Switching the plan module to embedded frames (use_video_url=false)
exposed a context overflow: at frames_per_second=2.0 with the old
max_video_frames=128 default, a 480x640 episode embeds ~128 frames ≈
33-39k vision tokens, over the model's 32768 context — every plan call
died with 'Input length exceeds maximum context length' (HTTP 400),
crashing the whole annotation job.
The video_url path never hit this because the server downsampled; the
embedded path sends every sampled frame, so the frame count is a hard
token budget.
Fix:
* config default max_video_frames 128 -> 32 (~8-10k vision tokens,
comfortable headroom for the prompt + describe/verify passes).
Frames are still sampled UNIFORMLY across the whole episode, so
longer episodes are subsampled, not truncated — full temporal
coverage preserved, just coarser density.
* run_hf_job.py: frames_per_second 2.0 -> 1.0, explicit
--plan.max_video_frames=32, with a comment explaining the token
budget and the 'do not raise toward 128 with embedded frames' rule.
Only the plan module embeds the full episode; VQA (1 frame/tick) and
interjections (4-frame window) were never at risk.

Flip PlanConfig.subtask_describe_first and subtask_verify defaults
False -> True. Every subtask annotation now runs the 3-call grounding
+ pruning chain by default, since the single-call path reliably
hallucinates steps from the task text. Costs 2 extra VLM calls/episode;
disable with --plan.subtask_describe_first=false / --plan.subtask_
verify=false on easy datasets where fewer calls matter more than
label fidelity.
run_hf_job.py: drop the now-redundant explicit flags, leave a note that
the chain is default-on and how to opt out.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The single-call 'watch video -> emit subtask JSON' pattern makes the
VLM commit to structured output before reasoning about what it saw, so
it pattern-matches the task text and hallucinates steps. Split it into
an opt-in multi-call chain that grounds first and prunes last.
New PlanConfig flags (both default False -> single-call unchanged):
* subtask_describe_first: a grounding pass narrates ONLY what is
visible in the video (no subtask JSON yet). That description is
injected into the segmentation prompt via a new {observation_block}
placeholder, so the model segments its own grounded observations
instead of the instruction text. +1 VLM call/episode.
* subtask_verify: after segmentation, an adversarial pass re-watches
the video and drops any candidate subtask it cannot see. Can only
PRUNE (never add/rewrite/move) and fails open (keeps un-verified
spans if the call returns nothing). +1 VLM call/episode.
Implementation:
* _generate_subtasks now orchestrates describe -> segment -> verify.
* Factored span cleaning into _clean_spans (shared by segment + verify
outputs); added _describe_episode and _verify_subtasks helpers.
* New prompts module_1_subtask_describe.txt (returns {description})
and module_1_subtask_verify.txt (returns pruned {subtasks}).
* module_1_subtasks.txt gains a {observation_block} slot at the top.
run_hf_job.py enables both for the RoboCasa run (3 VLM calls/episode
for subtasks). Combined with single-camera grounding + the embedded-
frame path, this is the high-quality configuration.

Two fixes for 'subtasks describe actions not in the video' plus a way
to focus the whole pipeline on one camera.
ANTI-HALLUCINATION
1. _episode_video_block: when use_video_url is set but clip extraction
fails, FALL BACK to embedded frames instead of returning an empty
block. An empty block left the VLM with zero visual grounding, so
it invented subtasks from the task text alone — the likely root
cause of hallucinated steps. Now logs a warning and embeds frames.
2. module_1_subtasks.txt gains a GROUNDING preamble (overrides all
other rules): label only motion visible in specific frames; never
invent/anticipate/pad; max_steps is a CEILING not a target; atomic
demos may be exactly ONE subtask; the VIDEO is ground truth, not
the instruction text.
SINGLE-CAMERA GROUNDING
* New VqaConfig.restrict_to_default_camera (default False). When True,
the VQA module grounds on only the --vlm.camera_key stream instead
of iterating every camera — matching the plan / interjection
modules, which already use that single camera. Now the whole
pipeline can focus on one view (e.g. observation.images.base).
run_hf_job.py updated:
* use_video_url=false + frames_per_second=2.0 — embed frames directly
(most reliable; no silent text-only failure mode) with dense
grounding.
* vqa.restrict_to_default_camera=true — VQA on the single camera too.

