ComfyUI est un outil puissant pour la génération d’images par IA, qui offre flexibilité et contrôle sur les flux de travail. Dans cet article, nous vous guiderons tout au long du processus d’installation de ComfyUI sur une machine Windows, y compris la configuration requise, les étapes d’installation et des conseils de dépannage.
Table des matières
Configuration requise
Avant de commencer le processus d’installation, assurez-vous que votre système répond aux prérequis matériels et logiciels suivants :
Configuration matérielle requise
- Processeur: Processeur multicœur moderne (Intel i5/i7 ou AMD Ryzen recommandé).
- GPU: GPU NVIDIA compatible CUDA (minimum 6GB VRAM, bien que 8GB+ VRAM soit idéal pour de meilleures performances). Par exemple :
- NVIDIA GTX 1660 ou supérieur
- GPU NVIDIA RTX 3060/3070/3080/séries 40 et 50
- GPU NVIDIA des séries A et Tesla
Configuration logicielle requise
- Système d’exploitation: Windows 10 ou Windows 11 (64 bits).
- Version de Python: Python 3.10 ou version ultérieure.
- Pilotes NVIDIA: Assurez-vous que les pilotes les plus récents sont installés pour la compatibilité CUDA.
- Disponible sur Téléchargements de pilotes NVIDIA.
- Installer NVIDIA CUDA :
- Git: Git doit être installé pour cloner le dépôt.
- Disponible sur Git for Windows.
Guide étape par étape pour installer ComfyUI sous Windows

Étape 2 : Installer Git
- Téléchargez Git depuis Git for Windows.
- Suivez les instructions d’installation et assurez-vous que Git est ajouté au PATH de votre système.
Étape 3 : Lancer l’installation de la version bureau
- Double-cliquez sur la version téléchargée pour lancer l’installation de ComfyUI.
Sélectionnez la version GPU
Choisissez l’emplacement d’installation :
Prise en main avec un modèle
Module manquant :
Qui peut être téléchargé directement en cliquant sur télécharger.
Étape 4 : Lancer ComfyUI
Étape 5 : Essayer le prompt et le modèle par défaut pour générer une image
Lorsque vous cliquez sur Exécuter, une erreur s’affiche.
Erreur complète ci-dessous :
Rapport d’erreur ComfyUI
Détails de l’erreur
- ID de nœud : 7
- Type de nœud : CLIPTextEncode
- Type d’exception : RuntimeError
- Message d’exception : CUDA error: operation not supported
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1
Compile withTORCH_USE_CUDA_DSAto enable device-side assertions.

Après investigation, j’ai découvert que le problème avait été mentionné sur GitHub :
L’exécutable ComfyUI Desktop (Windows) n’accepte pas les paramètres sur sa ligne de commande · Issue #7087 · comfyanonymous/ComfyUI
Mesure d’atténuation :
La mesure d’atténuation consiste à définir « Use CUDA malloc for memory allocation » sur désactivé .
Étape 6 : Générer l’image
Après avoir résolu le problème et cliqué à nouveau sur Exécuter, j’ai enfin pu générer l’image.
Vérification de l’installation
Pour vous assurer que ComfyUI est correctement installé et fonctionne :
- Testez les flux de travail de base en générant des images d’exemple.
- Vérifiez l’utilisation du GPU avec des outils comme Gestionnaire des tâches ou NVIDIA-SMI pour confirmer que l’accélération GPU est active.
Résolution des problèmes courants
Problème 1 : Python non reconnu
- Assurez-vous que Python est ajouté à votre PATH pendant l’installation.
- Sinon, ajoutez manuellement le répertoire Python à votre PATH via les Variables d’environnement.
Problème 2 : Erreurs de compatibilité CUDA
- Vérifiez que vos pilotes NVIDIA et votre boîte à outils CUDA sont à jour.
- Vérifiez la compatibilité de votre GPU avec la version de CUDA installée.
Conclusion
En suivant ce guide, vous devriez maintenant avoir installé ComfyUI avec succès et l’avoir en cours d’exécution sur votre machine Windows. Grâce à son interface intuitive et à ses fonctionnalités puissantes, vous êtes prêt à explorer les flux de travail de génération d’images par IA.
