Hi, if you have problem using pre-build wheels for kiuikit library then please try following: pip install git+https://github.com/ashawkey/kiuikit.git

Same problem here.

I've tried:

pip install git+https://github.com/ashawkey/kiuikit.git pip install kiui pip install kiui[full]

and still not import the 3D-Pack with the same identical errors that @WhiteKnight666 wrote.

I installed kiui through the experimental option "install PIP packages" in the manager by pasting "kiui" (no quotes) into the dialogue box and clicking OK. That fixed the original error however I'm now getting the following:

If you didn't get any error when install kiuikit then it probably means your comfy python environment is not you OS default python environment and you installed it into OS default python environment, you should run:

[Path to your comfy python.exe] -s -m pip install git+https://github.com/ashawkey/kiuikit.git e.g. C:\Users\reall\Softwares\ComfyUI_windows_portable\python_embeded\python.exe -s -m pip install git+https://github.com/ashawkey/kiuikit.git

If you install this via comfyui-manager, you'll need to manually install the prebuilt wheels appropriate to your environment afterwards eg. for windows/python3.11/cuda 12.1

I've also tried what suggested @maxious but i get always the message for each line

XXXXXX is already installed with the same version as the provided wheel. Use --force-reinstall to force an installation of the wheel.

I guess this repo is broken for many users, I tried for hours and hours to make it work, reinstalled everything from scratch, made new envs and it simply doesn't work

I have the same issue @Pupazzzz have. Installed wheels, and got the import procedure fail.

both of those pre builds are currently missing?

I often install nodes directly using terminal instead of comfy manager, not all nodes can be properly managed by manager ;) things like "ModuleNotFoundError: No module named 'kiui'", you can try install it in your comfy environment folder: In your comfy's environment folder (folder name should be python embeded), find ...\Lib\site-packages, right-click mouse, find option" open in terminal" and open it, type"pip install kiui", wait till the installation done. Restart comfyUI and it should work.

Having this same issue. I tried CoraAI's suggestion above:

And still not having any luck. I get an import error in ComfyUI about kiui.

Are you using custom env? I use anaconda to manage envs of several comfy packs, If so then try activate env in terminal before any moves, also check out the corresponding environment variables path, sometimes it can't be set properly and need to be modified manually, I must say that I'm not a programmer, if the issue exists still, you'd better post with error codes in order to get professional help here.

Feb 12 '25 02:02 CoraAI

Hey @CoraAI - I'm not using custom envs. Just wanted to add to the conversation as another person having this issue. I didn't mean to sound like I wasn't appreciative of your suggestion, just hoping to make it clear that people are still experiencing this problem.

Is there a solution to the problem 3d pack does not work and I have an error ModuleNotFoundError: No module named 'kiui'
