Summary

Builds on #90 (merged). Adds episode checks and the first validity metrics, a console summary of the report, and
parsing of every record the report reads.

Changes

  • Episode checks (correctness and camera streams) run before any metric. A failing episode is counted in
    correctness_pass_rate or image_stream_pass_rate and left out of the dataset metrics.
  • New metrics final_success_rate and action_rotation_error; baseline=True also computes a metric on the
    source dataset.
  • The console summary shows a verdict, the metrics by area with their source baseline and sample count, and what
    was not computed and why. With --gate, gated metrics are marked ✓ or ✗.
  • Records (the autodata entry, result file, attempt log) are parsed once against declared shapes in
    autodata_metrics/records.py; a malformed one is refused with the file and field named.
  • Annotation is timed from process start and records its mode; time_to_dataset is version 2.
  • Docs: the metrics page covers the checks, the summary and what the report trusts; the Franka workflow shows how
    to record and report metrics.

Testing

  • Unit tests pass, including generated tests over malformed records, gates and degenerate episodes.
  • Annotation, MimicGen and SkillGen end-to-end tests pass; the docs build passes with -W.

Summary by CodeRabbit

  • New Features
    • Added episode-level validation for finite values, aligned step lengths, valid rotations and action bounds, and camera-stream issues such as missing, black, or frozen frames.
    • Reports now show valid and total episode counts, summarize check failures with examples, and exclude failed episodes from dataset metrics.
    • Added correctness and image-stream pass rates, final task success rate, and commanded-rotation error metrics. Baseline-enabled metrics can show corresponding source values.
    • Reports now include per-metric gate verdicts and clearer summaries of errors, skipped metrics, and warnings. Invalid gate files and unreadable source datasets are rejected.
    • Annotation records now include mode and setup time. Dataset-generation timing metrics account for setup and automated annotation time; manual annotation time is reported separately.
  • Documentation
    • Added guidance on episode checks, metric reporting and interpretation, and workflows for generating and validating metric reports.

Generation, annotation and retargeting now record what dataset metrics
need, without computing any metric:

- Every producer records step_success from the task's success term.
  Generation also records the per-step EEF and commanded target poses,
  but not object poses, which annotation keeps for the source pool.
- Each exported dataset gets an autodata entry in env_args: run id,
  exported count, pose-action layout, robot joint names with simulator
  limits, and optional datasheet hardware_limits from the embodiment.
- --result_file adds a run block (run id, seed, revision, input
  digests, hardware, setup and generation time) and an attempt log, one
  line per attempt with its failure cause and algorithm extras.
- GenerationAlgorithm.attempt_extras() lets an algorithm report
  per-attempt facts; SkillGen reports its motion-planning time.
Metrics are plain functions registered with @Metric. Each declares the
evidence it requires (an HDF5 path, an env_args, run or attempt-log
field, or the source dataset); without it the report says which key is
missing instead of computing anything. A metric that raises is reported
as an error without hiding the others. The report refuses a dataset and
run record whose run ids or exported counts differ.

validate_dataset.py --report computes every registered metric, --metrics
loads more from a module, and --gate fails the command when a gated
metric is out of bounds, not applicable or at another version.

Built-in run metrics: generation success rate (stop-corrected, Wilson
interval), demos per GPU-hour, time to dataset, annotation pass rate,
and the failure-share and planning-time diagnostics.
- Each run writes its own attempt log, <stem>.<run_id>.attempts.jsonl,
  so rerunning with the same --result_file keeps earlier logs, and an
  interrupted rerun leaves the earlier result and its log consistent.
- A _failed dataset gets this run's autodata entry only when this run
  kept failed episodes, so one left by an earlier run is not relabelled.
- The e2e helper checks the logged successes against the result.
- Docs: only generated datasets have a result file and attempt log.
Each run now writes its own attempt log. The report reads the log named
by the result when the result belongs to the dataset's run; otherwise it
sets the result aside with a warning and reads the log named by the
dataset's run id, so an interrupted rerun is still reported and runs are
never mixed.
…extras

- Metric recording is off by default, so datasets and result files
  are unchanged unless --record_metric_inputs is given to generation,
  annotation or retargeting. It records the per-step poses and task
  success, the autodata entry and, with --result_file, the run block
  and attempt log.
- GenerationResult no longer has failure_cause; SkillGen reports
  planning_failed in its attempt extras, next to planning_time_s.
- metric_context() docstrings say what they record; the pose-action
  entry's columns key is now action_slice.
- Docs: the run linkage holds once the run completes.
…un metrics tests in CI

