For ImgEdit benchmarks, InferBench’s prompts are necessary. + +4. **VieScore**: InferBench’s SC+PQ prompts match the original VieScore design. Pruna’s uses improved explicit 0–10 scale prompts. + +5. **VLM Base**: Pruna now uses unified "Please answer yes or no." suffix for both Litellm and Transformers. diff --git a/pyproject.toml b/pyproject.toml index 9a43e26d..c6c6da8b 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -167,10 +167,8 @@ vllm = [ "ray", ] evaluation = [ - "pydantic>=2.0.0", + "outlines>1.2.0,<2.0.0", "litellm>=1.0.0", - "transformers>=4.40.0", - "accelerate>=0.20.0", ] stable-fast = [ "xformers>=0.0.30", diff --git a/src/pruna/evaluation/metrics/__init__.py b/src/pruna/evaluation/metrics/__init__.py index 66b6051b..32051277 100644 --- a/src/pruna/evaluation/metrics/__init__.py +++ b/src/pruna/evaluation/metrics/__init__.py @@ -15,24 +15,23 @@ from pruna.evaluation.metrics.registry import MetricRegistry # isort:skip from pruna.evaluation.metrics.aesthetic_laion import AestheticLAION +from pruna.evaluation.metrics.metric_alignment_score import AlignmentScoreMetric from pruna.evaluation.metrics.metric_cmmd import CMMD from pruna.evaluation.metrics.metric_dino_score import DinoScore from pruna.evaluation.metrics.metric_elapsed_time import LatencyMetric, ThroughputMetric, TotalTimeMetric from pruna.evaluation.metrics.metric_energy import CO2EmissionsMetric, EnergyConsumedMetric from pruna.evaluation.metrics.metric_evalharness import LMEvalMetric +from pruna.evaluation.metrics.metric_img_edit_score import ImageEditScoreMetric from pruna.evaluation.metrics.metric_memory import DiskMemoryMetric, InferenceMemoryMetric, TrainingMemoryMetric from pruna.evaluation.metrics.metric_model_architecture import TotalMACsMetric, TotalParamsMetric from pruna.evaluation.metrics.metric_pairwise_clip import PairwiseClipScore +from pruna.evaluation.metrics.metric_qa_accuracy import QAAccuracyMetric from pruna.evaluation.metrics.metric_sharpness import SharpnessMetric +from pruna.evaluation.metrics.metric_text_score import TextScoreMetric from pruna.evaluation.metrics.metric_torch import TorchMetricWrapper -from pruna.evaluation.metrics.metrics_vlm import ( - AlignmentScoreMetric, - ImageEditScoreMetric, - QAAccuracyMetric, - TextScoreMetric, - VieScoreMetric, - VQAMetric, -) +from pruna.evaluation.metrics.metric_viescore import VieScoreMetric +from pruna.evaluation.metrics.metric_vqa import VQAMetric +from pruna.evaluation.metrics.vlm_base import BaseVLM, LitellmVLM, TransformersVLM, get_vlm __all__ = [ "MetricRegistry", @@ -59,4 +58,8 @@ "QAAccuracyMetric", "TextScoreMetric", "VieScoreMetric", + "BaseVLM", + "LitellmVLM", + "TransformersVLM", + "get_vlm", ] diff --git a/src/pruna/evaluation/metrics/metric_alignment_score.py b/src/pruna/evaluation/metrics/metric_alignment_score.py new file mode 100644 index 00000000..1ecc9eca --- /dev/null +++ b/src/pruna/evaluation/metrics/metric_alignment_score.py @@ -0,0 +1,120 @@ +# Copyright 2025 - Pruna AI GmbH.

