**Texor** is a lightweight, native deep learning framework built from scratch in Python. It provides a PyTorch-style API without the overhead of large ML frameworks like TensorFlow or PyTorch.

## 🚀 Key Features

- **🎯 Native Implementation**: 100% Python/NumPy/Numba - no TensorFlow or PyTorch dependencies
- **⚡ Lightweight**: ~260MB total size vs ~4GB for TensorFlow + PyTorch
- **🧠 Complete ML Stack**: Automatic differentiation, neural networks, optimizers
- **🔧 PyTorch-style API**: Familiar interface for ML practitioners
- **⚡ JIT Compilation**: Numba-optimized operations for performance
- **🖥️ GPU Ready**: Optional CUDA support via CuPy
- **📦 Easy Installation**: Simple pip install with minimal dependencies

## 🏗️ Architecture

```

├── core/           # Tensor operations, autograd, backend
├── nn/             # Neural network layers and models
├── optim/          # Optimizers (SGD, Adam, RMSprop)
├── data/           # Dataset utilities and data loaders
└── cli/            # Command-line interface
```

## 📦 Installation

```bash
# Basic installation
pip install numpy numba

# For GPU support (optional)
pip install cupy

# Install Texor
git clone https://github.com/letho1608/texor
cd texor
pip install -e .
```

## 🔥 Quick Start

### Basic Tensor Operations
```python
import texor
from texor.core import Tensor, randn

# Create tensors
x = randn((3, 4))
y = randn((4, 2))

# Matrix operations with autograd
z = x @ y
z.backward()
print(x.grad)  # Gradients computed automatically
```

### Neural Networks
```python
from texor.nn import Sequential, Linear, ReLU
from texor.nn.loss import MSELoss
from texor.optim import Adam

# Define model
model = Sequential([
    Linear(784, 128),
    ReLU(),
    Linear(128, 64), 
    ReLU(),
    Linear(64, 10)
])

# Setup training
optimizer = Adam(model.parameters(), lr=0.001)
criterion = MSELoss()

# Training loop
for epoch in range(epochs):
    # Forward pass
    predictions = model(x_train)
    loss = criterion(predictions, y_train)
    
    # Backward pass
    loss.backward()
    optimizer.step()
    optimizer.zero_grad()
```

### High-level API
```python
# Keras-style high-level API
model.compile(optimizer='adam', loss='mse')
model.fit(x_train, y_train, epochs=10, batch_size=32)
```

## 🧪 Complete Example

```python
from texor.core import randn
from texor.nn import Sequential, Linear, ReLU
from texor.nn.loss import CrossEntropyLoss
from texor.optim import Adam

# Generate sample data
x_train = randn((1000, 20))
y_train = randn((1000, 10))

# Create model
model = Sequential([
    Linear(20, 50),
    ReLU(),
    Linear(50, 10)
])

# Setup training
optimizer = Adam(model.parameters())
criterion = CrossEntropyLoss()

# Train
for epoch in range(50):
    pred = model(x_train)
    loss = criterion(pred, y_train)
    
    loss.backward()
    optimizer.step()
    optimizer.zero_grad()
    
    if epoch % 10 == 0:
        print(f'Epoch {epoch}, Loss: {loss.data.item():.4f}')
```
