libcudart.so.8.0: cannot open shared object file: No such file or directory
所需的libcudart.so.8.0如果正确安装的话，以下两种方法同理：
sudo ldconfig /usr/local/cuda-9.2/lib64
(转自libcudart.so.8.0: cannot open shared object file: No such file or directory)
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-8.0/lib64。如果仍然不行，再尝试执行:
export PATH=$PATH:/usr/local/cuda-8.0/bin
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda-8.0/lib64
source /etc/profile
若需要将文件移到根目录下，需要在命令前面加上sudo