Yes/No" | -| **Text Score** | Short OCR prompt | Detailed OCR prompt | InferBench: longer, explicit format rules | -| **Img Edit Score** | Simple 0–10 rating | Full judge prompts from ImgEdit repo | InferBench: 5-point multi-criteria per edit type | -| **VieScore** | Two short prompts | Long SC + PQ prompts | InferBench: detailed rules, JSON output | -| **QA Accuracy** | Generic "What is in this image?" | Benchmark-specific questions | Different use cases | -| **VLM Base (score)** | Litellm: "Answer Yes or No" / Transformers: "Question: X Answer:" | Generation + logprobs fallback | Response format differs | - ---- - -## 1. Alignment Score - -### Pruna -- **Question**: `Does this image show "{prompt}"? Answer Yes or No.` -- **Expected answer**: `Yes` -- **Scope**: Single prompt–image alignment per sample -- **Source**: `metric_alignment_score.py`, `metric_vqa.py` (same logic) - -### InferBench -- **Questions**: From OneIG JSON (e.g. `anime.json`, `human.json`, `object.json`) -- **Template**: `{question}. Only answer 'Yes' or 'No'. Do not answer anything else.` -- **Examples**: "Are there boys?", "Are there four boys?", "Is there a nun?", etc. -- **Dependencies**: Parent–child question graph; child scores set to 0 if parent is No -- **Scope**: 9–20 questions per image, dependency-aware aggregation -- **Source**: `alignment_score.py`, `oneig.py` (benchmark) - ---- - -## 2. VQA (Visual Question Answering) - -### Pruna -- Same as Alignment Score: `Does this image show "{prompt}"? Answer Yes or No.` -- Used for both `alignment_score` and `vqa` metrics - -### InferBench -- **Template**: `Does this figure show "{prompt}"? Please answer yes or no.` -- **Expected answer**: `Yes` -- **Difference**: "figure" vs "image"; "Please answer yes or no" vs "Answer Yes or No" -- **Source**: `vqa.py` - ---- - -## 3. Text Score (OCR) - -### Pruna -- **Prompt**: `Extract all text from this image. If no text, say 'No text'.` -- **Output use**: Binary check (no text → score 10.0, else 0.0) — *Note: Pruna text_score appears to use edit distance logic elsewhere; this prompt is for OCR extraction* -- **Source**: `metric_text_score.py` - -### InferBench -- **Prompt**: - ``` - Extract all text visible in this image. Include logos, stylized fonts, handwritten text, and non-standard typography. - Return only the extracted text, exactly as it appears—no preamble, explanation, or markdown. - Preserve words, numbers, punctuation, and spacing. If no text is recognized, reply with exactly: No text recognized - ``` -- **Post-processing**: Hallucination removal ("addCriterion", "No text recognized"), Levenshtein vs ground truth, word accuracy -- **Source**: `text_score.py` - ---- - -## 4. Image Edit Score - -### Pruna -- **Question**: `Rate 0-10: Does this image show "{prompt}"? Reply with a number.` -- **Input**: Single edited image + prompt -- **Output**: 0–10 score, normalized to [0, 1] -- **Source**: `metric_img_edit_score.py` - -### InferBench -- **Input**: Original image + edited image + edit instruction -- **Judge prompts**: Fetched from ImgEdit repo (`prompts.json`) per edit type (replace, add, remove, adjust, style, extract, background, compose) -- **Format**: Long multi-criteria prompts (5-point scale): - - Prompt Compliance (1–5) - - Visual Naturalness / Seamlessness (1–5) - - Physical & Detail Integrity (1–5) -- **Output**: Average of 3 scores, parsed from `"Prompt Compliance: N\nVisual Naturalness: N\n..."` format -- **Source**: `img_edit_score.py`, `img_edit.py` (benchmark), external `prompts.json` - ---- - -## 5. VieScore - -### Pruna -- **Semantic**: `Rate 0-10: Does this image show "{prompt}"?` -- **Quality**: `Rate 0-10: How natural is this image? Any artifacts?