Hi, I am trying to install cudnn9 to match with my CUDA 11.8 installed.
as per the link, it says cudnn9 is compatible with CUDA 11.8: link

I am facing an issue whereby the steps provided in the link below cause the system to install cudnn9.4.0 with CUDA 12.6:

How can I install cudnn 9.4.0 to be statically linked with CUDA11.8 for my Jetson Orin Nx ?

my system versions:
Ubuntu 20.04
Jetpack 5.1.3, L4T: 35.5.0
CUDA 11.8.89

Below is the current install information from the steps to install cudnn9
ii cudnn9-cuda-12 9.4.0.58-1 arm64 NVIDIA cuDNN for CUDA 12
ii cudnn9-cuda-12-6 9.4.0.58-1 arm64 NVIDIA cuDNN for CUDA 12.6
ii libcudnn9-cuda-12 9.4.0.58-1 arm64 cuDNN runtime libraries for CUDA 12.6

Hi,

We don’t have a combination of cuDNN 9 + CUDA 11.8.

JetPack 5 only supports the CUDA package upgrade.
For other packages, ex cuDNN or TensorRT, the upgradable feature is added in the JetPack 6.

Please note that the JetPack 6 supports CUDA 12.2+, no CUDA 11 is available.

Thanks.

could you please confirm and clarify what the contents in the links I sent in relation to the compatibility of the libraries?

cuDNN9 corresponds to cuDNN 9.4.0. correct?

from the support matrix cuDNN 9.4.0 + 11.x , where it shows 11.8 as compatible
