CUDA 9.1 location on Ubuntu 18.04

Dear all,

I have installed CUDA on my Ubuntu 18.04 and can compile and run some CUDA programs,
when I run the command

nvcc -V

I have

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Nov__3_21:07:56_CDT_2017
Cuda compilation tools, release 9.1, V9.1.85

but when I enter the path:


I don’t see cuda directory.
I tried to enter this directory both from the terminal and from the Files window

How can I find a CUDA location?

Thank you

I ran ubuntu command:

locate cuda

Hope it’ll help anyone
