c++ - nvcc fatal : Unsupported gpu architecture 'compute_61' while CUDA 8. 0 已安装

Question

我在使用 luarocks 安装 cutorch 时遇到问题。该错误表明不支持 gpu 架构“compute_61”。经过一番搜索，我发现问题可能是由旧的 CUDA 版本引起的。但事实并非如此，因为我有 CUDA 8.0

可能是什么问题？

Answer 1

在安装 cutorch 开始时的 cmake 检查中，您有:

-- 找到 CUDA:/usr(找到合适的版本“7.5”，最低要求是“6.5”)

看起来您安装了两个 CUDA 版本 - 安装程序选择了 7.5。另一种选择是安装程序不支持 8.0。
