Steven Palma bf9877fa0b test(groot): regression coverage and CI guards for the N1.7 review fixes
Adds/updates unit tests for the N1.5 removal surfaces (config, checkpoint
markers, removed processor steps, v2 action-unpack registration), the
legacy-default remap warnings, action_decode_transform auto/none resolution,
2-D action decoding, the per-instance raw-state cache and pack/decode
reconnection, raw-checkpoint stats fallback and override handling, camera-match
warnings, bf16 handling, and backbone loading kwargs. Adds pytest.importorskip
guards so the fast_tests tiers pass without transformers, and asserts the
training forward pass returns a finite loss.

Note: these tests exercise symbols introduced by the GR00T N1.7 source PRs
(source-core, backbone); merge those for green CI on this branch.

nv-sachdevkartik 68f869b7a0 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.

nv-sachdevkartik 750358895b 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.

nv-sachdevkartik bc4d0db8f4 docs(groot): drop WHY TWO ENVIRONMENTS block from parity test docstring 2026-06-12 08:06:33 +00:00
nv-sachdevkartik 45e273b806 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).

nv-sachdevkartik 8b5f56b63c 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.

nv-sachdevkartik 9f1ee224cb 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.

Maxime Ellerbach 2e9cd87bbd feat(policies): add VLA-JEPA (#3568)
* first commit

* feat(policies): add VLA-JEPA

* feat(policies): add VLA-JEPA

* support vla_jepa

* (feat)policies: add VLA-JEPA

* linting

* adding deps to pyproject.toml

* updating uv lock

* adding guards to avoid needing transformers and diffusers for type checking and basic tests

* fixing action and state dim

* fix warnings with qwen processor kwargs

* fixing wm_loss not propagating

* adjusting obs steps, tublets size to match original implementation

* some more fixes to be closer to the original implem

* adding more tests to ensure good coverage

* align VLA-JEPA architecture with original checkpoint

- Remove stale `action_num_heads` / `action_attention_head_dim` config fields;
  DiT head dimensions are now always derived from the preset (DiT-B/L/test).
- Add `num_target_vision_tokens` and `action_max_seq_len` config fields required
  by the action head's future-token embedding and positional embedding tables.
- Fix default `qwen_model_name` to 2B (matches all released checkpoints).
- Rename `ActionEncoder` attrs w1/w2/w3 → layer1/layer2/layer3 to match
  checkpoint key names; replace `nn.Sequential` decoder/state-encoder with
  `_MLP2` (layer1/layer2 naming).
- Fix `VLAJEPAActionHead` to size ActionEncoder and StateEncoder at `inner_dim`
  (DiT input width) rather than `action_hidden_size` (DiT output width).
- Rename `DiT.blocks` → `transformer_blocks` and `attn` → `attn1` to match
  checkpoint; add alternating cross/self attention (even blocks cross-attend to
  Qwen context, odd blocks self-attend).
- Add `DiT-test` preset for unit tests.
- Rewrite `ActionConditionedVideoPredictor` with explicit ViT-style blocks
  (`_PredictorBlock` with fused qkv) to match checkpoint structure; rename
  `encoder`/`norm`/`proj` → `predictor_blocks`/`predictor_norm`/`predictor_proj`.

* propagate action_is_pad masking through VLA-JEPA policy pipeline

Pass the `action_is_pad` tensor from the batch through to the action head
so padded timesteps are excluded from the flow-matching loss.

* update VLA-JEPA tests for arch changes and action_is_pad

- Switch conftest to use `action_model_type="DiT-test"` now that
  `action_num_heads` / `action_attention_head_dim` have been removed.
- Add action_head tests covering fully-padded loss (zero) and equivalence
  of action_is_pad=None vs all-zeros mask.
- Remove obsolete `test_native_to_lerobot_wm_only` test.

* add VLA-JEPA documentation

Covers architecture overview, pretrained checkpoints, config reference,
training/eval commands for LIBERO-10, and guidance on fine-tuning for
single-camera datasets.