` -- **Aggregation**: `sqrt(semantic * quality) / 10` -- **Source**: `metric_viescore.py` - -### InferBench -- **SC (Semantic/Compliance)**: Long prompt with rules for editing success + overediting - - Two images (original + edited) - - `score1` = editing success (0–10), `score2` = overediting (0–10) - - Output: `[score1, score2]` -- **PQ (Perceptual Quality)**: Long prompt for naturalness + artifacts - - Single image - - `naturalness` (0–10), `artifacts` (0–10) - - Output: `[naturalness, artifacts]` -- **Aggregation**: `min(SC_scores)`, `min(PQ_scores)`, `overall = sqrt(SC * PQ)` -- **Context**: "You are a professional digital artist..." + JSON output format -- **Source**: `viescore.py` - ---- - -## 6. QA Accuracy - -### Pruna -- **Question**: `What is in this image? Answer:` -- **Scoring**: 1.0 if non-empty response, else 0.0 -- **Use**: Generic image understanding check -- **Source**: `metric_qa_accuracy.py` - -### InferBench -- **Questions**: From GenEval metadata (e.g. "Does the image show at least one red apple?", "Does the image show exactly 3 cats?") -- **Template**: `{question} Please answer yes or no.` -- **Expected answers**: `Yes` for all (benchmark-specific) -- **Scoring**: Accuracy over N questions, n_correct, n_incorrect -- **Source**: `qa_accuracy.py`, `geneval.py` (benchmark) - ---- - -## 7. VLM Base Layer (Score Method) - -### Pruna – LitellmVLM & TransformersVLM -- **Prompt**: `{question} Please answer yes or no.` -- **Scoring**: `1.0 if answer.lower() in response else 0.0` -- **Scoring**: Same substring check -- **Source**: `vlm_base.py` line 371 - -### InferBench – OpenAIAPIVLM -- **Scoring**: Prefers logprobs (Yes/No token probabilities) when available -- **Fallback**: Generation + substring check ("yes"/"no" in response) -- **No prompt suffix**: Question passed as-is; metrics add their own suffix -- **Source**: `api_vlm_base.py` - ---- - -## Recommendations - -1. **Alignment / VQA**: InferBench’s multi-question + dependency setup is more detailed; Pruna’s single-question version is simpler. For OneIG-style benchmarks, InferBench’s approach is required. - -2. **Text Score**: InferBench’s OCR prompt is more explicit and robust; Pruna now uses InferBench-style OCR prompt and supports ground-truth edit distance when gt contains text_content. - -3. **Img Edit Score**: InferBench uses full ImgEdit judge prompts; Pruna uses an improved single 0–10 rating with explicit scale instructions. For ImgEdit benchmarks, InferBench’s prompts are necessary. - -4. **VieScore**: InferBench’s SC+PQ prompts match the original VieScore design. Pruna’s uses improved explicit 0–10 scale prompts. - -5. **VLM Base**: Pruna now uses unified "Please answer yes or no." suffix for both Litellm and Transformers.

Replaced YesNoAnswer and ScoreOutput with VQAnswer and FloatOutput in multiple metric classes for consistency in structured outputs. - Enhanced the metric_vlm_utils.py file by introducing get_answer_from_response and get_text_from_response functions for better response handling. - Updated the TextScoreMetric to accept List[str] for ground truth, improving flexibility in input types. - Adjusted the update method in the test suite to accommodate new metric requirements and ensure compatibility with structured outputs. --- .../metrics/metric_alignment_score.py | 8 +- .../metrics/metric_img_edit_score.py | 8 +- .../evaluation/metrics/metric_qa_accuracy.py | 8 +- .../evaluation/metrics/metric_text_score.py | 64 +++------- .../evaluation/metrics/metric_viescore.py | 8 +- .../evaluation/metrics/metric_vlm_utils.py | 120 ++++++++++++++---- src/pruna/evaluation/metrics/metric_vqa.py | 8 +- src/pruna/evaluation/metrics/vlm_base.py | 27 +++- tests/evaluation/test_vlm_metrics.py | 40 +++++- 9 files changed, 179 insertions(+), 