Step 2: Install Application

Here are the steps to install Jan on Linux based on your Linux distribution:

Install Jan using either dpkg or apt-get:

dpkg

# Install Jan using dpkg
sudo dpkg -i jan-linux-amd64-{version}.deb

apt-get

# Install Jan using apt-get
sudo apt-get install ./jan-linux-amd64-{version}.deb
# where jan-linux-amd64-{version}.deb is the path to the Jan package

# Custom installation directory
$XDG_CONFIG_HOME = /home/username/custom_config
or
# Default installation directory
~/.config/Jan/data

See Jan Data Folder for more details about the data folder structure.

GPU Acceleration

Once Jan is installed and you have a GPU, you can use your GPU to accelerate the model's performance.

Step 1: Verify Hardware & Install Dependencies

1.1. Check GPU Detection

To verify that your system recognizes the NVIDIA GPU:


lspci | grep -i nvidia

1.2. Install Required components NVIDIA Driver:

  1. Install NVIDIA Driver (opens in a new tab) for your GPU (NVIDIA driver 470.63.01 or higher).
  2. Verify installation:

nvidia-smi

Expected output should show your GPU model and driver version.

CUDA Toolkit:

  1. Download and install CUDA toolkit (opens in a new tab) (CUDA 11.7 or higher)
  2. Verify installation:

nvcc --version

Linux Additional Requirements:

  1. Required packages are installed:

sudo apt update
sudo apt install gcc-11 g++-11 cpp-11

  1. Set up CUDA environment:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64

See detailed instructions (opens in a new tab).

Step 2: Enable GPU Acceleration

  1. Navigate to Settings () > Advanced Settings
  2. At GPU Acceleration, toggle on and select your preferred GPU(s)
  3. App reload is required after the selection

While Vulkan can enable Nvidia GPU acceleration in the Jan app, CUDA is recommended for faster performance.