Drops the replace_subtask_text option and the
_render_action_record_to_subtask_text renderer. Action records are now
strictly additive: when action_records.enabled=True the module emits
style='action_record' rows (the typed {verb,object,arm,grasp,dest,
mistake} schema) and NEVER rewrites the subtask text the policy
conditions on.
The render-back-to-text path was the source of corrupted subtasks
(navigation tasks produced 'move stove to stove', manipulation tasks
got spurious 'with left arm using pinch grip' suffixes). Reconstructing
natural-language subtasks from hallucinated structured fields is
inherently fragile, so the capability is removed rather than guarded.
Removed:
* ActionRecordsConfig.replace_subtask_text field
* PlanSubtasksMemoryModule._render_action_record_to_subtask_text
* the span['text'] = canonical_text overwrite in run_episode
Updated docstrings + run_hf_job.py comment accordingly. emit_record_row
(default True) is now the feature's only output.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three compounding bugs made RoboCasa annotation produce off-task
subtasks ('move stove to stove with left arm') and drifting
augmentations ('wander around the kitchen' for 'Navigate to the stove').
1. action_records.replace_subtask_text now defaults False.
Overwriting the VLM's subtask text with a reconstruction of
hallucinated {verb,object,arm,grasp,dest} fields is high-risk:
navigation / non-manipulation tasks don't fit the schema and render
to nonsense. Records are now additive by default (emit_record_row),
never silently replacing subtask text. Flip replace_subtask_text on
only for manipulation datasets verified to render cleanly.
2. _render_action_record_to_subtask_text drops a degenerate
destination that just echoes the object (verb=move object=stove
destination=stove -> 'move stove' instead of 'move stove to stove').
Also routes 'navigate' through the 'to <dest>' preposition family.
3. module_1_task_aug_axes.txt hardened: variants MUST preserve the
goal/destination. Explicitly forbids 'Navigate to the stove' ->
'wander around the kitchen'. Only wording / arm / orientation /
grasp may vary; verb meaning, object, and destination are fixed.
examples/annotations/run_hf_job.py — corrected for RoboCasa:
* derive_task_from_video=off (was =always). The dataset task string
is authoritative and is what eval conditions on; =always threw it
away, re-derived a hallucinated task from the video, and poisoned
every downstream subtask/plan row. THIS was the dominant cause.
* n_task_rephrasings=0 + task_aug_axes left off — RoboCasa eval uses
exact task strings, so augmentation is unused/harmful.
* action_records left off — manipulation schema doesn't fit atomic /
navigation tasks.
* plan_max_steps=6 to keep atomic-task decomposition tight.

VideoFrameProvider derived its default camera and camera list from
meta.camera_keys, which mixes image- and video-stored cameras. The
clip/decode paths read videos/<key>/from_timestamp, which only exists
for video keys, so an image-stored camera sorted first (e.g.
observation.images.wrist) crashed the plan phase with a KeyError.
Restrict the list and default to meta.video_keys. Add a regression test
and point the example job at the dataset's actual video camera. Skip
bandit B607 (ffmpeg/git are intentionally resolved via PATH).

Heterogeneous datasets (different tasks/scenes across episodes) don't
share a single small subtask + memory vocabulary, so the canonical
vocabulary phase narrowed every episode to the wrong target distribution.
Flip the example to free-form generation by default and document the
``--vocabulary.enabled=true`` switch for homogeneous datasets where the
canonical vocabulary still helps the downstream policy.
No pipeline-code changes: ``VocabularyConfig.enabled`` already gates
phase 0 (see ``executor.py:_run_vocabulary_phase`` and
``VocabularyConfig`` docstring) and falls back to free-form generation.