112 deletions(-) diff --git a/src/pruna/evaluation/metrics/metric_alignment_score.py b/src/pruna/evaluation/metrics/metric_alignment_score.py index 4ff89a1d..0b00fa6d 100644 --- a/src/pruna/evaluation/metrics/metric_alignment_score.py +++ b/src/pruna/evaluation/metrics/metric_alignment_score.py @@ -23,7 +23,7 @@ from pruna.engine.utils import set_to_best_available_device from pruna.evaluation.metrics.metric_stateful import StatefulMetric -from pruna.evaluation.metrics.metric_vlm_utils import YesNoAnswer, _process_images +from pruna.evaluation.metrics.metric_vlm_utils import VQAnswer, _process_images from pruna.evaluation.metrics.registry import MetricRegistry from pruna.evaluation.metrics.result import MetricResult from pruna.evaluation.metrics.utils import ( @@ -100,11 +100,7 @@ def __init__( use_outlines=use_outlines, **(vlm_kwargs or {}), ) -

Thu, 19 Mar 2026 20:24:28 +0100 Subject: [PATCH 26/60] feat(metrics): introduce OneIGTextScoreMetric and enhance TextScoreMetric - Added OneIGTextScoreMetric for OCR-based composite scoring, providing a higher-is-better metric. - Updated TextScoreMetric to include descriptive registry aliases and improved docstring clarity. - Enhanced initialization parameters for both metrics to support better configuration and compatibility. - Added tests for OneIGTextScoreMetric to validate functionality and ensure correct behavior with ground truth comparisons. ---

TransformersVLM._generate_standard: model.generate() returns the full input+output sequence; slicing output[0][input_len:] decodes only the new tokens, preventing prompt text from appearing in the VLM response. 2. OneIG Text_Rendering text_content: was using row_class ('PPT generation', 14 chars) as OCR ground truth, making empty-OCR text_score spuriously 0.86. Now extracts all quoted strings from the prompt for Text_Rendering rows, giving a ~236-char ground truth so empty OCR correctly scores 0.0. 3. vlm_benchmark_helpers._safe_json: bytes objects (source_image_bytes for editing benchmarks) fell through to str(obj) producing megabyte-long repr strings in JSON records. Now serialized as {"bytes_len": N}.

Fine-grained art styles such as "3d rendering" can have fewer than 4 samples, which made the nightly CI fail deterministically when assert len(prompts) == 4 was evaluated. 2. test_benchmark_category_filter: relax `assert len(prompts) == 4` to `assert 1 <= len(prompts) <= 4` so category-filtered datasets with a small number of samples do not fail the test.

This update lays the groundwork for more robust image editing evaluations and metric calculations. --- src/pruna/data/datasets/prompt.py | 233 +++++++----- src/pruna/data/datasets/text_generation.py | 8 +- src/pruna/evaluation/benchmarks.py | 47 +-- .../metrics/metric_alignment_score.py | 41 +-- .../metrics/metric_img_edit_score.py | 39 +- .../metrics/metric_oneig_reasoning.py | 7 + .../evaluation/metrics/metric_qa_accuracy.py | 45 ++- .../evaluation/metrics/metric_vie_score.py | 197 ++++++---- .../evaluation/metrics/metric_vlm_base.py | 103 ++++++ src/pruna/evaluation/metrics/metric_vqa.py | 44 +-- src/pruna/evaluation/metrics/registry.py | 7 + .../models/bidirectional_llama.py | 17 +- .../evaluation/metrics/viescore_prompts.py | 72 ++++ src/pruna/evaluation/metrics/vlm_base.py | 345 +++++++++++++++--- src/pruna/evaluation/metrics/vlm_utils.py | 92 ++++- src/pruna/evaluation/vlm_benchmark_helpers.py | 93 ++++- tests/data/test_datamodule.py | 7 + tests/evaluation/test_oneig_alignment.py | 17 + tests/evaluation/test_oneig_reasoning.py | 12 + tests/evaluation/test_vlm_metrics.py | 174 ++++++++- 20 files changed, 1244 insertions(+), 356 deletions(-) create mode 100644 src/pruna/evaluation/metrics/metric_vlm_base.py create mode 100644 