Ubuntu 当初同时按照了 cuda9.0 和 cuda10.0，但因为是安装的是双系统windows10 + Ubuntu16.04,在C盘分割了 40G个给Ubuntu，安装2个cuda太过占存储空间,/dev/sda6 use%已经到90%多，需要删除一个多余的cuda10.0.

wu@wu-X555LF:~$cd /usr/local/cuda/bin

wu@wu-X555LF:/usr/local/cuda-10.0/bin$sudo uninstall_cuda_10.0.pl

sudo: uninstall_cuda_10.0.pl: command not found

在/usr/local/cuda/bin 目录下,有cuda 自带的卸载工具uninstall_cuda_10.0.pl

cd /usr/local/cuda/bin

sudo ./uninstall_cuda_10.0.pl

删除完cuda10.0，通过df -h查挂载情况：

wu@wu-X555LF:/usr/local/cuda-10.0/bin$ df -h
