解决方案：

sudo gedit ~/.bashrc

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:

/usr/local/lib:/usr/local/cuda-9.1/lib64:/usr/lib/x86_64-linux-gnu:/usr/lib/nvidia-390

export LIBRARY_PATH=${LIBRARY_PATH}:/usr/local/cuda-9.1/lib64:/usr/lib/x86_64-linux-gnu:/usr/lib/nvidia-390

source ~/.bashrc

提示：修改环境变量前务必确认libnvidia-fatbinaryloader.so.390.90的存在
