Cette section n’a pas la prétention de traiter tous les cas possibles d'installation de Python …
Le principe est d'avoir la bonne version et ses dépendances pour le module SQWarePredict.

Avant de vous lancer dans l’installation, vous devez d'abord avoir la version de dbSQWare avec SQWarePredict (v2025.01 mini) pour avoir les dépendances.

Principe

Nous allons :

• Installer Python-3.12.8
• Configurer l'environnement
• Installer les dépendances

Installation

Mise à jour de l'environnement

Dans le ~dbsqware/.bash_profile

# env Python 3.12.8 (pour SQWarePredict)

export LD_LIBRARY_PATH=/home/dbsqware/dbSQWare/SQWarePredict/python/3.12.8/lib:$LD_LIBRARY_PATH

# vérification du PATH
