Unable to re-run the notebook

Hi, I was trying to re-run my notebook but I’m getting the following error message when I try to run a segmentation model using docker

I’ve tried looking for solutions online, but nothing worked. I didn’t make any change to the environment or my virtual machine, and the same code works just fine on another virtual machine on the same Google Cloud project.

Any clue of what could be the issue?

Thanks!

With the log it looks like the problem is with the GPU. Either outdated drivers or a general configuration error. Is your VM a managed notebook instance?

@giemmecci can you provide the details about what is going on:

Yes, it’s definitely something with the GPU; I’ve tried looking for the error online, and people seem to fix it either by re-installing PyTorch (which is not the solution for me since I haven’t installed it on my VM; the error arises when trying to apply a segmentation model using docker) or reloading the NVIDIA kernel.
I’m not sure if this will answer your question, but I’m launching the notebook from the AI Platform section (project: idc-external-005, instance gm-tf2).

Thank you for your help and your time!

Since those are managed instances - you can just create a new one and check if it works in the new instance. If it does work my guess would be that the error you see on an older instance is related to the recent merger of the AI Notebooks into the newer Vertex AI product in Google Cloud.

Thanks for the suggestion, but unfortunately it didn’t work; I’ve created another instance with the same characteristics as my older one, but I’m still getting the same error message:

I’ve updated the notebook to make the test shorter (reduced the number of MRIs that are downloaded)
