| + | Par défaut, Tensorflow alloue l'ensemble de la mémoire GPU au programme, même s'il n'en nécessite que 10%. | ||
| + | Il existe une option permettant d'allouer seulement la mémoire GPU nécessaire. | ||
| + | Il faut ajouter les lignes suivantes: | ||
| + | <code> | ||
| + | config = tf.ConfigProto() | ||
| + | config.gpu_options.allow_growth = True | ||
| + | sess = tf.Session(config=config) | ||
| + | |||
