MegEngine
MegEngine este un framework de deep learning și un motor de diferențiere automată utilizat pentru antrenarea și deployarea rețelelor neuronale. Funcționează ca o bibliotecă de programare diferențiabilă care permite crearea de modele matematice în care operațiunile sunt diferențiabile pentru optimizarea bazată pe gradient.
Proiectul oferă un runtime de tensori hardware-agnostic și un runtime de model cross-platform, permițând modelelor să se execute pe diverse arhitecturi hardware CPU și GPU. Utilizează un motor de graf computational dinamic pentru a construi grafuri de execuție din mers, suportând forme de input flexibile și control flow complex.
Framework-ul acoperă întregul ciclu de viață al modelului AI, de la antrenarea și validarea iterativă a modelului până la deployment-ul cross-platform. Integrează un pipeline de diferențiere automată pentru a calcula gradienții și oferă instrumente pentru exportarea modelelor antrenate pentru a rula eficient pe diverse platforme hardware.
