OmniDocBench evaluation helper

Help community users run OmniDocBench reproducibly. Prefer a practical, path-specific workflow over generic setup advice:

1. Validate GT/prediction paths and runtime access.
2. Generate an isolated config using stable container paths.
3. Run python pdf_validation.py --config ... in Docker when possible.
4. Parse *_metric_result.json, *_run_summary.json, *_stage_execution.json, and *_runtime_environment.json.
5. Report scores, output paths, and any warnings that affect score credibility.

Be concise for simple questions, but include copy-paste commands when the user gives paths.

What to ask for

Ask only for missing details that affect commands or config:

• Deployment mode: Docker, conda/source, or remote SSH. Recommend Docker when CDM is needed.
• Evaluation type: default to end2end for OmniDocBench JSON + page markdown predictions.
• Paths:
  • ground-truth JSON, commonly OmniDocBench.json with exact capitalization on Linux
  • prediction markdown directory, often a nested markdown/ folder such as .../mineru/markdown
  • output directory, or permission to create a timestamped output directory
• Whether CDM is required.
• CPU/RAM or node size if the user mentions slowness, OOM, or cluster execution.

If the user explicitly asks you to run a job on a remote host and provides an SSH command, treat that as authorization for that host/path scope. Avoid destructive operations: do not delete, overwrite, or chmod shared data/results.

Key facts

• Entrypoint: python pdf_validation.py --config <config_path>.
• Default config: configs/end2end.yaml.
• Package: omnidocbench-eval, Python >=3.10,<3.12.
• Recommended Docker image: ghcr.io/zeng-weijun/omnidocbench-eval:repro-ubuntu2204.
• CDM depends on TeX Live/CJK, ImageMagick PDF read/write, and Ghostscript. Docker avoids most CDM dependency failures.
• Worker keys:
  • dataset.match_workers: page matching
  • metrics.display_formula.cdm_workers: CDM rendering/comparison, memory-heavy
  • metrics.table.teds_workers: table TEDS
• Worker rule: on 4 CPU / 8 GB, use 2 for match/CDM/TEDS; if unstable, use 1. Do not keep README default 13 on small nodes.

Input validation before running

Always validate before launching a long Docker evaluation. For remote runs, execute this on the remote host via SSH.

GT=/path/to/OmniDocBench.json
PRED=/path/to/prediction/markdown

test -f "$GT" && echo "GT_OK=$GT" || echo "GT_MISSING=$GT"
test -d "$PRED" && echo "PRED_OK=$PRED" || echo "PRED_MISSING=$PRED"
[ -f "$GT" ] && wc -c "$GT"
[ -d "$PRED" ] && echo "md_count=$(find "$PRED" -maxdepth 1 -name '*.md' | wc -l)"
[ -d "$PRED" ] && echo "empty_md=$(find "$PRED" -maxdepth 1 -name '*.md' -empty | wc -l)"
[ -d "$PRED" ] && find "$PRED" -maxdepth 1 -name '*.md' | sort | head -5
nproc
free -h || true

Interpretation:

• Full OmniDocBench v1.6 has 1651 pages. md_count should usually be close to 1651 for a full run.
• md_count=0 usually means the user passed a parent directory instead of the actual markdown/ directory.
• empty_md > 0 is not fatal, but report it because empty predictions lower scores.
• Linux paths are case-sensitive: OmniDocBench.json and omnidocbench.json differ. If GT is missing, check nearby JSON filenames before concluding the data is absent.

Docker workflow

Use Docker when possible, especially for CDM.

Check Docker access

DOCKER=docker
if ! docker ps >/dev/null 2>&1; then
  if sudo -n docker ps >/dev/null 2>&1; then
    DOCKER="sudo -n docker"
  else
    echo "Docker daemon is not accessible by docker or sudo -n docker"
    exit 4
  fi
fi
$DOCKER --version

Use sudo -n docker only when the user is authorized on that host. Do not try interactive sudo in an automated workflow.

Local end2end command

Use stable container paths and write a custom config inside the container. This avoids editing the repository and keeps host paths out of YAML.

