052 FAST tokenizer)
and dataset_meta (both are referenced); union the policy-type docstring.
- scripts/lerobot_train.py: keep smolvla's pi052 / use_relative_actions
processor-rebuild block.
- uv.lock: regenerated from the merged pyproject.

annotate: remove the action_record style/feature entirely
Drop the optional structured per-subtask action records — not a feature
we want to ship.
* language.py: remove 'action_record' from CORE_STYLES + PERSISTENT_STYLES
(and the matching assertion in tests/datasets/test_language.py).
* config.py: delete ActionRecordsConfig (verb/grasp vocabularies,
frames_per_subtask, emit_record_row) and the PlanConfig.action_records
field.
* plan_subtasks_memory.py: delete _extract_action_record and the
run_episode block that emitted style='action_record' rows; drop the
now-unused json / to_image_blocks imports.
* remove the plan_action_record.txt prompt.
* run_hf_job.py: drop the action_records comment.
Verified: 40 tests pass; pre-commit (ruff, mypy, bandit) clean.

annotate: compress conftest + pyproject comments (fix stale backend note)
The pyproject annotations-extra comment still described the removed
vllm/transformers in-process backends ('vllm preferred ... transformers
fallback', '_make_vllm_client'); rewrite it for the openai-only reality
and trim it. Also condense the conftest lazy-import NOTE. Comments only.

annotate: address review feedback — bug fixes, docs/code drift, naming, cleanup
Bugs
* validator: don't re-raise on unknown style. The second column_for_style
lookup (used to route persistent vs event) now sits in try/except so an
unknown style is recorded by _check_column_routing and skipped instead
of crashing the whole validation pass.
* general_vqa._target_cameras: when restrict_to_default_camera is set but
the configured camera_key isn't one the provider exposes, warn and fall
back to all cameras instead of returning a phantom key that KeyErrors
deep in frame decode.
* interjections: clamp interjection timestamps to frame_timestamps[0]
rather than a hardcoded 0.0 (datasets can start at non-zero t).
Docs / code drift
* annotation_pipeline.mdx: drop the phantom 'vocabulary discovery / phase
0 / --vocabulary.* / canonical_vocabulary.json' section (none of it
exists); describe the real describe->segment + coverage-stitch flow.
Soften the src/lerobot/tools/ + TOOL_REGISTRY reference to 'not part of
this PR' (matches tools.mdx, which already marks the runtime layer as
not-yet-implemented). Fix the --push_to_hub/--new_repo_id wording. Note
the default is now a single h200. Add a 'Contributing new modules'
section inviting module / prompt / quality contributions.
* executor docstring: six phases, no phantom phase 0.
run_hf_job.py
* add the Apache 2.0 license header (was flagged repeatedly).
* default to a single GPU: flavor=h200, parallel_servers=1, num_gpus=1
(scale to h200x4 noted in the docstring).
* pin the install to @main instead of the feature branch (won't break
after merge).
Naming / cleanup
* rename dest_repo_id -> new_repo_id across config / script / example /
test to match the LeRobot dataset edit tools.
* rename prompt templates module_N_*.txt -> descriptive (plan_*,
interjections_*, vqa.txt) and update every load_prompt() call.
* remove dead _messages_to_prompt (used only by the removed in-process
backends).
* declare _warned_decode_fail (frames) and _warned_no_camera (vqa) as
real init=False dataclass fields instead of getattr monkey-patches.
* scope bandit B607 to the two ffmpeg subprocess.run sites via
'# nosec B607' and drop it from the global skip list.
Tests
* fix stale canned-VLM markers ('ONE realistic interruption' ->
'compact interjection', 'Update the memory' -> 'compressed semantic
memory') and drop the dead 'concise hierarchical PLAN' plan responders
(plan generation is deterministic now) in run_e2e_smoke,
test_pipeline_recipe_render, test_modules.
* run_e2e_smoke now asserts interjection + speech rows are produced so a
stale marker can't silently pass again.
* drop remaining 'PR 1' / 'PR 2' references from test comments / names.
Verified: tests/annotations + tests/datasets/test_language +
tests/scripts/test_lerobot_annotate (31 passed); make-style E2E smoke
(interjections=1 speech_atoms=2); pre-commit (ruff, mypy, bandit,
prettier) clean.

tests(annotations): fix stale canned-VLM markers + action_record style assertion
The annotation tests had never actually run in CI (collection failed on
the missing 'datasets' extra); now that they do, three stale assertions
surfaced against the evolved pipeline:
* test_module1_plan_memory_subtask_smoke: the memory canned-responder
marker 'Update the memory' no longer appears in module_1_memory.txt
(now 'compressed semantic memory'), so the stub returned no memory
row and the {subtask,plan,memory} subset check failed. Marker
updated to match the current prompt.
* test_module2_mid_episode_emits_paired_interjection_and_speech: the
interjection marker 'Write ONE interjection' is now 'Write ONE
compact interjection' in module_2_interjection.txt, so 0 interjections
were emitted. Marker updated.
* tests/datasets/test_language.py::test_style_registry_routes_columns:
PERSISTENT_STYLES gained 'action_record' in this PR; add it to the
expected set.
These are test/prompt-marker syncs — no production behavior change.

tests(annotations): guard on the 'dataset' extra so base fast-test tier skips cleanly
Fast Pytest Tests failed at COLLECTION in the base '--extra test' tier
with 'ModuleNotFoundError: No module named datasets': tests/annotations/
conftest.py imported the fixture dataset builder (-> lerobot.datasets ->
the HF 'datasets' lib + pandas/pyarrow), which only ship under the
'dataset' extra, so the whole annotations package crashed.
Fix uses the repo's proven module-level guard pattern (see
tests/datasets/test_language.py), NOT a conftest-level importorskip —
verified empirically that pytest.importorskip raised during conftest
*import* is treated as a collection ERROR (exit 1), while module-level
importorskip is a clean SKIP.
* conftest.py: import build_annotation_dataset LAZILY inside the
fixtures so the conftest itself imports cleanly in every tier.
* test_modules / test_validator / test_writer / test_pipeline_recipe_
render: add module-level pytest.importorskip('datasets') +
('pandas') before the pyarrow / lerobot.* imports (# noqa: E402 to
match the existing convention). pyarrow-importing modules place the
guard before the pyarrow import.
* tests/scripts/test_lerobot_annotate.py: same guard (its _push_to_hub
path imports lerobot.datasets).
Result:
- base / hardware / viz tiers (no dataset extra): annotation tests
skip cleanly; the rest of the suite runs -> exit 0.
- dataset tier: datasets present -> guards pass through -> annotation
tests run with the stub VLM. The pipeline modules import only
stdlib + relative + lerobot.datasets (no module-level datatrove /
vllm / openai), so they import fine there.
