**Transform messy datasets into ML-ready gold.** A powerful, configurable pipeline for dataset processing, quality assessment, and standardization—built by ML practitioner(s), for ML practitioners.

---

## 🎯 Why DatasetPipeline?

**The Problem:** You're drowning in data preprocessing chaos. Multiple formats, inconsistent schemas, duplicate records, quality issues—and you're spending more time wrangling data than training models.

**The Solution:** DatasetPipeline automates the entire journey from raw data to model-ready datasets with reproducible, configurable workflows.

### Born from Real-World Pain 🔥

This project emerged from my experience as a data engineer and MLOps practitioner. I was constantly:

- Ingesting diverse datasets for LLM fine-tuning
- Converting everything to OpenAI-compatible formats
- Writing repetitive preprocessing scripts
- Juggling deduplication, quality checks, and format conversions
- Maintaining brittle pipelines across multiple projects

What started as manageable became overwhelming. DatasetPipeline was built to solve these exact pain points—turning hours of manual work into minutes of configuration.

---

## ✨ Features

| Feature | Description |
|---------|-------------|
| 🔌 **Multi-Source Loading** | Hugging Face datasets, local files, cloud storage |
| 🔄 **Format Flexibility** | SFT, DPO, conversational, text—convert between any format |
| 🧹 **Smart Deduplication** | Semantic similarity using embeddings, not just exact matches |
| 📊 **Quality Analysis** | Automated categorization and quality scoring |
| ⚙️ **YAML Configuration** | Reproducible workflows, version-controlled pipelines |
| 🖥️ **CLI Interface** | Simple commands, powerful automation |
| 🚀 **GPU Acceleration** | Optional GPU support for heavy processing |

---

## 🚀 Quick Start

### Installation

```bash
# Recommended: Use as isolated tool
uv tool install datasetpipeline

# Or with pip
pip install datasetpipeline

# For full features (embeddings, GPU support)
pip install "datasetpipeline[all]"
```

### Your First Pipeline

```bash
# Generate a minimal sample configuration with comments
datasetpipeline sample my-first-job.yml --template minimal

# Or generate a full sample with all options and comments
datasetpipeline sample my-first-job.yml --template full

# Run the pipeline
datasetpipeline run my-first-job.yml

# That's it! 🎉
```

---

## ⚙️ Configuration Guidelines

### 🚨 Important Configuration Rule

**When disabling pipeline components, you must keep the section keys present with `null` values. Never completely remove the top-level keys.**

#### ✅ Correct Way to Disable Components

```yaml
load:
  huggingface:
    path: "teknium/OpenHermes-2.5"
    split: "train"

format:
  sft:
    use_openai: true

# Disable deduplication - keep the key with null
deduplicate: null

# Disable analysis - keep the key with null  
analyze: null

save:
  local:
    directory: "output"
    filetype: "jsonl"
```

#### ❌ Wrong Way (Will Cause Errors)

```yaml
load:
  huggingface:
    path: "teknium/OpenHermes-2.5"
    split: "train"

format:
  sft:
    use_openai: true

# DON'T DO THIS - completely removing keys
# deduplicate: <-- missing entirely
# analyze: <-- missing entirely

save:
  local:
    directory: "output"
    filetype: "jsonl"
```

#### 💡 Alternative: Comment Out Values, Keep Keys

```yaml
load:
  huggingface:
    path: "teknium/OpenHermes-2.5"
    split: "train"

format:
  sft:
    use_openai: true

# Temporarily disable deduplication
deduplicate:
  # semantic:
  #   threshold: 0.85
  #   column: "messages"

# Disable analysis for now
analyze:
  # quality:
  #   column_name: "messages"
  #   categories: ["code", "reasoning"]

save:
  local:
    directory: "output"
    filetype: "jsonl"
```

### Why This Matters

DatasetPipeline expects all major pipeline sections (`load`, `format`, `deduplicate`, `analyze`, `save`) to be present in the configuration. This design ensures:

- **Consistent pipeline structure** across all jobs
- **Clear intent** - you explicitly choose to skip steps vs. forgetting them
- **Easy re-enablement** - uncomment values instead of rewriting sections
- **Better error messages** - the pipeline knows what you intended

