Error while installing

[kakachiex2]

I got this error during installation:

note: This error originates from a subprocess, and is likely not a problem with pip.

I haven't encountered this problem before. But a few things you could try:

1. Install using Miniconda
2. Install with ComfyUI's embed python env on Windows by using chocolatey
3. Clear the cache and do a clean re-install ComfyUI and follow the Install Instruction Closely

I'll optimize the install process a bit this weekend, since this appears to be where many users have problems

[vKreuziger]

I've had the same issue, likely resulting from missing dependencies. I was able to fix it under Linux (WSL Ubuntu) since binaries for pytorch3d were available (building didn't work there either). Any streamlining of the process would be much appreciated!

[kakachiex2]

I have ComfyUI installed with venv enviroment and lots of extension, I install Miniconda and follow the process correctly the only problems was wen building pythorch3d is there a way to install pytorch3d binaries in windows; and I don't wants to install a fresh version of comfy, men I don't have much space and my ComfyUI work really stable.

[kakachiex2]

I found a way to install pre-build binaries if you point me were to install it I do the process

[kakachiex2]

I install everything from zero and I get the same error look like it related to the compiling process.

• first with the install .bat get the same error

• manually plan b: the same error Error at startup:: okresearch/pytorch3d.git@stable Collecting git+https://github.com/facebookresearch/pytorch3d.git@stable Cloning https://github.com/facebookresearch/pytorch3d.git (to revision stable) to c:\users\rafae\appdata\local\temp\pip-req-build-3pvc5rky Running command git clone --filter=blob:none --quiet https://github.com/facebookresearch/pytorch3d.git 'C:\Users\rafae\AppData\Local\Temp\pip-req-build-3pvc5rky' Running command git checkout -q 2f11ddc5ee7d6bd56f2fb6744a16776fab6536f7 Resolved https://github.com/facebookresearch/pytorch3d.git to commit 2f11ddc5ee7d6bd56f2fb6744a16776fab6536f7 Preparing metadata (setup.py) ... done Collecting fvcore (from pytorch3d==0.7.5) Using cached fvcore-0.1.5.post20221221-py3-none-any.whl Collecting iopath (from pytorch3d==0.7.5) Using cached iopath-0.1.10-py3-none-any.whl Requirement already satisfied: numpy in k:\comfyui\comfyui_ex\python_miniconda_env\comfyui\lib\site-packages (from fvcore->pytorch3d==0.7.5) (1.26.3) Collecting yacs>=0.1.6 (from fvcore->pytorch3d==0.7.5) Using cached yacs-0.1.8-py3-none-any.whl (14 kB) Requirement already satisfied: pyyaml>=5.1 in k:\comfyui\comfyui_ex\python_miniconda_env\comfyui\lib\site-packages (from fvcore->pytorch3d==0.7.5) (6.0.1) Requirement already satisfied: tqdm in k:\comfyui\comfyui_ex\python_miniconda_env\comfyui\lib\site-packages (from fvcore->pytorch3d==0.7.5) (4.66.1) Collecting termcolor>=1.1 (from fvcore->pytorch3d==0.7.5) Using cached termcolor-2.4.0-py3-none-any.whl.metadata (6.1 kB) Requirement already satisfied: Pillow in k:\comfyui\comfyui_ex\python_miniconda_env\comfyui\lib\site-packages (from fvcore->pytorch3d==0.7.5) (10.2.0) Collecting tabulate (from fvcore->pytorch3d==0.7.5) Using cached tabulate-0.9.0-py3-none-any.whl (35 kB) Requirement already satisfied: typing-extensions in k:\comfyui\comfyui_ex\python_miniconda_env\comfyui\lib\site-packages (from iopath->pytorch3d==0.7.5) (4.8.0) Collecting portalocker (from iopath->pytorch3d==0.7.5) Using cached portalocker-2.8.2-py3-none-any.whl.metadata (8.5 kB) Collecting pywin32>=226 (from portalocker->iopath->pytorch3d==0.7.5) Using cached pywin32-306-cp311-cp311-win_amd64.whl (9.2 MB) Requirement already satisfied: colorama in k:\comfyui\comfyui_ex\python_miniconda_env\comfyui\lib\site-packages (from tqdm->fvcore->pytorch3d==0.7.5) (0.4.6) Using cached termcolor-2.4.0-py3-none-any.whl (7.7 kB) Using cached portalocker-2.8.2-py3-none-any.whl (17 kB) Building wheels for collected packages: pytorch3d Building wheel for pytorch3d (setup.py) ... error error: subprocess-exited-with-error