- The report marks a metric whose value is not a finite number as an
  error, and the gate counts a missing or non-numeric value as a
  violation.
- validate_dataset.py errors when --result_file, --source, --metrics,
  --gate or --report_file is given without --report.
- failure_share is replaced by planning_failure_rate, read from
  SkillGen's planning_failed attempt extra.
- CI runs autodata_tests/metrics/.
- Docs: metrics need --record_metric_inputs at recording time.
…s term

- With --record_metric_inputs, the per-step pose term is added to a
  custom --recorder_cfg too, unless it already records datagen info.
- Without a success term, step_success is not recorded instead of
  failing on the first step.
- Episode checks run before any metric: finite values, aligned
  per-step lengths, valid observed rotations, pose actions within
  their clip bound, and camera streams (one frame per step, no black
  frames, no frozen runs). An episode failing a check is counted in
  correctness_pass_rate or image_stream_pass_rate and left out of every
  dataset metric; the report lists the failures per check.
- final_success_rate: share of episodes whose task success holds at
  their last step.
- action_rotation_error: how far the commanded target rotations are
  from valid rotations.
- A metric declared with baseline=True is also computed on the source
  dataset, using the run's autodata entry and control step.
- Docs: the metrics page lists the checks, generated from their
  @check declarations.

Walkthrough

The metrics package adds episode checks and validity metrics, filters failed episodes from dataset metrics, and expands report and gate output. Annotation metadata records mode and setup time. The version 2 time-to-dataset metric uses these fields alongside generation time and applicable annotation time.

Changes: Episode validation and metrics

Layer / File(s) Summary
Check contracts and validity metrics
autodata_metrics/registry.py, autodata_metrics/evidence.py, autodata_metrics/validity.py, autodata_metrics/__init__.py, autodata_tests/metrics/test_validity.py
The registry adds check specifications and episode-scoped metric options. Evidence retains all episodes and exposes traversal helpers and camera paths. Checks cover arrays, poses, actions, and camera streams. Metrics report check pass rates, final success, and commanded-rotation error.
Report generation and gate evaluation
autodata_metrics/report.py, scripts/validate_dataset.py, autodata_tests/metrics/test_report.py, autodata_tests/e2e/test_*data_generation.py, autodata_tests/utils/utils.py, docs/_ext/autodata_doc_tools.py, docs/pages/references/metrics.rst, docs/pages/workflows/franka_cube_stack_mimicgen/*
Reports include valid-episode counts, check failures, and source metric baselines. Gate evaluation returns per-metric results, and console output includes metric and check details. Tests and documentation cover report generation and validation.
Annotation timing and viability metrics
scripts/annotate_demos.py, autodata_metrics/viability.py, autodata_tests/e2e/test_annotation.py, autodata_tests/metrics/test_viability.py, docs/pages/concepts/data_generator.rst
Annotation metadata records mode and setup time. The version 2 time-to-dataset metric includes setup and generation time, includes automatic annotation time, and reports other annotation time separately.

Merge Risk: Moderate · previous review 1b74d

Malformed camera streams can be skipped by the image-stream checks, so a dataset can show a falsely high pass rate. Separately, a malformed result or attempt-log file crashes the --report command with a traceback instead of a clean refusal. Both should be fixed before merge.

Explanation

The description has a Summary section and a Detailed description section, and the template's required headings are present. The Summary is a short one-liner that exceeds the template's 50-character limit, and it does not state the change in under 50 characters. The Detailed description covers the reason for the change only indirectly. It lists what changed in a bullet list, and it names the tests run. The impact of the change is not stated. The description also omits the 'Detailed description' prompts on reason and impact. Most of the required structure is present, so the check passes.

Full details: Docstring Coverage

Explanation

Docstring coverage is 66.10% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 59 functions across 17 files.

…JSON

- The report refuses a result whose attempt and success counts differ
  from its attempt log.
- Run and gate input checks raise ValueError, so they also hold under
  python -O.
- Non-finite numbers in a metric's details are reported as null.
- A dataset whose env_args are not a JSON object reads as having none.
- An empty metrics mapping computes no metrics instead of all of them.
- Docs: how the report treats a result from another run; the example
  metric gets its own name; joint-limit metrics are not mentioned yet.
- The end-to-end tests run the report through assert_ok_metrics.
…ble code

- No baseline metric reads the run's autodata entry or control step,
  so the source dataset is evaluated as it is.
- One parser of the @Metric and @check declarations builds both docs
  tables.
- Episode.datasets returns a list; the module constants sit together.
- When the result records the run's source, the report refuses a
  --source with a different SHA-256, so source-based metrics read the
  dataset the run started from.
- A gate entry whose min or max is not a finite number is an error
  instead of a bound that can never be violated.
- A gate bound must be an int or float that is finite; YAML booleans
  and mappings are errors instead of passing or failing the comparison.
- Docs: the source is verified only when the result file records it.

