• Ensure there is enough space in /tmp and that the installation package is not corrupt

刚开始安装./cuda_12.1.1_530.30.02_linux.run时， /所在的/dev/sdb7所剩空间越来越小，最终安装失败，提示 Ensure there is enough space in /tmp and that the installation package is not corrupt。 所以必须先扩展/所在的硬盘容量

按这个步骤安装，一般不会出问题: ubuntu18.04上cuda及cudnn安装
