uv sync --locked validates the entire lockfile across all extras.
Since robomme depends on mani-skill which pins numpy<2.0, and the
base project requires numpy>=2.0, the full lockfile is unsatisfiable.
Switch to uv pip install -e ".[libero,smolvla]" which only resolves
the requested extras for the current Python version and platform,
avoiding the cross-extra numpy conflict entirely.

Security:
- Remove "Login to Hugging Face" step — it was a no-op (ephemeral
--rm container) that exposed the HF token via CLI argument in
docker inspect / /proc/*/cmdline. The eval step already
re-authenticates via env var.
Functional:
- Remove feat/benchmark-ci from push trigger branches (won't exist
post-merge).
Dockerfiles:
- Pin uv to 0.8.0 (was unpinned, fetching whatever latest ships).
- Add comment explaining the chmod +x ptxas workaround (Triton
packaging bug — ships ptxas without execute bit).
Scripts:
- parse_eval_metrics.py: add note that it runs on bare host and must
stay stdlib-only.
- parse_eval_metrics.py: add NaN guard for avg_sum_reward and eval_s
(was only guarding pc_success).

* fix(one shot load): adding metadata loading when reading from a dataset after writing
* refactor(one shot load): move metadata reload to ensure_readable() on LeRobotDatasetMetadata
Move the metadata reload from DatasetReader.load_and_activate() to a new
public ensure_readable() method on LeRobotDatasetMetadata, called from
LeRobotDataset._ensure_reader(). This places lifecycle management in the
right layer: metadata owns its readiness check, the dataset orchestrates
the write-to-read transition, and the reader stays clean.
Also adds a regression test using delta_timestamps to exercise the
meta.episodes access path in the create -> write -> finalize -> read flow.

The huggingface org restricts GHCR package creation via GITHUB_TOKEN,
causing 403 on cache export. Remove all registry caching and GHCR
login. The Dockerfile layer split (deps vs source) still helps when
the runner has a warm Docker daemon.

Docker Hub CI token can't push to new repos. GHCR works out of the

- Add GHCR login step (github.actor + GITHUB_TOKEN)

GHA cache is capped at 10GB per repo — a single CUDA + PyTorch +
benchmark image is ~8GB so the cache evicts before it's reused.

limit, layers persist until explicitly deleted, and shared across

The dep-install layer (uv sync) now only depends on pyproject.toml,

The task descriptions were never populated in metrics.json because
extract_task_descriptions.py was never invoked. The script exists and
parse_eval_metrics.py already looks for its output — the call was
simply missing from the workflow.
Appends the extraction step to the existing bash -c block (runs inside
the container where libero/metaworld is installed) so task_descriptions.json
is written to the eval-artifacts dir before docker cp copies it out.

- Add scripts/ci/extract_task_descriptions.py: runs inside the benchmark
Docker container (LIBERO/MetaWorld installed) after lerobot-eval and
writes task_descriptions.json mapping task keys to NL instructions.
LIBERO: uses libero.libero.benchmark to get suite.get_task(i).language.
MetaWorld: formats task name as human-readable label.
- Call extraction at the end of each eval bash-c (|| true so never fatal).
- parse_eval_metrics.py reads task_descriptions.json and includes it in
metrics.json so the health dashboard Space can label videos by task.

* 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.
Made-with: Cursor
* docs: update adding_benchmarks for async env changes

Made-with: Cursor
* 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.

* 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.
