macOS Development Setup

For macOS users, follow these steps to set up your development environment:

Install Tool for Python Environment and Dependency Management
There are multiple tools for managing Python environments and dependencies. Popular ones include pip and venv, Miniconda, and Anaconda. An alternative, uv, is described below.

Choose your favorite and make sure it is correctly installed.

Install Xcode Command Line Tools
Xcode provides essential compiler tools for macOS. Run the following command in your terminal to install it:
```
xcode-select --install
```

Create a Virtual Environment
It is highly recommended to create a virtual environment to isolate your project dependencies. The steps vary dependeing on the tool, one example is provided below for pip and venv:
```
python -m venv venv
source venv/bin/activate  # On macOS/Linux
venv\Scripts\activate     # On Windows
```
Install Dependencies
Install the required Python packages:

Mac requires an additional dependency, hnswlib, which should be installed with the package manager.

- Install the package in editable mode with development dependencies:

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

uv is a tool that simplifies Python dependency management. Follow these steps to set it up:

Install uv
Use pip to install uv:
```
pip install uv
```
Install the Required Python Version
Ensure the correct Python version is installed for your project:
```
uv python install
```
Sync Dependencies
Install all required dependencies, including extras, by running:
```
uv sync --all-extras
```
hnswlib Package Installation Error

If the hnswlib package fails to install with an error like fatal error: Python.h: No such file or directory, ensure you have installed Python development headers files and static libraries. On Ubuntu, this can be done via sudo apt-get install python3-dev.

💡 Tip: For more details, refer to the official uv installation guide.
