## 2. Install Python
You can install Python using uv:
```bash
uv python install 3.10
```
&nbsp;
> [!NOTE]
> I recommend installing a Python version that is at least 2 versions older than the most recent release to ensure PyTorch compatibility. For example, if the most recent version is Python 3.13, I recommend installing version 3.10 or 3.11. You can find out the most recent Python version by visiting [python.org](https://www.python.org/downloads/).

## 3. Install Python packages and dependencies
## 2. Install Python packages and dependencies
To install all required packages from a `pyproject.toml` file (such as the one located at the top level of this GitHub repository), run the following command, assuming the file is in the same directory as your terminal session:
```bash
uv add . --dev
uv sync --dev --python 3.11
```
> [!NOTE]
> If you do not have Python 3.11 available on your system, uv will download and install it for you.
>
> I recommend using a Python version that is at least 1-3 versions older than the most recent release to ensure PyTorch compatibility. For example, if the most recent version is Python 3.13, I recommend using version 3.10, 3.11, 3.12. You can find out the most recent Python version by visiting [python.org](https://www.python.org/downloads/).
> [!NOTE]
> If you have problems with the following commands above due to certain dependencies (for example, if you are using Windows), you can always fall back to regular pip:
> `uv add pip`
> `uv run python -m pip install -U -r requirements.txt`

Note that the `uv add` command above will create a separate virtual environment via the `.venv` subfolder. (In case you want to delete your virtual environment to start from scratch, you can simply delete the `.venv` folder.)
Note that the `uv sync` command above will create a separate virtual environment via the `.venv` subfolder. (In case you want to delete your virtual environment to start from scratch, you can simply delete the `.venv` folder.)
You can install new packages, that are not specified in the `pyproject.toml` via `uv add`, for example:
