# Phase 4: Complete Pipeline Implementation

## 🎯 Overview
Complete TestTime RLVR pipeline implementation based on AZR (Absolute Zero Reasoner) methodology. The pipeline successfully integrates LLM solution generation, IPO triple extraction, three-task reasoning (induction/deduction/abduction), and execution-based evaluation.

## 📋 Implementation Details

### 1. Complete Pipeline Architecture
- **File**: `test_complete_pipeline.py`
- **Main Class**: `CompleteTestTimePipeline` in `complete_pipeline.py`
- **Flow**: LLM Solution → IPO Extraction → Task Generation → LLM Evaluation → Reward Computation

### 2. Key Components

#### 2.1 Pipeline Execution (`test_complete_pipeline.py`)
```python
def main():
    # Model loading with VLLM optimization
    model, tokenizer = InitialSolutionGenerator.load_model_with_optimizations(
        args.model, device, config, use_vllm=True
    )
    
    # Pipeline initialization
    pipeline = CompleteTestTimePipeline(model, tokenizer, config, logger)
    
    # Complete pipeline execution
    result = pipeline.run_complete_pipeline(benchmark_config, problem_id)
```

#### 2.2 IPO Triple Extraction (Fixed)
- **Issue**: Previously failed due to assert parsing regex issues
- **Solution**: Switched to structured data extraction from `base_input`/`plus_input`
- **Key Change**: Use LLM-generated solution execution for output computation
```python
def _extract_test_cases(self, problem: Dict[str, Any], solution: str) -> List[Tuple[str, str]]:
    # Use structured benchmark data instead of assert parsing
    actual_output = self._execute_llm_solution(solution, func_name, inp_args)
```

#### 2.3 Three Reasoning Tasks
- **Induction**: Deduce function from input/output pairs + message
- **Deduction**: Predict output from code + input  
- **Abduction**: Predict input from code + output

#### 2.4 Evaluation System (AZR-based)
- **Execution-based comparison** instead of string matching
- **Function name normalization** to `f` for consistency
- **Program execution** using AZR's PythonExecutor

### 3. Critical Bug Fixes

#### 3.1 IPO Extraction Failure (Solved)
**Problem**: 0 triples extracted due to regex parsing failure
```
assert remove_lowercase("PYTHon")==('PYTH')  # Failed to parse parentheses
```
**Solution**: Use structured `base_input`/`plus_input` data directly

#### 3.2 Function Name Normalization Bug (Solved)
**Problem**: Function definitions normalized to `f` but calls weren't
**Solution**: Normalize both definitions and calls consistently

#### 3.3 Answer Extraction Pattern Mismatch (Solved)
**Problem**: Induction tasks expected `<answer>` tags but code looked for ````python``` blocks
**Solution**: Updated extraction pattern to use `<answer>` tags consistently

### 4. Prompt System Integration

#### 4.1 AZR Template Usage
- **File**: `absolute_zero_reasoner/data_construction/prompts.py`
- **Key Templates**: 
  - `code_function_predictor_prompt` (induction)
  - `code_input_predictor_prompt` (abduction)
  - `code_output_predictor_prompt` (deduction)

#### 4.2 Docstring Extraction and Usage
- Extract docstrings from LLM-generated solutions
- Use as `message` parameter in induction tasks
- Improves task quality and LLM understanding

### 5. Benchmark Integration

#### 5.1 Supported Benchmarks
- **MBPP+**: `/home/ubuntu/RLVR/TestTime-RLVR-v2/evaluation/code_eval/data/MbppPlus.jsonl`
- **HumanEval+**: `/home/ubuntu/RLVR/TestTime-RLVR-v2/evaluation/code_eval/data/HumanEvalPlus.jsonl`
- **Test mode**: Simple example problems

#### 5.2 Problem Loading
```python
# Real benchmark usage
benchmark_config = BenchmarkConfig.get_mbpp_config()
problem = pipeline.benchmark_loader.load_problem(benchmark_config, "Mbpp/478")
```

### 6. Model Integration

#### 6.1 VLLM Optimization
- **Faster inference** with VLLM backend
- **Temperature control**: 0.05 for reasoning tasks
- **GPU memory management** with cleanup

#### 6.2 Model Configuration
```python
config = TestTimeConfig(
    model_name="Qwen/Qwen2.5-7B",
    max_adaptation_steps=3,
    task_distribution={'induction': 0.4, 'deduction': 0.3, 'abduction': 0.3},
    max_tasks_per_type=3
)
```

### 7. Result Output System

#### 7.1 Detailed File Structure
```
/tmp/{benchmark}/{problem_id}/
├── initial_solution/          # LLM's original solution
├── ipo_triples/              # Input-Program-Output triples  
├── task_prompts/             # Generated reasoning tasks
├── llm_responses/            # LLM responses to tasks
├── extracted_answers/        # Extracted answers from responses
├── {problem_id}_reward_analysis.json
├── {problem_id}_reward_summary.txt
└── {problem_id}_pipeline_summary.json
```

#### 7.2 Evaluation Metrics
- **Accuracy**: Execution-based comparison (0.0 or 1.0)
- **Task-type distribution**: Separate metrics for induction/deduction/abduction
- **Overall pipeline success**: All steps completed successfully

### 8. Execution Example

#### 8.1 Command Line Usage
```bash
#!/bin/bash
export CUDA_VISIBLE_DEVICES=6

python test_complete_pipeline.py \
    --model "Qwen/Qwen2.5-7B" \
    --benchmark "mbpp" \
