我想配置config.mk文件以使用cuda。我修改了以下选项：
USE_CUDA = 1
ADD_LDFLAGS = /usr/local/cuda-8.0/lib64
ADD_CFLAGS = /usr/local/cuda-8.0/lib64
USE_CUDA_PATH = /usr/local/cuda
USE_CUDNN = 1
USE_NVRTC = 1
运行时make -j8出现以下错误：
cd /home/wanger/MXNet/mxnet/dmlc-core; make libdmlc.a USE_SSE=1 config=/home/wanger/MXNet/mxnet/config.mk; cd /home/wanger/MXNet/mxnet

这表明您的问题在于目录的权限配置不正确/usr/local/cuda。您似乎试图执行它，就好像它是一个命令文件一样。您最想要的是执行/usr/local/cuda/bin/nvcc。
编辑您的 makefile 以便 CUDA 命令读取/usr/local/cuda/bin/nvcc（注意“cuda”和“bin”之间没有空格）并重试。
