![pytorch-dml Banner](banner.png)

[![PyPI version](https://badge.fury.io/py/pytorch-dml.svg)](https://badge.fury.io/py/pytorch-dml)
[![PyPI](https://img.shields.io/pypi/v/pytorch-dml)](https://pypi.org/project/pytorch-dml/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
[![Tests](https://img.shields.io/badge/tests-passing-brightgreen)](tests/)

**pytorch-dml** is a production-ready library for collaborative neural network training, incorporating Deep Mutual Learning (DML) and related research advances.

> 🎉 **Now on PyPI!** Install with `pip install pytorch-dml` - Production-ready with 13/13 tests passing

## 🚀 Quick Start

### Installation

```bash
pip install pytorch-dml
```

### 5-Line Example

```python
from pydml import DMLTrainer
from torchvision import models

models = [models.resnet18(), models.resnet18()]
trainer = DMLTrainer(models, device='cuda')
trainer.fit(train_loader, val_loader, epochs=100)
```

### Complete Example

```python
import torch
from dml-py import DMLTrainer, DMLConfig
from dml-py.models.cifar import resnet32
from dml-py.utils.data import get_cifar100_loaders

# Load data
train_loader, val_loader, test_loader = get_cifar100_loaders(
    batch_size=128, download=True
)

# Create models
models = [resnet32(num_classes=100) for _ in range(2)]

# Configure DML
config = DMLConfig(
    temperature=3.0,
    supervised_weight=1.0,
    mimicry_weight=1.0
)

# Setup optimizers
optimizers = [
    torch.optim.SGD(m.parameters(), lr=0.1, momentum=0.9, weight_decay=5e-4)
    for m in models
]

# Train collaboratively
trainer = DMLTrainer(models, config=config, device='cuda', optimizers=optimizers)
history = trainer.fit(train_loader, val_loader, epochs=200)

# Evaluate
test_metrics = trainer.evaluate(test_loader)
print(f"Test Accuracy: {test_metrics['val_acc']:.2f}%")
```
