CUDNN Installation​

CUDNN Download​

  1. First you need to click the official website download link：https://developer.nvidia.com/cudnn-downloads?target_os=Windows&target_arch=x86_64&target_version=Agnostic&cuda_version=12, select the option in the red box at the bottom as shown in Figure 9, click cudnn after entering, then select the windows version, and then select the corresponding cudnn according to the cuda version and download it, as shown in Figure 10.

  1. Note: After configuring the environment variables, you need to restart the computer. At this point, the installation of cuda and cudnn is complete.

Solutions to CUDA Installation Failure​

  1. An error occurred during the CUDA installation process:
  2. Solution: After the CUDA version is downloaded, double - click to install directly and select the default installation path.
  3. Click "Agree and Continue".
  4. Select the custom mode.
  5. When choosing components, uncheck Nsight VSE and Visual Studio Integration in CUDA, then click "Next" and the installation will be successful.