(test_module1_plan_memory_subtask_smoke,
test_module2_mid_episode_emits_paired_interjection_and_speech in

that test file doesn't exist on main, so the failures originate on

Hardcoding ``n_subtask_target=10`` and ``n_memory_target=6`` baked task
complexity into the config — a simple pick-and-place needs ~6, a
multi-step recipe needs ~20. The VLM already sees the clips, so let it
pick the count itself from what's recurring across episodes.
Drop both knobs from ``VocabularyConfig`` and the ``module_0_vocabulary``
prompt template. The prompt now says "decide the count yourself based
on what you see — the smallest set that still covers every recurring
phase" and adds an "each label must recur across the demos" rule so
the VLM filters out one-off motions.
Update the launcher script + docs to remove the old knobs.

Three stale things in the launcher script:
- ``--module_1/2/3.*`` no longer exist; review commit fd18beb renamed
the CLI namespaces to ``--plan/interjections/vqa``. Forwarded all
eight existing args to their new names.
- ``--push_to_hub`` is now a bool; the destination repo lives at
``--dest_repo_id``. Split the single positional into both args.
- ``openai`` was missing from the pip install list, which the prior
review review (claude bot, 2026-05-08) flagged — the default vlm
backend is ``openai`` so the job would have ImportError'd. Added.
Also expose the new phase 0 (canonical vocabulary discovery) knobs
explicitly: ``--vocabulary.sample_episodes``, ``--n_subtask_target``,
``--n_memory_target``. Defaults are sane (3 / 10 / 6) but worth
flagging in the example so the operator knows what they're running.
Update the docstring + section comments to match the current phase
layout (vocabulary → plan → interjections → vqa → writer).

**#1 Plan-update phase reports correct skip count.**
``_run_plan_update_phase`` only ran ``run_plan_updates`` for episodes
with at least one interjection but hardcoded ``episodes_skipped=0``.
The summary undercounted skipped episodes. Now returns
``len(records) - processed`` so processed + skipped == total.
**#2 ``run_hf_job.py`` installs ``openai``.**
The ``CMD`` block does ``pip install --no-deps lerobot[branch]`` then
explicitly lists transitive deps. ``openai`` was missing — and since
``VlmConfig.backend`` defaults to ``"openai"``, the job would have
``ImportError``'d when ``vlm_client._make_openai_client`` ran.
**#3 Dedupe subtask-span reconstruction.**
Module 1's ``_reconstruct_subtasks_from_rows`` (no ``and spans`` guard)
and Module 2's ``_read_subtask_spans`` (with the guard) had near-
identical logic. Promoted to ``reconstruct_subtask_spans`` in
``reader.py`` using the safer guarded form. Both modules now import
the single helper.
**#5 Atomic staging.py JSONL writes.**
Mirroring the parquet-writer fix from an earlier review round:
``EpisodeStaging.write`` now writes to a sibling ``.tmp`` and
``Path.replace`` atomically. A crash mid-write can no longer leave a
half-written JSONL that ``read()`` would then fail to parse.
**#6 Atomic ``info.json`` write.**
Same pattern in ``executor._ensure_annotation_metadata_in_info`` —
``info.json`` is load-bearing for dataset metadata, so partial writes
brick the dataset.
**#7 Writer's role-key guard.**
``_normalize_persistent_row`` and ``_normalize_event_row`` accessed
``row["role"]`` directly while every other field used ``.get()``.
Pre-validate ``"role" in row`` and raise a friendly ``ValueError``
naming the row, so a future module that accidentally drops ``role``
fails with a triagable message instead of a bare KeyError deep in the
writer.
**#8 Last subtask span's ``end`` extends to episode end.**
``reconstruct_subtask_spans`` (the new shared helper) takes an optional
``episode_end_t``. When provided, the final span's ``end`` is closed
to that timestamp instead of equalling its own ``start`` (zero
duration). Both Module 1's plan-update pass and Module 2's interjection
anchoring pass ``record.frame_timestamps[-1]``, so downstream "current
subtask at refresh_t" lookups no longer miss refreshes that land
inside the final span.
Sweep: 66 passed, 0 failed. Pre-commit clean.

Test follow-up:
- `tests/annotations/test_pipeline_recipe_render.py` — PR 1 deleted
`src/lerobot/configs/recipes/pi05_hirobot.yaml` (review feedback:
remove the canonical-recipe file; recipes are user-supplied). The
cross-PR contract this test guards is "the recipe DSL renders
non-empty messages from pipeline output", which doesn't depend on
any specific YAML, so the test now builds an inline blend recipe
with the same coverage. Passes.