* add one-shot script to convert ginwind/VLA-JEPA checkpoints to safetensors (will remove once migrated)

* make default params more aligned with paper and pretrained models
- adding possibility of freezing qwen backbone and world model
- added tests for weight loading

* trying out to re-init the action head to avoid pretraining dimension mismatch

* allow different state dim and action dim

* removing missleading future_action_window_size to just use chunk_size

* lots of changes to make existing weights work, need to massively refactor the pre and post processing

* refactoring into using pre and post processor

* pre-commit cleanup

* fixing doc defaults args

* docs(benchmarks): add benchmark integration guide and standardize benchmark docs

Add a comprehensive guide for adding new benchmarks to LeRobot, and
refactor the existing LIBERO and Meta-World docs to follow the new
standardized template.

Made-with: Cursor

* refactor(envs): move dispatch logic from factory into EnvConfig subclasses

Replace hardcoded if/elif chains in factory.py with create_envs() and
get_env_processors() methods on EnvConfig. New benchmarks now only need
to register a config subclass — no factory.py edits required.

Net -23 lines: factory.py shrinks from ~200 to ~70 lines of logic.

Made-with: Cursor

* docs(benchmarks): clean up adding-benchmarks guide for clarity

Rewrite for simpler language, better structure, and easier navigation.
Move quick-reference table to the top, fold eval explanation into
architecture section, condense the doc template to a bulleted outline.

Made-with: Cursor

* fix link

* fix task count

* fix: enable SmolVLA eval on LIBERO with custom camera mappings

- Thread camera_name_mapping from LiberoEnv config through to gym envs
- Sync features_map with camera_name_mapping in LiberoEnv.__post_init__
- Fix render() to use first available camera instead of hardcoded "image"
- Handle non-dict final_info in rollout by falling back to info["is_success"]
- Add use_peft legacy field to SmolVLAConfig for checkpoint compat
- Add defaults to GR00TN15Config init=False fields for transformers 5.3

Made-with: Cursor

Made-with: Cursor

* refactor: revert policy changes, keep env-only camera mapping fixes

- Revert GR00T N1.5 default_factory/default changes (transformers compat)
- Revert SmolVLA use_peft legacy field
- Apply ruff formatting fixes
- camera_name_mapping stays entirely in env/eval layer (no policy changes)

* feat(envs): lazy env init + AsyncVectorEnv as default for n_envs > 1

LiberoEnv and MetaworldEnv previously allocated GPU resources (EGL context,
OpenGL framebuffer) in __init__, before AsyncVectorEnv's fork(). Worker
processes inherited stale GPU handles, causing EGL_BAD_CONTEXT crashes on
first render.

Fix: defer OffScreenRenderEnv / MT1 construction to _ensure_env(), called on
first reset() or step() inside the worker subprocess. Each worker creates its
own clean context after fork().

Also fixes lerobot_eval.py:170 (add_envs_task TODO): replace with
env.call("task") which works with both SyncVectorEnv and AsyncVectorEnv.

AsyncVectorEnv is now the default for n_envs > 1; auto-downgraded to
SyncVectorEnv when n_envs=1 (no benefit, less overhead).

Expected speedup: ~15-20x for LIBERO Spatial with batch_size=50.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: close envs between tasks to prevent worker process accumulation

eval_policy_all never closed environments after each task completed,
causing AsyncVectorEnv worker processes to accumulate (N_tasks × n_envs).
This led to OOM, BrokenPipeError and EOFError on multi-task benchmarks.

Also fixes:
- AsyncVectorEnv compat in envs/utils.py (use get_attr/call instead of .envs)
- Tuple task handling in tokenizer_processor and lerobot_eval
- _LazyAsyncVectorEnv for deferred worker spawning in LIBERO

Made-with: Cursor

* fix(eval): use task_description instead of task for language conditioning

env.call("task") returns the LIBERO task name with underscores
(e.g. "pick_up_the_black_bowl_...") instead of the natural language
description ("pick up the black bowl ..."). The VLM tokenizes these
completely differently, causing 0.0 reward across all episodes.

