"""Extract natural-language task descriptions for a benchmark suite.
|
|
|
|
Runs inside the benchmark Docker container (where the env library is installed)
|
|
immediately after lerobot-eval, writing a JSON file that parse_eval_metrics.py
|
|
picks up and embeds in metrics.json.
|
|
|
|
Output format: {"<suite>_<task_idx>": "<nl instruction>", ...}
|
|
|
|
Usage:
|
|
python scripts/ci/extract_task_descriptions.py \\
|
|
--env libero --task libero_spatial \\
|
|
--output /tmp/eval-artifacts/task_descriptions.json
