Installations for In-Process Functions

This document outlines the requirements and installation steps necessary to enable in-process functions (e.g., Text to Array, Hex to Int).

The following requirements must be configured on each server.

Python Requirements

Minimal Python Version: 3.11.7 and above.

Verify that the python3 executable points to the correct version:
```
python3 --version
```
If python3 does not point to a version that meets the minimal requirements, update the Python version alternatives.
- Check the current configuration:
```
sudo update-alternatives --config python3
```
- Change the version (replace X with your installed sub-version):
```
sudo update-alternatives --set python3 /usr/bin/python3.X
```

Warning

Restart Required: If the default Python version was changed, you must restart Sqream workers for the update to take effect.

Install CUDA Toolkit

Installation steps may vary based on the operating system version and architecture. Please refer to the official NVIDIA documentation for specific packages.

Install CuPy Library

In-process functions are Python-based and utilize the CuPy library. As these functions depend on the local Python installation, this library must be installed manually.
