NVCC src/caffe/util/math_functions.cu

解决办法:由于安装的cuda版本是7.5，当前下载的caffe版本比较新，需要修改里面的makefile文件，屏蔽下面的代码，cuda<8.0

 

 

In the Makefile.example, try commenting out the *_60 and *_61 lines (for compatibility with CUDA < 8.0).

CUDA_ARCH := -gencode arch=compute_20,code=sm_20 \
        -gencode arch=compute_20,code=sm_21 \
        -gencode arch=compute_30,code=sm_30 \
        -gencode arch=compute_35,code=sm_35 \
        -gencode arch=compute_50,code=sm_50 \
        -gencode arch=compute_52,code=sm_52 \
        #-gencode arch=compute_60,code=sm_60 \
        #-gencode arch=compute_61,code=sm_61 \
        #-gencode arch=compute_61,code=compute_61
