## Introduction

SlangPy is a cross-platform library designed to make calling GPU code written in Slang extremely simple and easy. It's core objectives are to:
- Make it quick and simple to call Slang functions on the GPU from Python
- Eradicate the boilerplate and bugs associated with writing compute kernels
- Grant easy access to Slang's auto-diff features
- Provide optional PyTorch support out of the box

## Documentation

See the [documentation][2] for more detailed information and examples.

More information about Slang in general can be found [here](https://shader-slang.com).

## Installation

SlangPy is available as pre-compiled wheels via PyPi. Installing SlangPy is as simple as running:

```bash
pip install slangpy
```

To enable PyTorch integration, simply ``pip install pytorch`` as usual and it will be detected automatically by SlangPy.

You can also compile SlangPy from source:

```bash
git clone https://github.com/shader-slang/slangpy.git --recursive
cd slangpy
pip install .
```