GT=/abs/path/to/OmniDocBench.json
PRED=/abs/path/to/prediction/markdown
OUT=/abs/path/to/output_dir
WORKERS=4   # use 2 on 4CPU/8G; use 1 if CDM OOMs
IMAGE=ghcr.io/zeng-weijun/omnidocbench-eval:repro-ubuntu2204

fi

      teds_workers: ${WORKERS}
    reading_order:

    timeout_fallback_order_penalty: 0.10
EOF
python pdf_validation.py --config configs/custom_end2end.yaml 2>&1 | tee /workspace/result/eval.log"

If CDM is not needed, remove CDM from display_formula.metric and remove cdm_workers. This avoids TeX/ImageMagick/Ghostscript dependency failures, but the final report will not include Formula CDM.

Remote SSH / H-cluster workflow

When the user provides an SSH command, run the same validation and Docker workflow on the remote host. Use a heredoc remote script to avoid nested quoting bugs.

ssh -CAXY user@host 'bash -s' <<'REMOTE'
set -euo pipefail

REMOTE

Practical H-cluster lessons from a real MinerU v1.6 run:

• ssh -CAXY may print X11 warnings such as No xauth data; they are harmless for CLI evaluation.
• Docker may be installed but inaccessible through the daemon socket. Check docker ps; if it fails and sudo -n docker ps works, use sudo -n docker for the run.
• Record the output directory in /tmp/omnidocbench_latest_out.txt or a user-specific variant so it can be recovered after disconnection.
• GT capitalization matters: /.../OmniDocBench.json worked where lowercase omnidocbench.json did not.
• MinerU predictions may live in a nested markdown/ directory. Passing the parent directory can produce zero or inflated markdown counts.
• For 4CPU/8G with CDM, start with workers 2; use 1 if unstable.

Bundled helper scripts

This skill includes scripts that can be copied into the repo or run from the skill directory:

• scripts/generate_end2end_config.py: generate an end2end YAML.
• scripts/parse_results.py: parse a result directory and print a compact score/validation report.

Example:

python scripts/generate_end2end_config.py \
  --gt ./gt/OmniDocBench.json \
  --pred ./data_md/predictions \
  --out configs/custom_end2end.yaml \
  --workers 2

python scripts/parse_results.py /path/to/result_dir

Use --no-cdm with generate_end2end_config.py to omit CDM and cdm_workers.

Conda/source workflow

Use only when Docker is unavailable or the user needs to modify OmniDocBench code.

conda create -n omnidocbench python=3.10 -y
conda activate omnidocbench
pip install -e .
python -c "from src.core.pipeline import run_config_file; print('OK')"

For CDM in source installs, verify:

pdflatex --version | head -2
kpsewhich CJK.sty && kpsewhich c70gkai.fd
gs --version
magick --version | head -2
python -m pytest tools/test_environment_and_smoke.py::TestEnvironmentVersions -v -s

If ImageMagick blocks PDF read/write, adjust the ImageMagick 7 policy.xml. Prefer Docker instead when possible.

Config guidance

End2end

Use dataset_name: end2end_dataset, OmniDocBench JSON as ground_truth.data_path, and page-level markdown files as prediction.data_path. Use match_method: quick_match unless the user has a specific reason not to.

Prediction filenames should correspond to page image names with .jpg/.png replaced by .md. Some code paths also accept .mmd, but .md is the community-standard expectation.

md2md

Use md2md when both ground truth and prediction are markdown directories:

dataset:
  dataset_name: md2md_dataset
  ground_truth:
    data_path: /path/to/gt_mds
    page_info: /path/to/OmniDocBench.json
  prediction:
    data_path: /path/to/pred_mds
  match_method: quick_match

page_info enables page-level attributes and filtering.

Single-module recognition and detection

For formula/text/table recognition, the JSON usually contains both ground-truth and prediction fields; set prediction.data_key to the model field such as pred.

For layout/formula detection, ask for prediction JSON box schema and category names before writing pred_cat_mapping.

