Nvidia driver issue in CUDA installation on Ubuntu 18.04

Hi,

I was trying to install Cuda 10.0 .deb (local) installation for V100 but there seems to be issues in driver installation. The CUDA installation was successful but not able to communicate with the GPU. I have attached the log file. Also in the log file it says “The package that is already installed is named nvidia-440-440.” but I could not locate any file/package named nvidia-440-440 in the system. I have attached some more details in the image. Appreciate any help in advance.
