在没有Anaconda Python 3.6的Ubuntu 18.04 GPU TitanX CUDA 9.1 CuDNN 7.1上安装Caffe时出现问题。运行make -j8 all会出现以下错误：

我尝试在Makefile.Config中为CuDNN提供目录地址（标头为/ usr / lib / x86_64-linux-gnu /和usr / local / include）。这是Makefile.Config的内容：

我还尝试在libcudnn.so.7.1.2和libcudnn.so之间创建符号链接：
ln -sf /usr/local/cuda/lib64/libcudnn.so.7.1.2 /usr/local/cuda/lib64/libcudnn.so.7
键入ld -lcudnn --verbose会出现以下最后几行：

我检查了cudnn在（sudo find / -name libcudnn*so*）的位置，并得到以下回答：
/home/meriemlio/Downloads/cuda/targets/ppc64le-linux/lib/libcudnn.so
/root/caffe/libcudnn.so
查找：“ / run / user / 1000 / gvfs”：权限被拒绝
查找：“ / run / user / 120 / gvfs”：权限被拒绝
/usr/lib/x86_64-linux-gnu/libcudnn.so
我尝试添加目录ld并没有通过键入例如来检查libcudnn：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu/
我仍然遇到相同的错误。 有人对如何解决这个问题有任何线索吗？
