# CUDA installation

TIP

You don’t need to use sudo to install CUDA Toolkit (opens new window) and cuDNN (opens new window).

# CUDA 12.4

In this example we will use ${HOME}/cuda-12.4.0 as our installation path.

Download CUDA installer:

wget https://developer.download.nvidia.com/compute/cuda/12.4.0/local_installers/cuda_12.4.0_550.54.14_linux.run

Update permissions:

chmod +x ./cuda_12.4.0_550.54.14_linux.run

Run the installation (takes a few quiet minutes):

./cuda_12.4.0_550.54.14_linux.run \
  --silent \
  --toolkit \
  --installpath=${HOME}/cuda-12.4.0 \
  --no-opengl-libs \
  --no-drm \
  --no-man-page && echo Success || echo Fail

Cleanup installation files:

rm -v cuda_12.4.0_550.54.14_linux.run

# Install cuDNN for CUDA 12.4

Download cuDNN (opens new window) package:

wget https://developer.download.nvidia.com/compute/cudnn/redist/cudnn/linux-x86_64/cudnn-linux-x86_64-8.9.0.131_cuda12-archive.tar.xz

Extract the cuDNN package into our cuda installation:

tar -xvf cudnn-linux-x86_64-8.9.0.131_cuda12-archive.tar.xz --strip-components=1 -C ${HOME}/cuda-12.4.0 && echo Success || echo Fail

After extraction, remove the package:

rm -v cudnn-linux-x86_64-8.9.0.131_cuda12-archive.tar.xz

# Create activation script for CUDA 12.4

TIP

In the activation script have used the CUDA installation directory from our example above (${HOME}/cuda-12.4.0)

Create activation script by running the code below:

cat <<\EOF > ~/activate-cuda-12.4.sh

export CUDA_HOME=${HOME}/cuda-12.4.0

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 12.4

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

source ~/activate-cuda-12.4.sh

# Test commands

Run test commands to confirm that your installation was successful:

which nvcc

nvcc --version

The expected output:

/home/ubuntu/cuda-12.4.0/bin/nvcc
