error while loading shared libraries: libcudart.so.8.0: cannot open shared object file: No such file or directory

首先确认/etc/profile中的路径包含了cuda8.0的安装路径及相应的库文件

sudo vim /etc/profile

添加以下路径

export PATH=$PATH:/usr/local/cuda-8.0/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-8.0/lib64
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda-8.0/lib64

手动生效

sudo source /etc/profile

再次import caffe 仍然遇到相同的问题

执行以下命令：

sudo cp /usr/local/cuda-8.0/lib64/libcudart.so.8.0 /usr/local/lib/libcudart.so.8.0 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcublas.so.8.0 /usr/local/lib/libcublas.so.8.0 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcurand.so.8.0 /usr/local/lib/libcurand.so.8.0 && sudo ldconfig
 

ps. ldconfig命令是一个动态链接库管理命令，是为了让动态链接库为系统共享

后面又遇到问题：ImportError: libcudnn.so.5: cannot open shared object file: No such file or directory

执行以下命令：

sudo cp /usr/local/cuda-8.0/lib64/libcudnn.so /usr/local/lib/libcudnn.so && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcudnn.so.5 /usr/local/lib/libcudnn.so.5 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcudnn.so.5.0.5 /usr/local/lib/libcudnn.so.5.0.5 && sudo ldconfig

哇，后面发现我是用的root权限执行了import，，，哭～～～
