Une erreur lors de l'installation cutorch dans Torch7 de centos7

Question

Je veux installer le cutorch et obtenir une erreur et je ne sais pas comment le résoudre:

(tf0.12.1) [root@sd-bigdata-gpu-02 deepmask]# luarocks install cutorch

j'installer la Cude 8.0 et cudnn. Et je pourrais aussi installer d'autres paquets comme nnx, optim, inn avec succès.

J'ai également rencontré cela. La cause est due à une nouvelle méthode dans la torche lib, voir: https://github.com/torch/torch7/blob/master/lib/TH/THStorage.c#L69

mise à jour en exécutant la flamme luarocks install torch avant luarocks install cutorch et vous devriez être bon d'aller.
