Nvcc --version returns nothing despite correct install

Accelerated Computing CUDA CUDA Setup and Installation

I properly installed CUDA 10.1 as per NVIDIA website instructions. However, I noticed two discrepancies. First, nvcc --version returns the following:

Command 'nvcc' not found, but can be installed with:

sudo apt install nvidia-cuda-toolkit

Also, nvidia-smi indicates that I have CUDA 10.2:

Should I be worried about this? If so, any solutions to fix it?

EDIT: The solution below is correct, but I got it to work by simply entering the export commands into terminal, rather than editing the /.bashrc file.

Hi @ajayp1

  1. Open terminal and write this command,

nano /home/username/.bashrc OR nano /home/$USER/.bashrc

  1. Inside there add the following: (dont forget to change your CUDA version)

export PATH=“/usr/local/cuda-8.0/bin:$PATH”
export LD_LIBRARY_PATH=“/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH”

Great, thanks. Should I be concerned at all that nvcc --version and nvidia-smi indicate two different versions of CUDA?