* feat(eval): batch_size=auto + faster env loading

- batch_size=0 (default) auto-tunes based on CPU cores, capped by
  n_episodes and 64. Removes the need for users to guess the right
  value. The old batch_size > n_episodes error is replaced by silently
  clamping to n_episodes.
- _LazyAsyncVectorEnv accepts pre-computed spaces so only one temp env
  is created per suite (not per task). For libero_spatial (10 tasks)
  this avoids 9 redundant LiberoEnv instantiations during env setup.

Made-with: Cursor

* docs: add evaluation guide and update benchmarks doc

- New docs/source/evaluation.mdx covering lerobot-eval usage, batch_size
  auto-tuning, AsyncVectorEnv performance, tuning tips, output format,
  multi-task evaluation, and programmatic usage.
- Add evaluation page to _toctree.yml under Benchmarks section.

  link to the evaluation guide.

* ci(benchmarks): add isolated integration tests for libero and metaworld

Each benchmark gets its own Docker image (lerobot[libero] / lerobot[metaworld]
only) so incompatible dep trees cannot collide. A 1-episode smoke eval runs
per benchmark on GPU runners.

* fix(ci): set LIBERO_DATA_FOLDER to bypass interactive stdin prompt

libero/__init__.py calls input() to ask about a custom dataset path,

LIBERO_DATA_FOLDER skips the prompt entirely.

* fix(ci): pre-create libero config in Dockerfile to bypass stdin prompt

libero/__init__.py calls input() when ~/.libero/config.yaml is missing.
We write the config at image build time (without importing libero) so
the prompt never fires at runtime. Also trigger CI on pyproject.toml changes.

The config was pointing to /tmp/libero_init which doesn't exist.

* fix(eval): render_frame covers _LazyAsyncVectorEnv

isinstance(env, AsyncVectorEnv) silently skipped _LazyAsyncVectorEnv,

_LazyAsyncVectorEnv) hits the call("render") branch.

* refactor(envs): remove __del__ from _LazyAsyncVectorEnv

__del__ is unreliable as a cleanup mechanism. close() is already called
explicitly in the eval loop's finally block, so the finalizer is redundant.

* fix(eval): prefetch next task's workers after close to avoid GPU memory overlap

Previously, next task's AsyncVectorEnv workers were spawned while the
current task was still running, causing both tasks' GPU contexts to coexist.
Moving the prefetch start into the finally block (after env.close()) ensures
workers for task N+1 only spin up once task N has released GPU memory.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* refactor(envs): move _LazyAsyncVectorEnv to utils and apply to metaworld

_LazyAsyncVectorEnv lived in libero.py but metaworld had the same OOM
problem: all tasks' AsyncVectorEnv workers were spawned eagerly, wasting
GPU memory for tasks not yet running.

Move the class to envs/utils.py so both environments share it, then apply
the same is_async + lazy wrapping pattern in create_metaworld_envs.

* fix(envs): use forkserver context and close envs in test to prevent deadlock

AsyncVectorEnv with default fork context leaks worker processes between
test_policy parametrized cases; subsequent env creation deadlocks because
new forked workers inherit stale pipe FDs from previous test's leaked workers.

- configs.py: pass context="forkserver" to AsyncVectorEnv (matches _LazyAsyncVectorEnv)
- test_policies.py: call close_envs(envs) at end of test_policy to clean up workers

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(envs): default use_async_envs=False in create_envs and make_env

Tests that call make_env(n_envs=2) without passing use_async_envs were
getting AsyncVectorEnv, whose forked workers can't resolve gym namespaces
registered at runtime. Default to False (sync) so existing tests pass.

lerobot_eval.py explicitly passes cfg.eval.use_async_envs, so the CLI
async behaviour (controlled by EvalConfig.use_async_envs) is unchanged.

Pepijn 818892a38b feat(dagger): Add HIL/Dagger/HG-Dagger/RaC style data collection (#2833)
* 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.

default field, which Python dataclasses forbid. Adding kw_only=True
(matching the parent RobotConfig) removes positional constraints.

