if you are using InstantX Flux ControlNet Loader or any other ControlNet just replace it with a comfyUI loader and then it should work Load ControlNet Model
Try reducing the Resolution.
@fani-kiran thanks this somehow works, at least i get further down the workflow, but then i get different other errors like:
- SaveGLB zero-size array to reduction operation maximum which has no identity
- VoxelToMesh integer modulo by zero
exact same issue here, was working perfectly fine until after ~10 gens it stopped working whatever i did, decreasing resolution fixed it but it affects the quality wich is a bit annoying
for anyone still looking how to solve this, i noticed after a while that i had a few python scripts running in the background still even though i had closed comfyUI. after stopping them and trying again the error disappeared, i'm not really sure why but i guess there's something that's not stopping the scripts correctly causing an error when they accumulate
use .bat file without "--use-sage-attention" or "--fast fp16_accumulation" this fixes : "zero-size array to reduction operation maximum which has no identity"
I had the same and dropped resolution and hard restarted the instance to resolve it. Looks like my setup is mostly identical to OPs.
Had this issue running the template HunyuanV 1.5 i2v workflow just now.
Will try reducing the resolution.
Ok, actually turning off "Display Animated Previews While Rendering" in the VHS (Video Helper Suite) settings resolved it.
This is the second time tonight that toggle broke a WF for me (different errors).
@Kosinkadink @AustinMroz
(Perhaps related to https://github.com/comfyanonymous/ComfyUI/commit/b9070857092a78cc952d70025fdcc0ff540d96ec )
not enough values to unpack (expected 2, got 1)
Did you try going into settings, settings for the Video Helper Suite, and disabling Animated Previews? Try that and see if it gets passed then the error.
Works here, but yea still need a solution so Video Helper Suite isn't taking over previews @Kosinkadink
Same here - not enough values to unpack (expected 2, got 1) Reduced the Resolution by half in K Sampler but to no avail. Where is the Video Helper Suite ? I'm not seeing it ?
@LoCo1 I was able to get this working by reducing resolution from 4096 to 2048 in the node EmptyLatentHunyuan3Dv2, not KSampler
I also do not see that Video Helper Suite thing for what it's worth, maybe it's a plugin we don't have?
