NVCC problem

[jxgu1016]

when compiling Cython with cuda 8.0(cudnn included), I met this problem. Can anyone help me solve this? My python version is 2.7 and maybe that's the source of my pro...

这个问题主要在于你没装nvidia-drive, cuda或者你没将其加入到.bashrc下：可以参考nvidia cuda
主要在你的.bashrc文件下加入：
export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