src/pruna/evaluation/metrics/viescore_prompts.py diff --git a/src/pruna/data/datasets/prompt.py b/src/pruna/data/datasets/prompt.py index 3b28311f..b18d03d4 100644 --- a/src/pruna/data/datasets/prompt.py +++ b/src/pruna/data/datasets/prompt.py @@ -12,6 +12,7 @@ # See the License for the specific language governing permissions and # limitations under the License. +from pathlib import Path from typing import Literal, Tuple, get_args from datasets import Dataset, load_dataset @@ -133,17 +134,10 @@ def _warn_ignored_benchmark_seed(seed: int | None, *, dataset: str) -> None: def _oneig_alignment_language_zh(row: dict) -> bool: """Return True when the official Q_D file for this row should use the ``*_zh`` graphs.""" - row_category = row.get("category", "") - if row_category == "Multilingualism": + if row.get("category", "") == "Multilingualism": return True lang = row.get("language") or row.get("lang") - if isinstance(lang, str) and lang.lower() in {"zh", "zh-cn", "zh_cn", "chinese", "cn"}: - return True - if row.get("prompt_zh"): - return True - prompt = row.get("prompt") - prompt_en = row.get("prompt_en") - return bool(prompt and not (isinstance(prompt_en, str) and prompt_en.strip())) + return isinstance(lang, str) and lang.lower() in {"zh", "zh-cn", "zh_cn", "chinese", "cn"} def _oneig_qd_prefix(row: dict) -> str: @@ -203,18 +197,21 @@ def _to_oneig_record( is_text_rendering = row_category in ("Text_Rendering", "Text Rendering") if is_text_rendering and text: import re as _re + quoted = _re.findall(r'"([^"]+)"', text) text_content: str | None = " ".join(quoted) if quoted else (row_class if row_class != "None" else None) else: text_content = row_class if row_class != "None" else None + questions = {k: v for k, v in q_info.get("questions", {}).items() if v is not None} + dependencies = {k: v for k, v in q_info.get("dependencies", {}).items() if v is not None} return { "text": text, "subset": "Text_Rendering" if is_text_rendering else row_category, "text_content": text_content, "category": row_category, "class": row_class, - "questions": q_info.get("questions", {}), - "dependencies": q_info.get("dependencies", {}), + "questions": questions, + "dependencies": dependencies, "reasoning_gt_answer": reasoning_gt_answer, } @@ -471,6 +468,72 @@ def setup_genai_bench_dataset() -> Tuple[Dataset, Dataset, Dataset]: return ds.select([0]), ds.select([0]), ds +def ensure_imgedit_benchmark_images_extracted() -> Path: + """ + Download ``Benchmark.tar`` (if needed), extract it, and return the ``singleturn`` folder. + + Returns + ------- + Path + ``Benchmark/singleturn`` directory whose files are addressed by ``image_id``. + + Raises + ------ + RuntimeError + If the archive cannot be downloaded or extracted. + """ + import tarfile + + from huggingface_hub import hf_hub_download + + tar_path = Path(hf_hub_download(repo_id="sysuyy/ImgEdit", filename="Benchmark.tar", repo_type="dataset")) + extract_dir = tar_path.parent / "imgedit_singleturn" + candidate = extract_dir / "Benchmark" / "singleturn" + if not candidate.is_dir() or not any(candidate.iterdir()): + extract_dir.mkdir(parents=True, exist_ok=True) + with tarfile.open(tar_path, "r") as tar: + tar.extractall(path=extract_dir) + if not candidate.is_dir() or not any(candidate.iterdir()): + raise RuntimeError(f"ImgEdit: failed to extract Benchmark.tar to {candidate}") + return candidate + + +def load_imgedit_source_image_bytes(image_id: str, *, image_folder: Path | None = None) -> bytes: + """ + Read one ImgEdit source image as JPEG bytes (RGB). + + Parameters + ---------- + image_id : str + Path relative to the singleturn folder (from the official ``basic_edit.json`` ``id``). + image_folder : Path | None, optional + ``Benchmark/singleturn`` directory;
