I type echo $LD_LIBRARY_PATH and got /usr/local/cuda-9.0/lib64 but when I check my bashrc file they are not there. Where are they ?

          They should be in the ~/.profile file. If not, add the following to the bottom of your ~/.profile file:



          # set PATH for cuda 9.0 installation
          if [ -d "/usr/local/cuda-9.0/bin/" ]; then
          export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}
          export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

          • thank you. i am not familiar with the syntax. does this mean LD_LIBRARY_PATH will point to multiple folders ? thats what the colon seem to suggest.

            @Kong The : are used as separators in the PATH environment. So, the above adds the /usr/local/cuda-9.0/bin folder to your PATH statement if that folder exists.

            @Kong Oh, and the existing PATH statement should be in the /etc/environment file.

          • tyvm, i see the PATH statement. But what about the LD_LIBRARY_PATH ? I dont see it in .bashrc as well as environment

            @Kong The LD_LIBRARY_PATH should be in the same area as ~/.profile. See the second export line in my answer.

          They should be in the ~/.profile file. If not, add the following to the bottom of your ~/.profile file:



          # set PATH for cuda 9.0 installation
          if [ -d "/usr/local/cuda-9.0/bin/" ]; then
          export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}
          export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
          fi

            @Kong The : are used as separators in the PATH environment. So, the above adds the /usr/local/cuda-9.0/bin folder to your PATH statement if that folder exists.