Pepijn 15934d8d08 feat(policies): add relative action support for pi0, pi0.5, and pi0_fast (#2970)
* Add option for pi family models to train with relative actions (relative to state)

* formatting

* add recomputation of stats and option to compute delta stats

* normalzie after delta conversion

* only recompute state for stats

* calulate chunk based stats

* sample 100k

* load from parquet

* sample 1m

* stats per chunck

* fix

* use quantiles

* stats for entire dataset

* fix

* max 1m frames

* compute before dist

* fix multi gpu processor bug

* Fix RTC with delta actions and OpenArms motor_type wiring

* feat: align pi0_fast delta actions with pi0/pi05 and add RTC integration tests

- Add delta_exclude_joints and action_feature_names to PI0FastConfig
- Move to_absolute_actions from modeling to processor pipeline for pi0_fast
- 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:
  - ActionQueue with delta vs absolute actions
  - RTC denoise step with delta leftovers
  - Full pipeline roundtrip (delta → RTC → absolute)
  - State rebasing approximation bounds
  - Non-delta policy compatibility
  - Multi-chunk consistency

* chore: clean up test comments, add OpenPI attribution, remove debug logging

- 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

* feat: compute relative action stats over full dataset with optional parallelism

Remove the 100k sample cap from compute_relative_action_stats and process
all valid chunks. Vectorize with numpy (pre-load actions/states, fancy
indexing + broadcasting) for a large speedup over the per-index HF dataset
loop. Add num_workers param for thread-based parallelism (numpy releases
the GIL). Update docs to show --push_to_hub for recompute_stats.

Altman e64fa667c3 fix(vqbet): use in-place fill_ to avoid overwriting DDP GPU buffers with CPU tensors (#3128)
* fix(vqbet): use in-place fill_ to avoid overwriting DDP GPU buffers with CPU tensors

When VQ discretization phase completes, the code was overwriting
register_buffer('discretized') and register_buffer('freeze_codebook')
with torch.tensor(True), which is created on CPU. DDP then fails in
_sync_buffers() with: RuntimeError: No backend type associated with
device type cpu. Fix by updating the buffers in-place with .fill_(True)
so device and registration are preserved.

Made-with: Cursor

* test(vqbet): add regression test for in-place buffer update during discretization

Verifies that discretize() updates the 'discretized' and 'freeze_codebook'
registered buffers in-place (via fill_()) rather than replacing them with new
CPU tensors. The test checks data_ptr() identity and that the tensors remain
registered buffers after the call. This prevents regressions of the DDP fix.

Made-with: Cursor

* test(vqbet): add GPU regression test to verify buffers stay on CUDA after discretize()

Directly catches the original DDP failure mode: when buffers are replaced with
torch.tensor(True) they land on CPU, causing NCCL to raise 'No backend type
associated with device type cpu' in _sync_buffers(). The GPU test places the
model on cuda:0 and asserts both buffers remain on CUDA after discretization.

Made-with: Cursor

* test(vqbet): simplify to single device-check test in test_policies.py

Per reviewer feedback: remove the separate test file and replace the two
CPU/GPU tests (with data_ptr checks) with a single focused test in
tests/policies/test_policies.py that only asserts the registered buffers
remain on the model device after discretize(). Uses DEVICE from tests/utils.py
so it runs on whatever device the CI/user selects (cpu, cuda, mps).

Made-with: Cursor

* style: fix import order in test_policies.py to pass ruff/pre-commit checks

* fix(sac): make temperature a property to fix checkpoint resume bug

Temperature was stored as a plain float and not restored after loading
a checkpoint, causing incorrect loss computations until update_temperature()
was called. Changed to a property that always computes from log_alpha,
ensuring correct behavior after checkpoint loading.

Eugene Mironov 8a915c6b6f [RTC] Real Time Chunking for Pi0, Smolvla, Pi0.5 (#1698)
* Add Real-Time Chunking (RTC) support for flow matching models

Implement Real-Time Chunking (RTC) for action chunking policies using flow
matching denoising. RTC enables smooth action transitions between consecutive
chunks by using prefix guidance during denoising.