* feat: HIL data collection, RTC interpolator, and action queue improvements
- Add Human-in-the-Loop (HIL) data collection examples (sync + RTC)
- Add HIL data collection documentation
- Add ActionInterpolator for smoother policy control at higher rates
- Integrate interpolator into lerobot-record and eval_with_real_robot
- Add action queue clear() and get_processed_left_over() methods
- Add rtc/__init__.py for cleaner imports
* docs: expand Related Work section with paper summaries
* fix: only record dataset frames at original fps, not at interpolated rate
The interpolator speeds up robot control (e.g. 2x) but dataset frames
should still be recorded at the original fps. Interpolated-only
iterations now only send actions to the robot without writing to the
dataset.
* refactor: merge HIL sync and RTC scripts into single file with --rtc.enabled toggle
Combines hil_data_collection.py and hil_data_collection_rtc.py into one
script. RTC is toggled via --rtc.enabled=true (defaults to off for sync
inference). Deletes the separate hil_data_collection_rtc.py and updates
docs to reflect the single-script usage.
* test: add ActionInterpolator test suite (29 tests)
Covers constructor validation, passthrough (multiplier=1), 2x and 3x
interpolation with exact value checks, reset/episode boundaries,
control interval calculation, multi-dim actions, and simulated
control loop integration.
* test: add ActionQueue + ActionInterpolator integration tests
Verifies the interpolator doesn't interfere with RTC's leftover chunk
tracking: queue consumption rate matches base fps regardless of
multiplier, get_left_over/get_processed_left_over only change on
queue.get(), merge preserves smooth interpolation across chunks,
and interpolator reset is independent of queue state.
* feat: register SO follower/leader configs in HIL script
Adds SOFollowerRobotConfig and SOLeaderTeleopConfig imports so
SO100/SO101 robots can be used via --robot.type=so_follower
and --teleop.type=so_leader. Updates docs accordingly.

* fix(bi_openarm): use kw_only=True to fix dataclass field ordering
BiOpenArmFollowerConfig overrides `id` with a default, making it
positional in the child — non-default `left_arm_config` then follows a
default field, which Python dataclasses forbid. Adding kw_only=True
(matching the parent RobotConfig) removes positional constraints.

- Add delta action detection and logging to eval_with_real_robot.py
- Add delta actions documentation to pi0 and pi05 READMEs
- Fix ruff lint issues in test_delta_actions.py
- Add test_rtc_delta_actions.py (24 tests) covering:

