c++ - nvcc fatal : Unsupported gpu architecture 'compute_20' while cuda9. 0 已安装

Question

我在安装 GROMACS-5.1.2 时遇到问题。该错误表明不支持 gpu 架构“compute_20”。我有 CUDA 9.0、g++4.9.3 和 GTX1080 GPU。我现在应该怎么做？有什么问题吗？

Answer 1

“compute_20”、“sm_20”和“sm_21”架构在 CUDA 8 和 9 中已弃用

分辨率

1. 更改为兼容的 CUDA 版本
2. 修改您的 CMake 文件以删除这些已弃用的架构
