After resolving a number of missing packages am unable to progress past installing pytorch3d

[renwerx]

The AI consensus is that there is no version compatible with pytorch version: 2.9.1+cu128. Not sure where to go from here without downgrading torch which I'm hesitant to do lest it cause knock-on effects.

Relevant section of startup log as follows:

@renwerx yeah, exactly. That’s why 3D-Pack auto-installs torch 2.7.0 — we have prebuilt wheels for it, so everything works out of the box without any headaches.

[renwerx]

All I did was install via manager. Then when that failed I pip install -r requirements.txt. It's great that you have prebuilt wheels but how do I use them? I ended up pip install --no-build-isolation "git+https://github.com/facebookresearch/pytorch3d.git@stable" but even though it said it worked I'm sceptical as now lots of new errors and warnings are thrown on comfy startup. If I need to delete my env and start from scratch I'm happy to do so. By way of context the recent errors were:

[renwerx]

@DenisKochetov Are you suggesting to downgrade to torch 2.7.0 manually then reattempt installation?

[DenisKochetov]

@renwerx Yeah, I recommend using a separate environment for the 3D-Pack.
First, install ComfyUI.
Then install the 3D-Pack like this:

git clone -b dev https://github.com/Comfy-Org/ComfyUI-3D-Pack.git
cd ComfyUI-3D-Pack
pip install -r requirements.txt
python install.py

After that, send me any errors you get here.

[renwerx]

@DenisKochetov Not a great start lol:

@renwerx
git clone -b dev https://github.com/MrForExample/ComfyUI-3D-Pack.git

sorry wrong path

[renwerx]

@DenisKochetov Don't think that worked:

Try reinstalling diffusers

pip install --force-reinstall diffusers==0.31.0 transformers==4.46.2

Restart ComfyUI afterwards.

[renwerx]

@DenisKochetov Thanks for all your help but after doing that (then downgrading numpy due to an incompatibility error) I'm getting what looks to be exactly the same error on startup:

@renwerx strange
and if you run
pip install --force-reinstall diffusers==0.31.0 transformers==4.46.2
after installation what do you get? same error?

[renwerx]

@DenisKochetov At the end of the install I get an incompatibility warning:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

@renwerx
Please try upgrading all 3 libraries to the same versions I’m using.
Your current setup mixes old diffusers with newer transformers/peft, which cannot work together.

Run this in your comfy3D environment:

pip install --force-reinstall peft==0.18.0 diffusers==0.35.2 transformers==4.57.1

After that, restart ComfyUI completely.

This combination is fully compatible and works on my side without the “transformers.modeling_layers” import error.