Key features:
- RTCProcessor class with denoise_step method for RTC guidance
- Tracker system for debug tracking using time-based dictionary storage
- RTCDebugVisualizer with comprehensive visualization utilities
- Integration with SmolVLA policy for flow matching models
- Support for multiple prefix attention schedules (ZEROS, ONES, LINEAR, EXP)
- Configurable execution horizon and max guidance weight
- Example scripts for dataset evaluation and real-time control

Technical details:
- Uses autograd-based gradient computation for RTC corrections
- Time-based tracking eliminates duplicate step issues
- Proxy methods in RTCProcessor for cleaner API
- Full integration with LeRobot's policy and dataset systems

Files added/modified:
- src/lerobot/configs/types.py: Add RTCAttentionSchedule enum
- src/lerobot/policies/rtc/: Core RTC implementation
  - configuration_rtc.py: RTC configuration
  - modeling_rtc.py: RTCProcessor with denoise_step
  - debug_handler.py: Tracker for debug information
  - debug_visualizer.py: Visualization utilities
- src/lerobot/policies/smolvla/modeling_smolvla.py: RTC integration
- examples/rtc/: Example scripts and evaluation tools

* Fix rtc_config attribute access in SmolVLA

Use getattr() to safely check for rtc_config attribute existence
instead of direct attribute access. This fixes AttributeError when
loading policies without rtc_config in their config.

* fixup! Fix rtc_config attribute access in SmolVLA

* Add RTCConfig field to SmolVLAConfig

Add rtc_config as an optional field in SmolVLAConfig to properly
support Real-Time Chunking configuration. This replaces the previous
getattr() workarounds with direct attribute access, making the code
cleaner and more maintainable.

Changes:
- Import RTCConfig in configuration_smolvla.py
- Add rtc_config: RTCConfig | None = None field
- Revert getattr() calls to direct attribute access in modeling_smolvla.py

* Refactor RTC enabled checks to use _rtc_enabled helper

Add _rtc_enabled() helper method in VLAFlowMatching class to simplify
and clean up RTC enabled checks throughout the code. This reduces
code duplication and improves readability.

Changes:
- Add _rtc_enabled() method in VLAFlowMatching
- Replace verbose rtc_config checks with _rtc_enabled() calls
- Maintain exact same functionality with cleaner code

- Create output_dir at start of run_evaluation()
- Save all comparison images to output_dir
- Remove duplicate os imports
- Update init_rtc_processor() docstring to be more concise

* Fix logging buffering and enable tracking when RTC config provided

- Add force=True to logging.basicConfig to override existing configuration
- Enable line buffering for stdout/stderr for real-time log output
- Modify init_rtc_processor to create processor when rtc_config exists
  even if RTC is disabled, allowing tracking of denoising data

* Refactor SmolVLA plotting to use tracker data instead of local variables

Remove local tracking variables (correction, x1_t, error) from the
denoising loop and instead retrieve plotting data from the RTC tracker
after each denoise step. This makes the code cleaner and uses the
tracker as the single source of truth for debug/visualization data.

Changes:
- Remove initialization of correction, x1_t, error before denoising loop
- After each Euler step, retrieve most recent debug step from tracker
- Extract correction, x1_t, err from debug step for plotting
- Update tracking condition to use is_debug_enabled() method

* Move plotting logic from modeling_smolvla to eval_dataset script

Refactor to improve separation of concerns:

modeling_smolvla.py changes:
- Remove all plotting logic from sample_actions method
- Remove viz_xt_axs, viz_vt_axs, viz_x1t_axs parameters
- Remove matplotlib and RTCDebugVisualizer imports
- Remove viz_fig, viz_axs, denoise_step_counter instance variables
- Simplify denoising loop to only track data in rtc_processor

eval_dataset.py changes:

- Retrieve debug steps from tracker after inference
- Plot x_t, v_t, x1_t, correction, and error from tracker data
- Enable debug tracking (cfg.rtc.debug = True) for visualization
- Remove viz axes parameters from predict_action_chunk calls

modeling_rtc.py changes:
- Remove v_t from track() call (handled by user change)

Benefits:
- Cleaner modeling code focused on inference
- Evaluation script owns all visualization logic
- Better separation of concerns
- Tracker is single source of truth for debug data

