Very frustrating this hasn't been addressed, but I understand people have lives outside of the programs they are creating - and it looks like the author hasn't updated anything in quite a while.

I'm getting the same error, have you found a fix by chance?

[Ainaemaet]

Ok, so after looking through issues on the main ComfyUI repo, it looks like @comfyanonymous (ComfyUI creator) deprecated some nodes, and in the process broke compatibility for a number of custom_nodes.

He reverted some changes, and most custom nodes work again, but it looks like this one still needs to be updated!

@crystian can you please update to allow compatibility with new version of ComfyUI?

[crystian]

I use the latest version of nvidia drive 555.85, and reinstall all nodes, and works! ¯_(ツ)_/¯

can be the language? which language do you use? I use English and spanish (windows)

Hello, same problem here , node re-installation does not work, ComfyUi and All nodes updated, RTX 3090 / Nvidia 555.85 / Win 11 French & English. This is the only node, but essential, that doesn't work for me, very happy if we could find a solution.

gpuopenanalytics/pynvml#53 it's NVML bug, just wait for driver update or rollback driver