- State rebasing approximation bounds
- Non-delta policy compatibility

- Replace decorative comment separators in test files with plain section headers
- Add attribution comments for 1e-6 epsilon in normalize_processor.py (from OpenPI)
- Remove debug logging blocks from lerobot_train.py
* refactor: extract compute_delta_action_stats into compute_stats.py
Move the ~70-line inline delta action stats block from lerobot_train.py
into a dedicated function in compute_stats.py, where all other stats
computation already lives. The training script now calls it in 6 lines.
* refactor: remove unused get_processed_left_over from ActionQueue
This method was never called outside of tests. Leftover actions for RTC
guidance are always retrieved via get_left_over() (delta/original space).
* revert: remove logging-only changes from eval_with_real_robot.py
The delta actions detection helper and log message added no functional
value — the script already handles delta policies correctly via the
processor pipeline.
* refactor: use ACTION/OBS_STATE constants instead of hardcoded strings
Replace hardcoded "action" and "observation.state" with ACTION and
OBS_STATE from utils.constants in compute_stats.py, dataset_tools.py,
and lerobot_train.py.
* style: remove stray blank lines in training loop
* refactor: move delta action stats to preprocessing step, remove on-the-fly computation
- Remove on-the-fly compute_delta_action_stats from lerobot_train.py
- Rewrite recompute_stats to delegate action stats to compute_delta_action_stats
(chunk-based sampling matching what the model sees during training)
- Add chunk_size parameter to recompute_stats for delta action computation
- Add delta actions documentation to pi0.mdx and pi05.mdx
* feat: add recompute_stats CLI operation to lerobot-edit-dataset
* fix(tests): relax quantile normalization test tolerance for 1e-6 epsilon
* chore: remove agents_memory/pr_details.md from repo
* refactor: rename delta actions to relative actions throughout
What OpenPI calls "DeltaActions" is actually UMI's "relative trajectory"
representation: each action in the chunk is an offset from the current
state, not from the previous action. This avoids error accumulation.
Renamed across all source, tests, docs, and CLI:
- DeltaActionsProcessorStep → RelativeActionsProcessorStep
- to_delta_actions → to_relative_actions
- use_delta_actions → use_relative_actions
- delta_exclude_joints → relative_exclude_joints
- compute_delta_action_stats → compute_relative_action_stats
- delta_action_processor.py → relative_action_processor.py
- test_delta_actions.py → test_relative_actions.py
Kept as-is: AbsoluteActionsProcessorStep (converts TO absolute),
registry ID "delta_actions_processor" (backward compat), and unrelated
delta references (IK pipeline, Robosuite, RA-BC metrics, gym envs).
* docs: add Action Representations guide
Dedicated page explaining absolute, relative, and delta actions with
numerical examples, joint vs EE space, and how to use kinematics
pipelines and the relative action processor. References UMI paper
(Chi et al., 2024) for the terminology.
* docs: remove redundant OpenPI naming note from action representations
* docs: remove opinionated OpenPI reference from delta actions section
* docs: replace ASCII diagram with UMI paper figure
* docs: remove OpenPI reference from action representations
* docs: use HF-hosted image instead of local asset
* docs: clarify figure attribution
* revert: restore original normalization epsilon behavior
The 1e-6 unconditional epsilon change perturbed all normalized values,
breaking backward compatibility tests. The original approach (1e-8 eps
for MEAN_STD, conditional torch.where for QUANTILES) already handles
division by zero correctly without affecting non-degenerate cases.
* fix: restore delta_action_processor.py used by phone/RL teleop
The rename commit incorrectly deleted delta_action_processor.py and
duplicated its classes into relative_action_processor.py. Restore the
original file and import from it instead.
* fix(processor): address PR #2970 review comments
- Remove shebang from relative_action_processor.py (library module, not script)
- Add device alignment in to_relative_actions/to_absolute_actions so _last_state
on CPU doesn't cause cross-device errors when actions are on CUDA
- Rename delta_step → relative_step in AbsoluteActionsProcessorStep for naming
consistency; update factory.py, all processor files, and tests
- Expand _reconnect_relative_absolute_steps docstring to explain why post-hoc
rewiring is needed after deserialization
- Fix off-by-one in compute_stats.py: sample_upper_bound = total_frames - chunk_size + 1
so last valid start index is included and total_frames == chunk_size is not rejected
- Remove redundant NOTE comment in processor_pi05.py (duplicated two lines below)
- Fix pi0_fast processor ordering: move relative_step before NormalizerProcessorStep
so normalizer sees delta actions (matching pi0/pi05); flip postprocessor to
unnormalize → absolute accordingly. Relative stats are now required for all pi models
- Revert use_relative_joint_actions_aloha → use_delta_joint_actions_aloha in
configuration_smolvla.py (preserve existing public API)
- Update action_representations.mdx: add missing joint to 6-DOF example, fix
'based on a figure', clarify pi family ordering, add RTC compatibility section
* update rtc link

This PR extends the integration of Unitree g1 with the LeRobot codebase. By converting robot state to a flat dict we can now record and replay episodes (example groot/holosoma scripts need to be adjusted as well). We also improve the simulation integration by calling .step @ _subscribe_motor_state instead of it running in a separate thread. We also add ZMQ camera to lerobot, streaming base64 images over json

