ComfyUI-3D-Pack fails to load in ComfyUI on Linux system

[drwootton]

I tried installing these custom nodes in my Linux ComfyUI installation and the install fails because it cannot find the diff_gaussian_rasterization module. I can't find what module I need to install (pip install ...) so can't complete the install.
Can you tell me what the correct pip install command is?

Also, I had a previous failure where it could not find the kiui module, which I did resolve by running pip install kiui

The requirements.txt file probably needs to be updated to call out the right modules as well.

@drwootton this issue is duplicate - #29

[YanWenKun]

I opened a PR #126

Or you can just install them from:

@YanWenKun Thank you for fixing this. I had to rebuild my virtual environment since I was running with python 3.10, now I have it running on python 3.11. I ran a git cherry-pick of your commit to add your changes on top of my current ComfyUI. I still get the missing diff_gaussian_rasterization error so I'm probably missing a step. I can't rebuild with docker since I'm apparently missing some GPU driver that is needed. So I'll wait until this gets merged into the main repo and try again.

@drwootton hope running this command within container would help:

( this will force-reinstall diff_gaussian_rasterization):

python3 -m pip install --force-reinstall \

Also I have these packages included in my Docker image. Hope it works for you!

[drwootton]

That was the missing step. I ran that in my virtual environment for ComfyUI and it solved the missing diff_gaussian_rasterization error. Loading then failed because I didn't have xformers installed. I don't know if that's my setup error or if there's a missing requirement in the extension's requirements.txt. pip install xformers in my virtual environment. fixed that.
So the workflow for this loads now and runs to completion.
Thanks

@YanWenKun
this wheel file gives me error. Do you know maybe the reasons behind it?

    from diff_gaussian_rasterization import (
  File "path/to/myenv/lib/python3.11/site-packages/diff_gaussian_rasterization/__init__.py", line 15, in <module>
    from . import _C
ImportError: path/to/myenv/lib/python3.11/site-packages/diff_gaussian_rasterization/_C.cpython-311-x86_64-linux-gnu.so: undefined symbol: _ZN3c106detail23torchInternalAssertFailEPKcS2_jS2_RKSs

[YanWenKun]

@ksenia-portu I guess it could be Torch-related, try upgrading it:

python3 -m pip install --upgrade \
        xformers torchvision torchaudio \
        --index-url https://download.pytorch.org/whl/cu121 \
        --extra-index-url https://pypi.org/simple

[ksenia-portu]

@YanWenKun nope it still gives error:

@ksenia-portu Try install from another compiled wheel:

python3 -m pip install --force-reinstall \
  https://github.com/remsky/ComfyUI3D-Assorted-Wheels/raw/main/diff_gaussian_rasterization-0.0.0-cp311-cp311-linux_x86_64.whl

@ksenia-portu

After the installation of the ComfyUI extensions(ComfyUI-Impact-Pack, KJNodes and VHS), you need to install two new wheels that are built, kiui-0.2.7-py3-none-any.whl and torchmcubes-0.1.0-cp311-cp311-linux_x86_64.whl; which should be populated in your ComfyUI-3D-Pack/_Pre_Builds/_Wheels_linux_py311_cu121/.

YanWenKun's solution with either force reinstalling diff_gaussian_rasterization or just force reinstalling all of the wheel files either through the pre-built wheels or his assorted wheels repo should work nine out of ten times. You also need to make sure you're using python 3.11.8/9 or else the dependencies clash or fail(in my experience). I've only been able to get a Docker container to run on Linux Mint 21.3 (an Ubuntu 22.04 derivative).

If you have the hard drive space and still aren't up and running:

I have a slightly tweaked Dockerfile as well as a Docker image if you'd like to try it out here. I'd recommend running the shell script as well; it includes everything you need for both the pre-requisite OpenGL libraries as well as the necessary Nvidia/docker libraries so you don't run into "CUDA device not detected/Pytorch unavailable" errors while building the image.

These solutions are not working.

By the way, I have these packages pre-installed in the Docker image:

Hope that saves some time for Linux users
