When I habitually installed CUDA and CUDANN, I found that CUDANN was missing. I couldn’t even find any information about it on the official website, and there was no announcement. Let’s take a look at the complaints.
To be honest, CUDANN was really annoying at first. I had to download it and copy it.
Now you only need to install cuda directly, and the installation will be successful.
CUDA Toolkit 12.2 Update 2 Downloads | NVIDIA Developer
You only need to install CUDA. There is no need to install CUDANN, it is already configured.
