# Installation

You can install TRL either from PyPI or from source:

## PyPI

Install the library with pip or [uv](https://docs.astral.sh/uv/):

uv is a fast Rust-based Python package and project manager. Refer to [Installation](https://docs.astral.sh/uv/getting-started/installation/) for installation instructions.

```bash
uv pip install trl
```

```bash
pip install trl
```

## Source

You can also install the latest version from source. First clone the repo and then run the installation with `pip`:

```bash
git clone https://github.com/huggingface/trl.git
cd trl/
pip install -e .
```

If you want the development install you can replace the pip install with the following:

```bash
pip install -e ".[dev]"
```
