QGIS/Installation plugin map segmenter: erreur DLL
Bonjour,
J'essaie d'installr le plugin map segmenter :
https://github.com/sirebellum/qgis-segmentation
Mais dans le gestionnaire de plugin lorsque je coche le plugin j'ai un message d'erreur.
Impossible de charger l'extension 'segmenter' provoque une erreur lors de l'appel à sa méthode classFactory()
Code:
ImportError: DLL load failed while importing lib: La procédure spécifiée est introuvable.

Re: QGIS/Installation plugin map segmenter: erreur DLL
Bonjour,
L’erreur ne vient pas directement du plugin Map Segmenter, mais d’une dépendance Python : en activant le plugin, scikit-learn se charge (from sklearn.cluster import KMeans) et tente d’importer pyarrow, qui échoue dans l’environnement Python embarqué de QGIS (Windows) avec un “DLL load failed while importing lib”. C’est un souci connu avec QGIS 3.34. + pyarrow sous Windows.
Voici 3 pistes qui résolvent généralement le problème :
- Purger les “user site-packages” hors de QGIS (solution la plus propre)
QGIS charge chez toi C:\Users\lcelati\AppData\Roaming\Python\Python312\site-packages\… (on le voit dans la trace).
Ferme QGIS puis renomme temporairement ce dossier (ex. site-packages_OFF) pour empêcher QGIS d’y piocher, ou crée un nouveau profil QGIS (“Profil utilisateur”) afin de repartir sans paquets externes.
Rouvre QGIS et réactive le plugin.
- Installer pyarrow (et scikit-learn) dans le Python de QGIS (peut marcher selon les machines)
Ouvre OSGeo4W Shell (QGIS LTR).
Exécute :
py3_env
python -m pip install --upgrade pip
python -m pip install --upgrade scikit-learn
python -m pip install --upgrade pyarrow
Relance QGIS et active le plugin.
- Tester avec une version de QGIS plus récente
Plusieurs retours indiquent moins de problèmes de dépendances (Arrow/pyarrow) avec des versions ultérieures de QGIS (3.36/3.38). Si possible, essaie sur une installation parallèle “Standalone” récente.
À défaut, des alternatives de segmentation fonctionnent sans cet enchaînement de dépendances (ex. Deepness, Geo-SAM), si tu dois avancer tout de suite.
N’hésite pas à me dire ce que tu constates après l’option 1 (renommage du dossier site-packages / nouveau profil) : c’est généralement la plus rapide pour éliminer le conflit.
