Kornia package not found (but it's there!)

[DonKrapf]

OS: Debian 13 (Trixie)
nVidia RTX 5060 Ti (16GB)
Driver Version: 595.58.03
CUDA Version: 13.2
PyTorch: Stable (2.12.0)

Today, May 16 2026, I created a new installation of ComfyUI and ComfyUI-Manager in a virtual environment created with "python3 -m venv comfy3d". Then I used ComfyUI Manager to install TRELLIS2 which also installed GeometryPack. I restarted Comfyui. Log output is below.

I connected with my web browser, and selected "Remove Background" from the ComfyUI-TRELLIS2 templates. I clicked "Run". After a few seconds, the "TRELLIS2 Remove Background" node turned magenta. The log output is below.

The startup log indicates "Found comfy_kitchen backend..."
The error log indicates "Error: No module named 'comfy_kitchen'"

The error log indicates the fatal error "This modeling file requires the following packages that were not found in your environment: kornia. Run pip install kornia"

Running "pip install kornia" within the venv environment yields:
Requirement already satisfied: kornia in ./lib/python3.13/site-packages (0.8.2)
Full output below.

Why is the "Remove Background" node unable to find "comfy_kitchen" and "kornia"? Is this something to do with "comfy-env"? How do I fix this?

Thanks for your help.

Don

@DonKrapf Hi! :) I think I know what the problem was due to (kornia not being installed in the isolated comfy-env).

For context, my nodes install an independent environment so as not to break your existing one.

Please try installing the latest version of TRELLIS2 ("0.2.18") from the ComfyUI-Manager and let me know how it goes! I believe it will solve your problem, but if it doesn't, ping me, I'm always here to help ;)

[DonKrapf]

Updating TRELLIS2 with the ComfyUI-Manager fixed the kornia problem. Thanks!

I guessed at the syntax for nodes/comfy-env.toml and added comfy_kitchen = "*" directly after kornia = "*" but I still get the following error:

[worker:ComfyUI-TRELLIS2] ERROR: Failed to import comfy_kitchen, Error: No module named 'comfy_kitchen', fp8 and fp4 support will not be available.
[worker:ComfyUI-TRELLIS2] WARNING: No comfy kitchen, using old apply_rope functions.

Oddly, during start-up, Comfyui reports it as comfy-kitchen, instead of comfy_kitchen, so I tried that too but with the same results.

It looks like I guessed wrong. How do I get the comfy_kitchen into the environment so the worker can find it?

[cooperdk]

I have this issue too - TWO MONTHS LATER. Everything is up to date!
