"Prompt has no properly connected outputs Parsing error" while running the workflow json

[Natotela]

any notions what is missing? only changed the model + vae to fit my paths

[TinyTerra]

Thanks for pointing this out.. I've made some changes to the pipeKSampler since I made the workflow json, so it is loading them with the old layout.

If you do a git pull now, I've updated the workflow json and it shouldn't give you any issues now.

[Natotela]

Thanks master! next on our debug questionnaire ;-) Queuing the prompt starts with

got prompt

which doesn't stop the process, alas later on when we reach the imageRemBG, it gets cancelled

when I add manually add the ttn imageRemBG node it lacks any connectors (no in nor out), and writes a default
"RemBG is not installed", "https://github.com/danielgatis/rembg"

temp fix is sending the 2nd pipKsampler's image to Image to Mask node + directly to the sequential Image OverLay node.

[TinyTerra]

RemBG hasn't installed properly.. or Isn't being found. Can you try manually installing it and see if that helps? navigate to the

....\Comfy\python_embeded\Lib\site-packages

folder in cmd, and run

"../../python.exe" -m pip install rembg[gpu]

[Natotela]

not sure if FN16-ComfyUI-nodes is related but same rembg theme, as I load comfyUI:

seems to be an issue with comfy not being able to find the rembg module. if it is breaking FN16-ComfyUI-nodes as well. out of curiosity, what version of python do you have the python_embeded folder?

[Natotela]

StandAlone comfyUI version

F:\newprogz\comfyui_windows_portable> .\python_embeded\python.exe -V
Python 3.10.9

[TinyTerra]

when you run pip install rembg, are it and all of its dependencies installed inside the comfy python_embeded venv?

[Natotela]

interesting, it found it on the system's site-packages, but it wasn't in the stand-alone dir I wonder why it installs it on the system-wide's python. Perhaps I shouldn't work in a standalone version

[TinyTerra]

rembg seems to be the main contributing factor.. I'm not too sure why it struggles to install correctly.

Maybe try uninstalling it from the system-wide packages, and re-run comfy

[Natotela]

I tried copying rembg from appdata\roaming\python\python310\site-packages\ to comfyui_windows_portable\python_embeded\lib\site-packages\ then it gave an error of no module found each time I ran comfy, and I copied the same each missing module. CURRENTLY - the imageRemBG node is actually working (as in doesn't send me to install the rembg link) But, when I prompt I get this:

Traceback (most recent call last):

AttributeError: module 'folder_paths' has no attribute 'get_save_image_path'

[TinyTerra]

the get_save_image_path function was added to the folder_paths.py (from the base comfy app) three days ago i think.. so updating comfy should resolve that one

[Natotela]

Everything works ! all it took was a little bit frustration and a little more resilience, thanks a lot! keep up rocking!

[TinyTerra]

Always the way :p Glad its working now!
