Hello, I have a Jetson Nano installed in a remote location, with ssh but no physical access.
Here are some details:

I have just remotely resintalled Cuda, DeepStream and other optional packages with SDK Manager but when trying to reach the CUDA device I’m getting the following error.

/usr/local/cuda/samples/1_Utilities/deviceQuery$ ./deviceQuery
./deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 100
-> no CUDA-capable device is detected
Result = FAIL

Any suggestions?

Moving to Jetson Nano forum.

Hi,

Have you manually set the CUDA_VISIBLE_DEVICES value?

Thanks.

Thanks for the quick reply, I have tried using

export CUDA_VISIBLE_DEVICES=0

and also 1, but still same result on the ./deviceQuery.
Any other idea?

Well, found out that the kernel modules were missing, after copying form another unit and rebooting the CUDA device was detected.
Thanks for the help!

Thanks for the update.
Good to know it works now.

Had a similar issue, which turned out to be a permissions issue. Look at adding the user to the dev group ‘video’. (and don’t forget to logout/login)
