Import Failed on windows. #4

NegInfinity · 2025-05-20T10:42:02Z

I've spent some time trying to get it to run on windows - using portable ComfyUI and venv-based comfyui with no luck.

Import fails with this sort of message:

  File "C:\Imggen\ComfyUI-venv\ComfyUI\nodes.py", line 2131, in load_custom_node
    module_spec.loader.exec_module(module)
  File "<frozen importlib._bootstrap_external>", line 999, in exec_module
  File "<frozen importlib._bootstrap>", line 488, in _call_with_frames_removed
  File "C:\Imggen\ComfyUI-venv\ComfyUI\custom_nodes\ComfyUI-Step1X-3D\__init__.py", line 1, in <module>
    from .nodes import LoadStep1X3DGeometryModel, LoadStep1X3DGeometryLabelModel, LoadStep1X3DTextureModel, LoadInputImage, GeometryGeneration, GeometryLabelGeneration, LoadUntexturedMesh, TexureSynthsis, SaveUntexturedMesh, SaveTexturedMesh
  File "C:\Imggen\ComfyUI-venv\ComfyUI\custom_nodes\ComfyUI-Step1X-3D\nodes.py", line 8, in <module>
    from step1x3d_texture.pipelines.step1x_3d_texture_synthesis_pipeline import (
ModuleNotFoundError: No module named 'step1x3d_texture'

Looking through the code the problem seems to stem from modules trying to import their parents. For example, ComfyUI-Step1X-3D/step1x3d_texture/pipelines/step1x_3d_texture_synthesis_pipeline.py tries to import from step1x3d_texture which is its parent. It happens here:

from step1x3d_texture.models.attention_processor import (
    DecoupledMVRowColSelfAttnProcessor2_0,
)

And import is done without specifying relative path. step1x3d_texture exists 2 or 3 levels above synthesis_pipeline, it is not one of the search paths, so import fails.

Trying to switch all import statements to relative addressing ultimately fails when some of the files within step1x3d use decorators.

@step1x3d_geometry.register("michelangelo-autoencoder")

Would be nice if this got fixed. Surely the author of the custom node ran this somehow so it should work. But it doesn't.

Windows scripts I used to init comfyui:

init-venv.bat (step1):


py -3.12 -m venv venv

set ACT = %~dp0venv/Scripts/activate.bat
set DEACT = %~dp0venv/Scripts/deactivate.bat

call %ACT%

python --version

call %DEACT%

run1.bat (step2):


set VENV="%~dp0venv"
set START_VENV="%VENV%\Scripts\activate.bat"
set STOP_VENV="%VENV%\Scripts\deactivate.bat"

call %START_VENV%

python --version

python -m pip install --upgrade pip

pip install egg wheel

pip install torch==2.5.1 torchvision==0.20.1 torchaudio==2.5.1 --index-url https://download.pytorch.org/whl/cu124

cd ComfyUI

pip install -r requirements.txt

pip install torch-cluster -f https://data.pyg.org/whl/torch-2.5.1+cu124.html

call %STOP_VENV%

init-step1.bat (step3):


set VENV="%~dp0venv"
set START_VENV="%VENV%\Scripts\activate.bat"
set STOP_VENV="%VENV%\Scripts\deactivate.bat"

call %START_VENV%

cd ComfyUI\custom_nodes 

if not exist ComfyUI-Step1X-3D (
	git clone https://github.com/Yuan-ManX/ComfyUI-Step1X-3D.git
)

cd ComfyUI-Step1X-3D

pip install torch==2.5.1 torchvision==0.20.1 torchaudio==2.5.1 --index-url https://download.pytorch.org/whl/cu124
pip install -r requirements.txt
pip install torch-cluster -f https://data.pyg.org/whl/torch-2.5.1+cu124.html

cd step1x3d_texture/custom_rasterizer
python setup.py install
cd ../differentiable_renderer
python setup.py install
call %STOP_VENV%

run2.bat (step4, running the environment):


set VENV="%~dp0venv"
set START_VENV="%VENV%\Scripts\activate.bat"
set STOP_VENV="%VENV%\Scripts\deactivate.bat"

call %START_VENV%

python -s ComfyUI\main.py --windows-standalone-build

call %STOP_VENV%