Here are screenshot of the error att beginning and end is too long and cant copy here ::

[MrForExample]

thanks for the effort friend, I'll try to make install steps as painless as possible next

I found a way to install pre-build binaries if you point me were to install it I do the process

I think it doesn't matter where you install the pytorch3d, since the command I used is just pip install git+https://github.com/facebookresearch/pytorch3d.git@stable inside my miniconda env

Here are screenshot of the error at beginning and end is too long and cant copy here :

I see, when install from zero, it seems you fail to build without ninja. And error in pip install -r requirement.txt prevent you from install the rest of package.

I updated the install.bat, please give a try again.

[kakachiex2]

Ok thanks MrForExample

[kakachiex2]

New error ::

[kakachiex2]

The first error Warning gone I added the folder to system path but the second error the red one still there

[indianaorz]

I had the same issue when I tried to get this running. Was able to figure it out:

First issue was I was using CUDA 11.8, had to install 12.1.

Then I manually did all the following:

Go to your Your ComfyUI root directory, for my example:

cd C:\Users\reall\Softwares\ComfyUI_windows_portable

conda create -p ./python_miniconda_env/ComfyUI python=3.11

conda will tell what command to use to activate the env

conda activate C:\Users\reall\Softwares\ComfyUI_windows_portable\python_miniconda_env\ComfyUI

This package also works with cu118

pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121

pip install -r ./ComfyUI/requirements.txt

Then go to ComfyUI-3D-Pack directory under the ComfyUI Root Directory\ComfyUI\custom_nodes for my example is:

cd C:\Users\reall\Softwares\ComfyUI_windows_portable\ComfyUI\custom_nodes\ComfyUI-3D-Pack

First make sure the Conda env: python_miniconda_env\ComfyUI is activated, then go to ComfyUI Root Directory\ComfyUI\custom_nodes\ComfyUI-3D-Pack and:

pip install -r requirements.txt

git clone --recursive https://github.com/ashawkey/diff-gaussian-rasterization pip install ./diff-gaussian-rasterization

pip install ./simple-knn

pip install -U xformers --index-url https://download.pytorch.org/whl/cu121

git clone --recursive https://github.com/NVlabs/nvdiffrast/` pip install ./nvdiffrast

Install pointnet2_ops

cd tgs/models/snowflake/pointnet2_ops_lib && python setup.py install && cd ../../../../

Install pytorch_scatter

pip install git+https://github.com/rusty1s/pytorch_scatter.git

Install pytorch3d

pip install git+https://github.com/facebookresearch/pytorch3d.git@stable

Install kiuikit (Computer Vision Library)

pip install git+https://github.com/ashawkey/kiuikit.git

Then there was still a couple packages I was missing when i tried to run it. With the miniconda env still active i ran:

pip install --upgrade scipy

pip install matplotlib

pip install scikit-learn

then i was able to go back to the ComfyUI_windows_portable\ComfyUI dir and run:

python main.py --windows-standalone-build

and use the workflows.

[kakachiex2]

Everything install without any problem the install miniconda.bat work well the only error in the part wen building pytorch wheel

[MrForExample]

Seems you can build all the other cuda packages but not pytorch3d, which means your VS build tools is setup correctly, I'm not really sure what happened in your env, sorry about that, you should check [pytorch3d INSTALL.md] (https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md)

Hi friend, thanks for the effort, I updated the install methods yesterday, so now is pretty much the same for type all the pip command yourself and simply pip those two requirement.txt files. cheers :)

[kakachiex2]

Thanks it works know

[Yunowhoit]

I had the same issue but managed to fix the issue by:

• Manually installing Conda.
• Redirecting the batch file " install_miniconda.bat" found in "ComfyUI\custom_nodes\ComfyUI-3D-Pack"
• Editing line - "python_miniconda_exec= " to the python.py file found in "\python_embeded\Lib\site-packages\torch_dispatch\python.py" (still gave me an error).
• opened comfyUI and it reinstalled the following: - torch-2.2.1-cp311-cp311-win_amd64.whl

This probably isn't the correct fix but seemed to work somehow. I wanted to post this here, just in case it helps other people.

[dcollaoa]

python main.py --windows-standalone-build

I have a problem here, when I build.

I don't know why, I expended like 8 hours solving this... trying a lot of things X_x