* Add basic support for PEFT adapter methods
This changes adds support for training policies with much less parameters
by applying adapter methods such as LoRA on specific parts of the policies
and therefore possibly higher learning rates / batch sizes.
To make this as accessible as possible I thought it useful to provide
defaults for `target_modules` and `modules_to_save`. Currently only SmolVLA
has such defaults but when we agree that this change is useful I will set
out to generate more such defaults. While the user can override these
settings, they are expected to only change the peft_method, rank and init_type
parameters.
* Implement loading of PEFT adapters
Loading a PEFT adapter is currently done by initializing a policy with default config
and then applying the adapter on the resulting model. This has the obvious drawback
that any configurations done during training are not applied in the adapted model.
Currently the `use_peft` attribute of `PreTrainedConfig` is only set during loading
to signal the following code that it has to deal with a PEFT adapter. However
we could imagine a scenario where this is already set at training time and stored
alongside the adapter.
* Store policy config alongside PEFT checkpoint
Before this change the PEFT-wrapped policy did not save the policy's config
alongside the adapter config / weights which prevented us from changing the
policy config. Now the policy config is saved both in full training and PEFT
training.
This change makes loading the PEFT policy adapter much easier as well.
* Add default config for ACT
* Support targets like `all-linear`
* Formatting
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix failing tests
* Remove PEFT compatibility changes in config
We'll wait for the PEFT release that fixes this for good.
* Remove `use_peft` parameter from training script
Instead we make the PEFT config optional which has the same effect.
* Log adapter config to WandB
* Better documentation for CLI arguments
* Don't unload & merge the PEFT model
This can make things hard when using quantized layers (user expects quantized base layers with
unquantized adapters for example, merging defaults to upcast the layers leading to higher
memory).
* Correct way of identifying when to save config
* Add CLI end-to-end tests
Currently there don't seem to be any way to test the CLI commands.
Since this change mostly happens in those I thought it best to add
a way to test these commands end-to-end.
More integrated commands like `lerobot-record` need patching but
standalone commands like training seem to work fine.
* Update default targets
Removed ACT since it doesn't make sense to fine-tune ACT without having it pretrained beforehand.
SmolVLA and Pi0/0.5 are much more senseful targets.
* Clean up loading code
- Centralized instantiation of the PEFT wrapper in `make_policy` for inference
(e.g. in `lerobot-record`)
- Training a PEFT policy also sets `cfg.use_peft` so that all inference code loading
the policy can rely on that attribute to identify if PEFT loading is needed
- Modified RTC example to also include PEFT policies. Mostly because this is an example
I'm currently exploring.
* Make sure push_to_hub works
Since PEFT only wraps `push_to_hub` and not `push_model_to_hub`, the reference
to `self` in `policy.push_model_to_hub` is the unwrapped policy which, of course,
doesn't know anything about PEFT.
To make the upload process aware of PEFT, we pass the unwrapped policy down to
`push_model_to_hub` as a kwarg. This is not ideal but I think it is the best way
for now.
* formatting
* Warn when encountering from-scratch-training
* Revamp pretrained model loading
There were quite a few factors that convinced me that the status quo
is able to load pretrained models from the PEFT adapter config but
in fact that didn't work.
This commit fixes the following things:
- policies wrapped in PEFT will now have a `name_or_path` attribute
containing the name or path of the pretrained model we're fine-tuning
- we further assume that SmolVLA without `pretrained_path` and
`load_vlm_weights==False` must be an user-side error
- we assume that using PEFT on from-scratch-policies must be
an user-side-error
* Make it possible to unset policy features
This is necessary to train pre-trained policies on new datasets so that the
features are inferred from the new dataset and not from the pretrained
policy.
* Use correct loading for PEFT in RTC example
* Make it possible to use PeftModels in eval
* Add test checking that PEFT actually reduces params
* Adapt state/action projections instead of full-finetuning
There doesn't seem to be a benefit to fully fine-tune these layers
over just adapting them, so we do that instead.
* Disallow PEFT training on non-pretrained policies
At first I thought it would make sense to have this feature
in case you want to fine-tune a pre-trained section but in the
end it makes more trouble than it's worth.
It's still possible to allow this in the future when a concrete
need arises.
* Add basic documentation
* Formatting
* Add peft as extra dependency, mark tests
Fast tests currently fail because of the missing dependency.
* Fix pre-commit issues
* Add walx <> peft conflict for uv
* Exclude peft from pi install for now

- After each Euler step, retrieve most recent debug step from tracker
- Extract correction, x1_t, err from debug step for plotting
