Mixing cuda 10 and cuda 11.4 on Orin

Hello! I’m running into an issue with having cuda 10.0 and cuda 11.4 in a docker container (l4t-jetpack:r35.4.1 as my base) on a Jetson Orin with Jetpack 5.1.2. I have the newest Nvidia-container-toolkit installed on the device. When running my application I must install nvidia-compute-535 to get the cuda 10 side of things working. But that breaks the gstreamer plugins (nvbufsurftransform:cuInit failed : 100). Not installing nvidia-compute-535 leads to cuda 10 not loading at all.

I’ve narrowed it down to the symlink in /usr/lib/aarch64-linux-gnu/libcuda.so. When compute is installed then it’ll point to libcuda.so.535.x.y.z, but without it it’ll point to /usr/lib/aarch64-linux-gnu/tegra/libcuda.so. I’m just looking for some advice on what might be happening here and how I can get around it.

Thanks!

Hi,

Is your application built with CUDA 10?
If yes, please recompile the app. CUDA 10 is not available on the Orin device.

Thanks.
