Hey @giemmecci,
I just documented in another thread what might be a solution for your problem. Your case looks different (as the error CUDA raises in your case is a RuntimeError and not an initialization error) - but it’s worth a shot (especially because re-installing NVIDIA drivers usually solves most of the CUDA issues anyways).
If you still have that instance paused, could you try the fix and let us know if that works? If that doesn’t solve it, feel free to come back with some logs. I would be happy to try and troubleshoot this (and curious to see if we can manage to replicate the issue).
Thanks,
Dennis.
