Hi @Moodrabbit what version of CUDA do you have installed? you may need to update it.

@Moodrabbit - You don’t need to install CUDA with AI Workbench.

It’s handled at the container level.

If you aren’t using Workbench, then you might be better off posting in this forum: Latest Deep Learning (Training & Inference)/Frameworks topics - NVIDIA Developer Forums

Seems like you aren’t using Workbench.

Can you please post in an appropriate forum?
