Simple installation (recommended)

You will need Python 3.12 or higher. If you run a 32-bits Windows system, you will also need a C compiler. Set up a virtual environment; instructions will vary according to you installation.

Python’s built-in venv module is the recommended way to create a virtual environment.

python -m venv venv

Activate the environment:

On macOS/Linux:
```
source venv/bin/activate
```
On Windows:
```
venv\Scripts\activate
```

If you prefer virtualenv, install it first:

pip install virtualenv
virtualenv venv

Activate the environment:

On macOS/Linux:
```
source venv/bin/activate
```
On Windows:
```
venv\Scripts\activate
```

If you manage environments with Conda:

conda create --name lightwin python=3.x
conda activate lightwin

Once it is activated, run the following command:

pip install lightwin[cython]

Note that Cython is not mandatory, but speeds up calculations. If you run into a Cython related issue, you can always:

pip install lightwin
