The installation path of CUDA can be found in the previous screenshot, or you can check the environment variables of your computer. The default installation path is as follows:
When copying, you will see that there is a folder with the same name as cuDNN in the installation directory of CUDA. Don't worry, just copy it directly. The configuration files in the folder with the same name as cuDNN after unzipping will be added to the folder with the same name in the CUDA installation directory. [It is still recommended to copy the contents of the folders to the corresponding folders separately]
cuDNN is actually a patch for CUDA, optimized for deep learning operations. Then add the environment variables.
First, copy the files with the same name as cudnn to the location where cuda is installed.
