# steps for installing CUDA:
|
|
|
|
1. Ensure that you have a compatible NVIDIA driver setup; either via the automatic selection process, or by choosing your specific nvidia driver stack:
|
|
`./NVIDIA-drivers.sh` or `sudo apt install nvidia-driver-470 -y`
|
|
|
|
2. Follow steps to download the network build of cuda from here: https://developer.nvidia.com/cuda-11.3.0-download-archive - these pull cuda 11.3
|
|
~~~
|
|
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
|
|
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
|
|
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/7fa2af80.pub
|
|
sudo add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/ /"
|
|
sudo apt-get update
|
|
~~~
|
|
|
|
3. Install the specific version of cuda you wish to use:
|
|
`sudo apt install cuda-11-3`
|
|
|
|
4. Note that you may need to pull additional dependencies, so review the apt install messages if it responds with "needs X but will not be installed"
|
|
For example, in my installation I needed to also pull relevant drivers to match with the Nvidia-530 driver bundle, which resolved the dependencies.
|
|
`sudo apt install cuda-11-3 cuda-runtime-11-3 cuda-drivers-530 libnvidia-extra-530`
|
|
|
|
5. install the nvidia-cuda-toolkit to use `nvcc` if you don't already have installed:
|
|
`sudo apt install nvidia-cuda-toolkit`
|
|
|
|
6. You may need to reboot your machine to ensure that drivers load properly (optional)
|
|
|
|
7. Then set your path so that `nvcc` will reference the new cuda build:
|
|
`echo "export PATH=/usr/local/cuda-11.3/bin:$PATH" >> ~/.bashrc`
|
|
|
|
8. Check that things are working properly:
|
|
`nvcc --version` #should point at the newly installed cuda build
|
|
`nvidia-smi`
|
|
|
|
|
|
# Troubleshooting:
|
|
- I have had some better success periodically using the RUNFILE option at the cuda download pages because it is self-contained.
|
|
You can point your shell (step 6) at the new install the moment it's available
|
|
- Note that `nvidia-smi` will print the *latest cuda version that the driver supports* not the version of cuda you have installed.
