### Prerequisites

- GraalVM
- [Python support](https://www.graalvm.org/latest/reference-manual/python/)
- [GraalVM](https://www.graalvm.org/)
- [GraalPy](https://www.graalvm.org/latest/reference-manual/python/)

>Note: As of GraalVM for JDK 21, the Python runtime (GraalPy) is available as a standalone distribution.
## Preparation

1. Download and install the latest GraalVM JDK with the Python support using the [GraalVM JDK Downloader](https://github.com/graalvm/graalvm-jdk-downloader).
1. Download and install the latest GraalVM JDK using [SDKMAN!](https://sdkman.io/).
```bash
sdk install java 21.0.1-graal
```
2. Download and install GraalPy using `pyenv`:
```bash
pyenv install graalpy-23.1.0
```
Alternatively, download a compressed GraalPy installation file appropriate for your platform from [GitHub releases](https://github.com/oracle/graalpython/releases).

3. Set the `GRAALPY_HOME` environment variable:
```bash
bash <(curl -sL https://get.graalvm.org/jdk) -c 'python'
export GRAALPY_HOME=/.pyenv/versions/graalpy-23.1.0
```

2. Download or clone GraalVM demos repository and navigate into the `graalpy-notebook-example` directory:
```bash
git clone https://github.com/graalvm/graalvm-demos
