GLIGEN basic examples workflow error occurred when executing KSampler

[huaibi2008]

Your question

I used the GLIGEN workflow from Basic Examples.
This problem arises when executing to Ksapler.
No custom node.

Logs

Error occurred when executing KSampler:

Expected all tensors to be on the same device, but found at least two devices, cuda:0 and cpu! (when checking argument for argument tensors in method wrapper_CUDA_cat)

I think you have either an IGPU that somehow is interfering with your GPU or some setting turned on that makes it think you have 2 devices, it does not know which to choose. Is what I make out of this.

[huaibi2008]

thank you first。but my cpu have no IGPU。and I use \ComfyUI\ComfyUI\main.py" --windows-standalone-build --cuda-device 0 --listen 192.168.31.125 --port 8188 --gpu-only to start comfyui. I still don't know how to fix it.

After looking into it you might have ran out of Vram which made it try probably to offload on your CPU and Ram for some reason and then probably later down the line there's code that does not accept 2 devices GPU + CPU as an input.

Try making your image smaller and not overloading Vram see if that works.
