CUDA installation ​

TIP

You don’t need to use sudo to install CUDA Toolkit and cuDNN.

CUDA 13.2 ​

In this example we will use ${HOME}/cuda-13.2.0 as our installation path.

bash
cd "${HOME}"

Download CUDA runfile installer:

bash
wget https://developer.download.nvidia.com/compute/cuda/13.2.0/local_installers/cuda_13.2.0_595.45.04_linux.run

Update permissions:

bash
chmod +x ./cuda_13.2.0_595.45.04_linux.run

Start the runfile installation (takes a few quiet minutes):

bash
./cuda_13.2.0_595.45.04_linux.run \
  --silent \
  --toolkit \
  --installpath=${HOME}/cuda-13.2.0 \
  --no-opengl-libs \
  --no-drm \
  --no-man-page && echo Success || echo Fail

Cleanup installation files:

bash
rm -v cuda_13.2.0_595.45.04_linux.run

Install cuDNN for CUDA 13.2 ​

Download cuDNN package:

bash
wget https://developer.download.nvidia.com/compute/cudnn/redist/cudnn/linux-x86_64/cudnn-linux-x86_64-9.20.0.48_cuda13-archive.tar.xz

Extract the cuDNN package into our cuda installation:

bash
tar -xvf cudnn-linux-x86_64-9.20.0.48_cuda13-archive.tar.xz --strip-components=1 -C ${HOME}/cuda-13.2.0 && echo Success || echo Fail

After extraction, remove the package:

bash
rm -v cudnn-linux-x86_64-9.20.0.48_cuda13-archive.tar.xz

Create activation script for CUDA 13.2 ​

TIP

In the activation script have used the CUDA installation directory from our example above (${HOME}/cuda-13.2.0)

Create activation script by running the code below:

bash
cat <<\EOF > ~/activate-cuda-13.2.0.sh

export CUDA_HOME=${HOME}/cuda-13.2.0

export PATH=$CUDA_HOME/bin:$PATH
export LD_LIBRARY_PATH=$CUDA_HOME/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$CUDA_HOME/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$CUDA_HOME/extras/CUPTI/lib64:$LD_LIBRARY_PATH
export CUDAToolkit_ROOT_DIR=$CUDA_HOME
export CUDAToolkit_ROOT=$CUDA_HOME

export CUDA_TOOLKIT_ROOT_DIR=$CUDA_HOME
export CUDA_TOOLKIT_ROOT=$CUDA_HOME
export CUDA_BIN_PATH=$CUDA_HOME
export CUDA_PATH=$CUDA_HOME
export CUDA_INC_PATH=$CUDA_HOME/targets/x86_64-linux
export CFLAGS=-I$CUDA_HOME/targets/x86_64-linux/include:$CFLAGS
export CUDAToolkit_TARGET_DIR=$CUDA_HOME/targets/x86_64-linux

EOF

Set environment variables for CUDA 13.2 ​

From now one you can easily load your cuda variables by sourcing activation script:

bash
source ~/activate-cuda-13.2.0.sh

Test commands ​

Run test commands to confirm that your installation was successful:

bash
which nvcc

nvcc --version

The expected output:

text
/home/ubuntu/cuda-13.2.0/bin/nvcc
