comfyui-3d-pack still failed import ? please help

[masaomo]

windows 10 , pytorch 2.7.0 (clone from -dev version already) and all its cs dependencies is completed

and the problem is comfyui-3d-pack nightly (0.1.3) is still import failed, already try fix also failed,,

[masaomo]

also try load hunyuan3d_v2_mv_turbo

there nodes in red, is comfyui3dpack is not the same with hunyuan3d-2mv-turbo model? (hunyuan3d v2 shapegen, comfy3d multi background, comfy3d load hunyuan3d... , comfy3d hunyuan3d v2 paint...)

I am new just install done through,

[DenisKochetov]

@masaomo could you please send me logs of your errors and screenshots maybe

@masaomo

You’re hitting a version conflict between peft and transformers.

Please switch to the dev branch — we’ve pinned compatible versions there.

Then reinstall deps:

pip uninstall -y peft diffusers transformers accelerate
pip install peft==0.17.1 diffusers==0.31.0 transformers==4.46.2 accelerate==1.1.1

That should fix it 👍
