hi, windows or just works on linux and macOS?

[Arclord]

I work on windows and it can't fully finish the line pip install . , it says ....linux..not support on this platform..blablabla
and when I try to startup the demo.py, it say no module worldgen.

I haven't tested it on Windows yet, but it should work if you install the packages correctly.
From your description, Looks like some of the packages are not supported on windows platform so your pip install . failed.
Could you please show the full error message?

[SoluisGroup]

I think you can only get as far as installing some packages where others wont work
ERROR: nunchaku-0.2.0+torch2.7-cp311-cp311-linux_x86_64.whl is not a supported wheel on this platform.
(worldgen) PS C:\worldgen>

[ZiYang-xie]

yes, so it's not officially supported on windows yet. But if you guys asking for an API, I might consider hosting one. thumbs up here. If more than 15 ppl, I'll do that.

I have everything compiled on Windows. Used this wheel:

"nunchaku @ https://github.com/nunchaku-tech/nunchaku/releases/download/v1.0.0dev20250904/nunchaku-1.0.0.dev20250904+torch2.9-cp311-cp311-win_amd64.whl",

and used the pytorch3d wheel from here:

https://miropsota.github.io/torch_packages_builder/pytorch3d/

I also built UniK3D-main from source, after changing the requirements.txt files to include: triton-windows instead of triton.

and made sure everything kept to pytorch 2.9 - CUDA 12.8

I also hit an issue with the path to the huggingface models, so i downloaded them with this snippet to fix a single-forwardslash-path-issue on windows.

from huggingface_hub import snapshot_download

# This downloads the repo to the cache and returns the local snapshot folder.
snapshot_dir = snapshot_download(
    repo_id="mit-han-lab/svdq-int4-flux.1-dev",
    # revision="main",            # or a specific tag/commit
    # local_files_only=False,     # set True if you already have everything offline
    # allow_patterns=["*.safetensors","*.json"],  # optionally filter files
)
print(snapshot_dir)  # path inside the cache