including all-zero poses, for validation by _rotation_errors.
- Line 43: Update the finite-value validation in `episode.datasets()` to scan

- The console summary leads with a verdict (valid episodes, computed
  and not-computed metrics, the gate), lists the computed metrics by
  area with their source baseline and what their sample counts, and
  groups the metrics that do not apply by what would make them apply.
  With --gate, gated metrics are marked met or failed.
- @Metric declares what a metric's sample count counts.
- Pass rates report which checks ran and which did not apply;
  valid_rotations no longer passes an episode that records no rotation.
- gate_results returns the result of every gated metric.
- Annotation records its mode and its setup time, timed from process
  start like generation. time_to_dataset version 2 counts annotation
  setup and keeps manual annotation time out of the total.

  steps show how to record and report metrics.

- one_frame_per_step fails an episode that lacks a camera stream other
  episodes record.
- finite reads floating-point arrays in chunks instead of whole.
- aligned_lengths fails an episode with no actions.
- valid_rotations checks every observed pose, all-zero ones included;
  only commanded targets skip all-zero placeholders.
- A rotation's error includes |det R - 1|, so reflections fail.
- assert_ok_metrics asserts that every episode passes the checks.

- aligned_lengths skips scalar datasets, and valid_rotations reads the
  last axis only of arrays that have one.
- action_rotation_error is not applicable to a target group without end
  effectors.
- The console summary leaves out an interval with a missing bound, shows
  every entry of a dict value without its primary entry, and a sample
  count that is not an integer makes its metric an error.
- time_to_dataset counts annotation time only when the record says it
  was automatic; other annotation time is reported apart.
… and gates

- A metric that returns something other than a Value, a nested dict,
  details that are not a mapping, or a non-integer sample count is an
  error row instead of breaking the report or its summary.
- Details and value keys are written as strings, so the report stays
  valid JSON.
- env_args that are not JSON read as empty.
- load_gate validates the gate file before the report is built and
  reads numbers YAML leaves as strings, such as 1e-3; a key on a value
  without entries fails the gate instead of raising.
- Not-computed hints name the absent attempt log or source before the
  algorithm, and a result file that does not exist is warned about.
- The report records the source dataset's checks, and the summary's
  title says how many source episodes were valid.
- A rate just below one shows as >99.9% rather than 100%.

Identify malformed camera streams as camera streams.

If every episode records a camera path as a three-dimensional or floating-point array, camera_paths is empty. All image checks then become not applicable, so the report can retain those episodes without flagging the invalid streams. Identify expected camera paths independently of a stream’s dtype and shape, then validate those properties per episode. Preserve the not-applicable result for a dataset with no cameras.

- Around line 45-46: Validate result records and attempt-log records at
ingestion, checking that each has the required fields and types before
downstream use; include the record path in every validation ValueError. Ensure
malformed inputs such as an empty result or a null attempt record are rejected
before check_same_run or field access.

- autodata_metrics/records.py declares the shapes of the autodata entry,
  the result file and its run block, and an attempt-log line. A record
  is parsed once where it is read; a missing field, a wrong type, a
  negative count or a number a float cannot hold is refused with an
  error naming the file and field, and absent or null optional fields
  are left out, so readers see a field well formed or not at all.
  Fields no metric reads are not checked.
- Run files that cannot be read, are not UTF-8 or nest too deeply are
  refused with the file named.
- Value checks itself when it is created, so a metric with a malformed
  Value is an error row and the report reads only well-formed values.
- A source merged or edited after annotation has its annotation record
  set aside, with a warning.
- The e2e helpers parse what generation and annotation write, so a
  producer that drifts from the shapes fails its test.
- Generated tests mutate every field of every record and gate with
  wrong values, and feed unreadable run files, asserting the report
  refuses or reports them and never raises; a corpus of degenerate
  episodes asserts no check raises.
- Docs: what the report trusts.

A few comments on various validity checks

Comment thread autodata_metrics/validity.py Resolved
- no_frozen_frames: a camera counts as frozen when it repeats one frame
  for 1 s of recorded time, converted with the dataset's dt and
  decimation, so the threshold no longer depends on the control rate.
  A dataset that records no control step skips the check.
- aligned_lengths: subtask signals must hold one entry per action. Each
  signal is counted by its entries, since sources store it as a
  (steps,) column or a (1, steps) row.
- valid_rotations: an observed pose not shaped (steps, 4, 4), or a root
  pose not shaped (steps, 7), fails the episode instead of being
  skipped.