### 🎛️ Managing Configuration Complexity

**Problem**: The full sample configuration can be overwhelming with all comments and options.

**Solutions**:

1. **Start minimal** - Use `--template minimal` as a starting point for clean, simple configs
2. **Use templates** - Pre-built configurations for common use cases (`--template sft`, `--template dpo`, `--template analysis`)
3. **Progressive enhancement** - Start simple, add complexity as needed
4. **Reference mode** - Use `--template full` when you need to see all available options

## 📖 Real-World Example

Transform a Hugging Face dataset into training-ready format:

```yaml
# jobs/sft-training.yml
load:
  huggingface:
    path: "teknium/OpenHermes-2.5"
    split: "train"
    take_rows: 10000

format:
  sft:
    use_openai: true
    column_role_map:
      system: "system"
      human: "user" 
      gpt: "assistant"

deduplicate:
  semantic:
    threshold: 0.85
    column: "messages"

analyze:
  quality:
    column_name: "messages"
    categories: ["code", "reasoning", "creative", "factual"]

save:
  local:
    directory: "training_data"
    filetype: "jsonl"
```

```bash
datasetpipeline run jobs/sft-training.yml
```

**Result:** Clean, deduplicated, standardized training data ready for your LLM fine-tuning pipeline.

## 🎨 Advanced Configuration

### Conditional Processing

```yaml
load:
  huggingface:
    path: "my-dataset"
    filters:
      quality_score: ">= 0.8"
      language: "en"

format:
  sft:
    use_openai: true
    min_message_length: 10
    max_conversation_turns: 20

# Skip deduplication for this job
deduplicate: null

analyze:
  quality:
    column_name: "text"
    min_score: 0.7
    categories: ["technical", "creative"]
    save_analysis: true

save:
  local:
    directory: "filtered_data"
    filetype: "parquet"
```

### Quality-Based Filtering

```yaml
load:
  local:
    path: "raw_data.jsonl"

# Skip formatting - data is already in correct format
format: null

deduplicate:
  exact:
    column: "content"

analyze:
  quality:
    column_name: "text"
    min_score: 0.7
    categories: ["technical", "creative"]
    save_analysis: true

save:
  local:
    directory: "cleaned_data"
    filetype: "jsonl"
```

### Custom Deduplication

```yaml
load:
  huggingface:
    path: "my-dataset"

format:
  text:
    column: "content"

deduplicate:
  semantic:
    threshold: 0.9
    model: "sentence-transformers/all-MiniLM-L6-v2"
    batch_size: 32
    use_gpu: true

# Skip analysis for faster processing
analyze: null

save:
  local:
    directory: "deduped_data"
    filetype: "parquet"
```

## 🏗️ Extensible Architecture

DatasetPipeline is built with extensibility at its core. Each major component uses **Abstract Base Classes (ABC)**, making it incredibly easy to add new functionality:

```python
# Want a new data loader? Just extend BaseLoader
class MyCustomLoader(BaseLoader):
    def load(self) -> Dataset:
        # Your custom loading logic
        pass

# Need a specialized formatter? Extend BaseFormatter  
class MyFormatter(BaseFormatter):
    def format(self, dataset: Dataset) -> Dataset:
        # Your formatting logic
        pass
```

### 🔌 Pluggable Components

| Component | ABC Base Class | Easy to Add |
|-----------|----------------|-------------|
| 📥 **Loaders** | `BaseLoader` | New data sources (APIs, databases, cloud storage) |
| 🔄 **Formatters** | `BaseFormatter` | Custom data transformations and schemas |
| 🧹 **Deduplicators** | `BaseDeduplicator` | Novel similarity algorithms |
| 📊 **Analyzers** | `BaseAnalyzer` | Domain-specific quality metrics |
| 💾 **Savers** | `BaseSaver` | New output formats and destinations |

### 🚀 Contribution-Friendly

This architecture means:

- **Low barrier to entry**: Add one component without touching others
- **Clean interfaces**: Well-defined contracts between components
- **Easy testing**: Mock and test components in isolation
- **Community growth**: Contributors can focus on their expertise area

**Example**: Want to add PostgreSQL loading? Just implement `BaseLoader` and you're done!

## 🏃‍♂️ Performance Tips

- **GPU Acceleration**: Install with `[gpu]` extras for faster embeddings
- **Batch Processing**: Use larger batch sizes for better throughput
- **Memory Management**: Process large datasets in chunks
- **Caching**: Embeddings are cached automatically

```bash
# High-performance setup
pip install "datasetpipeline[gpu]"
export PYTORCH_CUDA_ALLOC_CONF=max_split_size_mb:512
```
