centos7的torch7安装cutorch时出错

Question

我想安装手电筒报错不知道怎么解决：

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

我已经安装了 cude 8.0 和 cudnn 。而且我还可以成功安装其他软件包，如 nnx、optim、inn。

我也遇到过。原因是由于torch lib中的一个新方法，见：https://github.com/torch/torch7/blob/master/lib/TH/THStorage.c#L69

通过在luarocks install cutorch 之前运行luarocks install torch 来更新Torch，您应该一切顺利。
