Running on macbook getting noise as output

[cchance27]

I'm using the comfy base workflow for image to video, downloaded standard t5 since gguf models dont have ltxv support yet, and rendered, got ~14s/it and looked like it was going great until, the output generated...

This is with pytorch nightly, latest comfyui, python 3.11.5

ComfyUI_00001.mp4

Anyone got any ideas where to start debugging this to find where it’s going wrong

It seems there are bugs with the nightly builds of Pytorch. Try downgrading to Torch 2.4.1, that helped me.

did you already open a pytorch nightly bug report, they're pretty quick to fix regressions if thats the case if so i'll confirm it once i test it with 2.4.1

Edit: I created the pytorch issue as it wasn't created yet... maybe post your confirmation when you get a chance
