The simulator: - Implements /v1/chat/completions endpoint with OpenAI-compatible format - Loads AIME dataset from HuggingFace with local caching - Uses Levenshtein distance for intelligent question matching - Supports configurable success rate for correct/wrong answer generation - Provides debug logging for troubleshooting Also includes test scripts and documentation for testing and understanding the simulator functionality. --- examples/llama-eval/llama-eval-discussion.md | 116 ++++++++ .../llama-eval/llama-server-simulator-plan.md | 184 ++++++++++++ examples/llama-eval/llama-server-simulator.py | 267 ++++++++++++++++++ examples/llama-eval/simulator-summary.md | 135 +++++++++ examples/llama-eval/test-cache.sh | 43 +++ examples/llama-eval/test-simulator.sh | 93 ++++++ 6 files changed, 838 insertions(+) create mode 100644 examples/llama-eval/llama-eval-discussion.md create mode 100644 examples/llama-eval/llama-server-simulator-plan.md create mode 100755 examples/llama-eval/llama-server-simulator.py create mode 100644 examples/llama-eval/simulator-summary.md create mode 100755 examples/llama-eval/test-cache.sh create mode 100755 examples/llama-eval/test-simulator.sh diff --git a/examples/llama-eval/llama-eval-discussion.md b/examples/llama-eval/llama-eval-discussion.md new file mode 100644 index 0000000000..340345a8c5 --- /dev/null +++ b/examples/llama-eval/llama-eval-discussion.md @@ -0,0 +1,116 @@ +# llama-eval Implementation Discussion + +## Overview +Discussion about implementing a lean evaluation tool for llama.cpp based on ggerganov's feedback in PR #18892. + +## Key Requirements from ggerganov + +### 1.

New `_extract_answer_regex()` method extracts answers using configured patterns + - Supports case-insensitive matching + - Returns first valid match found + - Handles both single values and multiple matches + +3. **LLM-Based Judge** + - New `_grade_llm()` method for generic answer extraction + - Includes problem statement in prompt for context + - Configurable server URL (defaults to main server) + - Configurable model name (defaults to main model) + - Case-insensitive comparison + - Returns extracted answer for display + +4. **Response Truncation** + - New `_truncate_response()` method keeps only last 2-3 lines + - Applied before grading to focus on final answer section + +5. **CLI Grader Update** + - Now also returns extracted answer + - Returns None if grading fails + +6. **Display Updates** + - Progress table shows extracted answer instead of full response + - Verbose mode shows full response plus extracted answer + +7. **New CLI Arguments** + - `--grader-type`: Added "llm" option + - `--judge-server`: Separate server for LLM judge + - `--judge-model`: Separate model for LLM judge + +**Testing Results:** +- ✅ Regex grader extracts answers correctly from various formats +- ✅ LLM judge can extract answers with problem context +- ✅ Response truncation focuses grading on final answer +- ✅ Case-insensitive matching works for both regex and LLM grader +- ✅ Judge model and server configuration propagate correctly +- ✅ Progress table shows extracted answers instead of full responses + +**Key Technical Decisions:** +- Judge parameters set once during Grader construction (not on each call) +- LLM judge prompt includes problem statement for better extraction +- Response truncation to last 2-3 lines focuses grading on final answer +- Case-insensitive comparison for more flexible matching +- Judge configuration propagates through Processor to Grader +- Display shows extracted answer for cleaner output + +**Refactoring:** +- Removed judge parameters from `grade()` method calls +- Added `judge_server_url` and `judge_model_name` to Grader class +- Updated `_grade_llm()` to use instance variables instead of parameters +- Simplified Processor initialization to pass judge config to grader +- Updated startup info to show judge server and model diff --git a/examples/llama-eval/llama-server-simulator-plan.md b/examples/llama-eval/llama-server-simulator-plan.md index 0099894887..ac7dfad060 100644 --- a/examples/llama-eval/llama-server-simulator-plan.md +++ b/examples/llama-eval/llama-server-simulator-plan.md @@ -176,9 +176,14 @@ AIME dataset loaded: 1000 questions -

