Distiller est une bibliothèque basée sur PyTorch créée par Intel avec des algorithmes pour réduire le poids des modèles Deep Learning. Les principaux exemples de réduction de poids du modèle sont la quantification, l'élagage, la distillation, etc., et Distiller est facile à utiliser. De plus, le tutoriel comprenait même une fonction qui vous permet de vérifier l'état de l'apprentissage en solidarité avec TensorBoard (merci).

Dans mon cas, lorsque j'ai essayé d'importer le Distiller ajouté à la bibliothèque, j'ai eu une erreur liée à la bibliothèque git, alors j'ai rétrogradé le mauvais gitdb2 et cela a été corrigé. (Ma version installée est 4.0.2)
$ pip uninstall gitdb2
$ pip install gitdb2==2.0.6

Pour le moment, je suis soulagé car il a bougé ε- (´∀ ` *) Hot Je l'ajouterai dès que je trouverai quelque chose.
