Salut, j'essayais de former un modèle quand je reçois ce message d'erreur: Si je comprends bien, il dit que je suis hors de la VRAM mais j'ai un Asus GTX1080 A8G Gaming qui devrait avoir assez de Vram . Je l'ai essayé avant que tout fonctionne, mais soudainement, ça ne marchera plus. Mon profond net:OOM de la carte graphique CUDA/Tensorflow

à ce sujet: « Je l'ai essayé avant tout fonctionnait mais soudainement de nulle part, il ne marchera pas plus. » Peut-être que votre GPU a des processus zombies qui maintiennent la mémoire allouée. Vous pouvez généralement observer ceci avec 'nvidia-smi'. Une solution possible dans ce cas serait de redémarrer. –
