Your workflow is broken due to this unknown node:

Alright. I'll check it out. The workflow does work fine for me.
Could be due to the new Comfy update.

It was due to missing nvidia-vfx for the RTX Super Resolution node.

Might want to add the following for instructions, to install nvidia-vfx through this command: .\python_embeded\python.exe -m pip install nvidia-vfx --extra-index-url https://pypi.nvidia.com

Once it's installed, then the RTX nodes can be installed.

I take that back... still barfing errors:

@Smite79

I'm trying to reproduce this error but not getting these kinds of issues. Are you running a dev or some other branch of Comfy? Also are you updating via the manager or are you updating via the comfy native scripts? It also seems to be only affecting certain Windows users. I'll try a fresh installation on a windows specific machine again with updated Comfy and see if this error pops out. BTW check if it's the sage attention issue due to Triton.

Do you have Triton and Sage Attention installed?
If not, disable the Patch Sage Attention node by KJ and try again.

Also, thank you for troubleshooting the RTX node installation on the Windows Comfy Portable.

It may also have to do with the fact that I have a Blackwell GPU and there are reported issues of Blackwell GPU's not being compatible. I'm using a different workflow at the moment that's working well for me. I'm not seeing the need to pursue a resolution at this time.

ComfyUI is a stable release - 0.24. Drivers are 610.47.

@Smite79
Alright no problem, thank you.
I'm on Blackwell too and using this workflow on my PC and in cloud gpu rental deployments without any issues. I've shared it with other people also on Blackwell who are using it just fine.
Sorry i could not reproduce the issue, but it has to be some weird Comfy / python packages stack issue.
Gonna close this thread now.