* Refactor plotting loging

* fixup! Refactor plotting loging

* Improve visualization: separate correction plot and fix axis scaling

Changes:
- Create separate figure for correction data instead of overlaying on v_t

- Fix v_t chart vertical compression issue

Benefits:

* Add Quantile stats to LeRobotDataset (#1985)

* - Add RunningQuantileStats class for efficient histogram-based quantile computation
- Integrate quantile parameters (compute_quantiles, quantiles) into LeRobotDataset
- Support quantile computation during episode collection and aggregation
- Add comprehensive function-based test suite (24 tests) for quantile functionality
- Maintain full backward compatibility with existing stats computation
- Enable configurable quantiles (default: [0.01, 0.99]) for robust normalization

* style fixes, make quantiles computation by default to new datasets

* fix tests

* - Added DEFAULT_QUANTILES=[0.01, 0.10, 0.50, 0.90, 0.99] to be computed for each features instead of being chosen by the user
- Fortified tests.

* - add helper functions to reshape stats
- add missing test for quantiles

* - Add QUANTILE normalization mode to normalize the data with the 1st and 99th percentiles.
- Add QUANTILE10 normalization mode to normalize the data with the 10th and 90th percentiles.

* style fixes

* Added missing lisence

* Simplify compute_stats

* - added script `augment_dataset_quantile_stats.py` so that we can add quantile stats to existing v3 datasets that dont have quatniles
- modified quantile computation instead of using the edge for the value, interpolate the values in the bin

* rename pi0/pi05 files

* Remove open pi patch and use custom transformer branch for now

* renaming

* fix

* Revert "fix"

This reverts commit 1ea65730ac.

* fix naming

* feet(pi0/pi0.5): add pipeline (#2009)

* feat(processor): convert openpi model with processor

* TODO: Make test works

* fix(modeling_pi0openpi): update attention mask value and time scaling; improve task handling in tests

- Changed the attention mask value from `self.config.attention_mask_value` to a fixed value of `-2.3819763e38`.
- Updated time scaling in the `sample_noise` method to use a constant factor of `0.999` and an offset of `0.001`.
- Enhanced task handling in tests to ensure proper formatting and batch size consistency.
- Cleaned up commented-out test code for clarity.

* refactor(pi0): rename PI0OpenPIConfig and PI0OpenPIPolicy to PI0Config and PI0Policy

- Updated imports and references throughout the codebase to reflect the new naming convention.
- Introduced a new processor file for PI0 to handle pre-processing and post-processing steps.
- Adjusted tests to utilize the renamed classes, ensuring consistency and functionality.
- Enhanced clarity and maintainability by removing outdated naming conventions.

* refactor(pi05): rename PI0OpenPIPolicy to PI0Policy and update configuration

- Renamed `PI0OpenPIPolicy` to `PI0Policy` for consistency with naming conventions.
- Updated the `PI05OpenPIConfig` to include a new `tokenizer_max_length` attribute and changed the normalization mode for state from `MEAN_STD` to `QUANTILES`.
- Simplified model initialization in `PI05OpenPIPolicy` by removing unused `dataset_stats` parameter.
- Added a new processor class for `Pi05PrepareStateTokenizerProcessorStep` with `@dataclass` for improved readability.
- Introduced a test script to compare the integration of the PI0OpenPI policy with the original implementation, ensuring local testing compatibility.

* refactor(pi05): update imports and rename configuration classes

- Changed imports to reflect the new naming convention for PI05 configuration and policy classes.
- Renamed `PI05OpenPIConfig` to `PI05Config` and `PI05OpenPIPolicy` to `PI05Policy` for consistency.
- Introduced a new processor file for PI05, implementing pre-processing and post-processing steps.
- Updated tests to utilize the renamed classes, ensuring functionality and consistency across the codebase.

* update(pi05): increase tokenizer_max_length for improved processing

- Changed the `tokenizer_max_length` from 48 to 200 to enhance the model's capability in handling longer sequences.
- This adjustment aims to improve the overall performance and flexibility of the PI05 configuration.
