Installing cuDNN on Ubuntu 22.04

Step 1: Download cuDNN

1. Go to https://developer.nvidia.com/cudnn
2. Sign in to your NVIDIA Developer account (or create one if needed)
3. Navigate to Downloads
4. Find and download cuDNN v9.6.0 for Ubuntu 22.04 (.deb package)

Step 2: Install cuDNN

Run these commands in order:

# Install the downloaded package
sudo dpkg -i cudnn-local-repo-ubuntu2204-9.6.0_1.0-1_amd64.deb

# Copy the keyring
sudo cp /var/cudnn-local-repo-ubuntu2204-9.6.0/cudnn-*-keyring.gpg /usr/share/keyrings/

# Update package list
sudo apt-get update

# Install cuDNN
sudo apt-get -y install cudnn

# Install CUDA 12 specific package
sudo apt-get -y install cudnn-cuda-12

Step 3: Verify Installation

# Check if cuDNN is installed correctly
find /usr -name "libcudnn.so*"

Note: Direct download links won't work - you must download through NVIDIA's website after logging in.
