MegEngine

MegEngine est un framework de deep learning et un moteur de différenciation automatique utilisé pour entraîner et déployer des réseaux neuronaux. Il fonctionne comme une bibliothèque de programmation différentiable qui permet la création de modèles mathématiques où les opérations sont différentiables pour l'optimisation basée sur le gradient.

Le projet fournit un runtime de tenseur agnostique au matériel et un runtime de modèle multiplateforme, permettant aux modèles de s'exécuter sur diverses architectures matérielles CPU et GPU. Il utilise un moteur de graphe computationnel dynamique pour construire des graphes d'exécution à la volée, prenant en charge des formes d'entrée flexibles et un contrôle de flux complexe.

Le framework couvre tout le cycle de vie du modèle IA, de l'entraînement itératif du modèle et la validation au déploiement multiplateforme. Il intègre un pipeline de différenciation automatique pour calculer les gradients et fournit des outils pour exporter les modèles entraînés afin de les exécuter efficacement sur diverses plateformes matérielles.