- `--grader-type`: Added "llm" option - - `--judge-server`: Separate server for LLM judge - - `--judge-model`: Separate model for LLM judge - -**Testing Results:** -- ✅ Regex grader extracts answers correctly from various formats -- ✅ LLM judge can extract answers with problem context -- ✅ Response truncation focuses grading on final answer -- ✅ Case-insensitive matching works for both regex and LLM grader -- ✅ Judge model and server configuration propagate correctly -- ✅ Progress table shows extracted answers instead of full responses - -**Key Technical Decisions:** -- Judge parameters set once during Grader construction (not on each call) -- LLM judge prompt includes problem statement for better extraction -- Response truncation to last 2-3 lines focuses grading on final answer -- Case-insensitive comparison for more flexible matching -- Judge configuration propagates through Processor to Grader -- Display shows extracted answer for cleaner output - -**Refactoring:** -- Removed judge parameters from `grade()` method calls -- Added `judge_server_url` and `judge_model_name` to Grader class -- Updated `_grade_llm()` to use instance variables instead of parameters -- Simplified Processor initialization to pass judge config to grader -- Updated startup info to show judge server and model - -### llama-eval-new.py GSM8K Dataset Support - -**Changes Made:** -1. **GSM8K Dataset Integration** - Added support for GSM8K dataset alongside AIME - - Created `Gsm8kDataset` class with proper answer extraction logic - - GSM8K uses `"question"` field instead of `"problem"` field - - GSM8K answer field contains full reasoning with `####` prefix - - Extracts numeric answer from answer field during initialization - - Uses same regex grader pattern as AIME (`\b(\d+)\b`) - -2. **Dataset Type Configuration** - Added dataset selection support - - Added `--dataset` CLI argument with choices `aime` and `gsm8k` - - Updated `Processor` class to accept `dataset_type` parameter - - Dataset-specific initialization in `Processor.__init__()` - - Dataset name displayed in task summary table - -3. **Template Registry** - Added dataset-specific prompt templates - - AIME template: includes `\boxed{}` wrapper for final answer - - GSM8K template: plain text answer without wrapper - - Templates applied based on `question["dataset_type"]` field - -4. **Answer Extraction Logic** - Fixed GSM8K answer extraction - - GSM8K has pre-extracted `"gold"` field with numeric answer - - `Gsm8kDataset.get_answer()` checks for `"gold"` field first - - Falls back to answer field if gold field not present - - `AimeDataset.get_answer()` simplified to remove duplicate method - -5. **Task ID Format** - Fixed duplicate prefix in task IDs - - Changed from `f"{dataset_type}_{eval_state.id}_{chunk_idx:03d}_{i:03d}"` - - To `f"{dataset_type}_{chunk_idx:03d}_{i:03d}"` - - Removed redundant `eval_state.id` (was "gsm8k" for GSM8K) - -6. **Column Width Adjustments** - Improved table formatting - - Task ID column: 25 characters - - Dataset column: 5 characters - - Prompt column: 40 characters - - Expected column: 10 characters - -**Testing Results:** -- ✅ GSM8K dataset loads correctly with 7473 questions -- ✅ Numeric answers extracted from full reasoning text -- ✅ Task summary table displays correctly with adjusted column widths -- ✅ Task IDs show correct format (e.g., `gsm8k_000_3169`) -- ✅ Both AIME and GSM8K datasets work with same script -- ✅ Answer extraction works for both boxed and plain text formats -- ✅ Progress tracking shows extracted answers for both datasets - -**Key Technical Decisions:** -- GSM8K uses `"question"` field instead of `"problem"` field -- GSM8K answer field contains full reasoning with `####` prefix -- Numeric answer extracted during dataset initialization -- Same regex grader pattern works for both datasets -- Dataset selection via CLI argument for separate runs -- Template registry supports different prompt formats per dataset -- Task ID format simplified to avoid duplication - -**Refactoring:** -- Removed duplicate `get_question()` method from `AimeDataset` -- Removed "2025" suffix from eval state ID (was remnant from old version) -- Removed "2025" suffix from task summary table output -- Removed "2025" suffix from progress tracking output -- Updated `Processor.__init__()` to initialize appropriate dataset based on type -- Updated `_process_single_case()` to handle both `"problem"` and `"question"` fields -- Updated `process()` method to display dataset name and use `dataset_type` for task states diff --git a/examples/llama-eval/llama-eval-new.py b/examples/llama-eval/llama-eval-new.py index 8426dae724..eacbe3d887 100755 --- a/examples/llama-eval/llama-eval-new.py +++ b/examples/llama-eval/llama-eval-new.py @@ -5,6 +5,7 @@ import json import os import re import subprocess +import sys import time from concurrent.futures import ThreadPoolExecutor, as_completed from dataclasses import dataclass, asdict @@ -34,6 +35,15 @@ Please reason step by step, and put your final answer within \\boxed{{}}.

-### Imports -- Standard library imports first (argparse, json, os, re, subprocess, sys, time) -- Third-party imports (requests, tqdm, datasets, flask) after standard library -- Relative imports not used -- Group imports by category with blank line between groups - -### Formatting -- 4-space indentation -- Max line length: 125 characters (per parent project's .flake8) -- Use double quotes for strings -- Use triple double quotes for docstrings -- Binary operators at the beginning of continued lines - -### Naming Conventions -- Classes: PascalCase (e.g., `AimeDataset`, `Grader`, `Processor`) -- Functions: snake_case (e.g., `normalize_number`, `get_prompt`) -- Variables: snake_case (e.g., `question_text`, `correct_count`) -- Constants: UPPER_SNAKE_CASE (e.g., `GRADER_PATTERNS`, `TEMPLATE_REGISTRY`) -- Private methods: prefix with underscore (e.g., `_load_dataset`, `_grade_regex`) - -### Types -- Use type hints for all function signatures -- Import from `typing` module: `Dict`, `List`, `Optional`, `Any`, `Tuple` -- Use `@dataclass` for data structures -- Prefer `Optional[T]` over `Union[T, None]` - -### Error Handling -- Use try/except for network requests and file operations -- Return `None` or `False` on errors when appropriate -- Use `ValueError` for invalid arguments -- Use `FileNotFoundError` for missing files -- CLI scripts should handle exceptions gracefully - -### Dataclasses -- Use `@dataclass` for structured data -- Define fields with explicit types -- Use `Optional[T]` for nullable fields -- Provide default values where appropriate - -### String Formatting -- Use f-strings for formatting (Python 3.6+) -- Use triple double quotes for multi-line strings -- Escape backslashes in regex patterns: `r'\\boxed{(\d+)}'` - -### File Paths -- Use `pathlib.Path` instead of string paths -- Create directories with `mkdir(parents=True, exist_ok=True)` -- Use `Path.home()` for user home directory - -### Logging -- Use `print()` for user-facing output -- Use `sys.stderr` for debug logging -- Simulator writes debug logs to `/tmp/simulator-debug.log` - -### Testing - -- Test script uses bash with `set -e` for strict error handling -- Simulator runs in background with PID tracking -- Tests verify correct answers, error cases, and edge cases -- Use `curl` for HTTP testing in shell scripts -
