error: Command 'nvcc' not found, but can be installed with: after installing CUDA Toolkit 10.0

Question

I have installed cuda 10.0. I followed the procedure provided by this link but when I type the command nvcc --version it says nvcc is not installed!

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

sudo apt install nvidia-cuda-toolkit

I was wondering if you could help me. It has been quite a while I am struggling with having Cuda up and running. It has been failed for 4 times. I really got frustrated.

My system info is:

• Ubuntu 18.04.2 LTS
• GeForce GTX 1060/PCIe/SSE2

Please advise!

Solution

Check if nvcc is in the folder /usr/local/cuda-10.0/bin. If it is, something went wrong when you added the folder to your path, which is described in your linked manual as followed:

echo "export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}" >> ~/.profile
source ~/.profile

As the manual states, after that, echo $PATH should return some folders including the one above.

---

If the path and nvcc do not even exist, your installation failed. I found the installation via the .deb file very error prone and alwas suggest to install cuda from the sources, which worked for me every time on 6 different computers and Ubuntu versions without any hassle.

Use the installation guide provided here by eromod:

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt update

sudo ubuntu-drivers autoinstall

reboot

sudo apt install nvidia-cuda-toolkit gcc-6

nvcc --version

Remember to follow the post-installation steps here at docs.nvidia.com/cuda/cuda-installation-guide-linux/…. Otherwise even though you may have nvcc on your system, as it is not in the PATH it will not get picked up.
