nvcc --version command says nvcc is not installed
I have installed cuda8.0, the latest version. I followed the procedure provided by Nvidia; but, when I type the command nvcc --version it says nvcc is not installed!
What do I do now?

The problem is [ based on the link you provided] you haven't added it the .bashrc. file so it can be seen:
From the terminal:
nano /home/username/.bashrc # or nano /home/$USER/.bashrcInside there add the following: (replace
cuda-8.0with your version)export PATH="/usr/local/cuda-8.0/bin:$PATH" export LD_LIBRARY_PATH="/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH"Then do the following to save and close the editor:
On you keyboard press the following: ctrl + o --> save enter or return key --> accept changes ctrl + x --> close editorNow either do
source .bashrcorclose and open another terminalNow run
nvcc --version
Information:
.bashrc: is the file read by theterminalbefore opening and its found in the/home/$USERdiretory of the user in question.- the
.before the file means its hidden from view unless you instruct you file manager to showhiddenfiles
The above solution by @George Udosen is fine. If you want to save the manual procedure, you can automize it by the following:
1.create a file "add_to_bashrc"
export CUDA_HOME=/usr/local/cuda
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64
export PATH=$PATH:$CUDA_HOME/bin2.create a shell script "automate.sh":
(... some installation procedure ...)
cat add_to_bashrc >> ~/.bashrc
. ~/.bashrcThen you just need to run your shell script
sh automate.shDon't forget to check if the CUDA's shortcut (symLink) works correctly. Simply execute:
ls /usr/local/cudaThe answer from @George Udosen is perfect.
Just for increment it, you can also export to /usr/local/cuda which is a symbolic link to /usr/local/cuda-10.1, based on this answer. So, you can also write:
export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}$
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
