How to install cudatoolkit and cudnn on the jetson nano developer kit

[by.cmlla0107]

I need to use this GitHub project projeto. I’m inside the Conda environment where the necessary dependencies have been installed, but there are two missing ones that I can’t install at all. It always gives me this error: ResolvePackageNotFound: -cudnn=7.6.5 -cudatoolkit=12.1. I don’t know what else to do. It seems like my JetPack is outdated, but when I tried to start the Jetson Nano with a microSD card, the latest version didn’t work, so I had to download an older version which probably didn’t include CUDA.

Hi,

CUDA 12 is not avialbel for Nano.
Please check with the GitHub owner if they have a previous branch that supports CUDA 10.2.

Thanks.

Hi, now i have the 10.2 version of the cudatoolkit in my jetson nano. When i give the command “sudo apt list --installed | grep cuda” and/or “nvcc --version” return me this:

but when i give the command “conda env create -f environment.yml” of the project inside the folder depthmapper on the terminal, returns me “ResolvePackageNotFound: - cudatoolkit=10.2 -cudnn=8.2.1”.

My cudnn versions is 8.2.1. I see this when i give the command “cat /usr/include/cudnn_version.h | grep CUDA_MAJOR -A 2” or "“sudo apt list --installed | grep cudnn”, the latest returns me:

Hi

Have you checked with the sample owner to see if the sample can work on Jetson?

A common issue is that you might need to update the folder name if it is architecture related.
For example: /usr/lib/aarch64-linux-gnu/

Thanks.