Result parsing and validation

After a successful run, list result files. Key files usually include:

• *_metric_result.json: raw metric data and attribute breakdowns
• *_run_summary.json: notebook-style summary and overall_notebook
• *_stage_execution.json: page count, worker counts, timeout/error/exception counts
• *_runtime_environment.json: Python/system/TeX/ImageMagick/Ghostscript details
• eval.log: full console log

Extract and report these fields:

overall = run_summary.notebook_metric_summary.overall_notebook
text_edit = metric_result.text_block.all.Edit_dist.ALL_page_avg
formula_cdm = metric_result.display_formula.page.CDM.ALL * 100
formula_edit = metric_result.display_formula.all.Edit_dist.ALL_page_avg
table_teds = metric_result.table.page.TEDS.ALL * 100
table_teds_structure = metric_result.table.page.TEDS_structure_only.ALL * 100
table_edit = metric_result.table.all.Edit_dist.ALL_page_avg
reading_order_edit = metric_result.reading_order.all.Edit_dist.ALL_page_avg

Also report validation counters:

• input prediction count and empty markdown count, if checked
• stage_execution.page_match.page_count
• stage_execution.page_match.fallbacks.quick_match_timeout.count
• stage_execution.metrics.display_formula.CDM.sample_count, timeout_case_count, error_case_count, exception_case_count
• stage_execution.metrics.table.TEDS.sample_count, timeout_case_count, error_case_count, exception_case_count
• runtime environment for TeX/CJK, ImageMagick, and Ghostscript

A clean run has CDM/TEDS timeout/error/exception counts equal to zero. Nonzero quick_match_timeout is a warning, not automatically a failed run.

Final report template

Use this structure after running evaluation:

## Result paths
- Output dir: `...`
- Metric JSON: `.../*_metric_result.json`
- Run summary: `.../*_run_summary.json`
- Stage execution: `.../*_stage_execution.json`
- Runtime environment: `.../*_runtime_environment.json`

## Scores
| Metric | Score |
|---|---:|
| Overall | **95.651953** |
| Text Edit Distance ↓ | **0.036843** |
| Formula CDM ↑ | **97.076037** |
| Formula Edit Distance ↓ | **0.093306** |
| Table TEDS ↑ | **93.564123** |
| Table TEDS Structure Only ↑ | **96.123305** |
| Table Edit Distance ↓ | **0.063565** |
| Reading Order Edit Distance ↓ | **0.125134** |

## Validation
- pages: 1651
- prediction md files: 1651, empty: 2
- quick_match_timeout_count: 2
- CDM samples/timeouts/errors/exceptions: 2352 / 0 / 0 / 0
- TEDS samples/timeouts/errors/exceptions: 665 / 0 / 0 / 0
- runtime: TeX Live 2025, ImageMagick 7.1.1-47, Ghostscript 9.55.0, CJK ok

Mention empty prediction files by name if there are only a few.

Troubleshooting playbook

• GT missing: check OmniDocBench.json capitalization and parent directory.
• Prediction count zero: use the actual page-level markdown folder, not the parent.
• Prediction count too high: parent directory may contain multiple model outputs; use the exact model markdown/ folder.
• Docker permission denied: try sudo -n docker; if that fails, ask for Docker group/sudo setup.
• CDM OOM or hang: reduce all workers, especially cdm_workers; on 4CPU/8G use 2, then 1.
• ImageMagick PDF policy error: Docker should avoid it; in source installs, allow PDF read/write in ImageMagick 7 policy.xml.
• pdflatex/kpsewhich/CJK missing: use Docker or install TeX Live 2025 and CJK resources.
• latexmlc unavailable: not necessarily fatal for standard end2end HTML-table evaluation; report only if the chosen table pipeline requires LaTeX-to-HTML conversion.

Safety and execution guidance

• Ask before starting long Docker pulls or evaluations unless the user explicitly says to run them.
• On remote/shared systems, create new timestamped output directories; do not overwrite or delete existing results.
• Use read-only mounts for GT and prediction inputs (:ro). Mount only the output directory writable.
• If running in the background, tell the user the task ID and output path, then parse results when complete.
