Installation

Automatic Install (Recommended)

ComfyUI Manager

As of version 0.1.0, this extension is meant to be installed with the ComfyUI-Manager, which helps a lot with handling the various install issues faced by various environments.

Virtual Env

There is also an experimental one liner install using the following command from ComfyUI's root. It will download the code, install the dependencies and run the install script:

curl -sSL "https://raw.githubusercontent.com/username/repo/main/install.py" | python3 -

Models Download

Some nodes require extra models to be downloaded, you can interactively do it using the same python environment as above:

python scripts/download_models.py

then follow the prompt or just press enter to download every models.

Note You can use the following to download all models without prompt:

python scripts/download_models.py -y

Web Extensions

On first run the script tries to symlink the web extensions to your comfy web/extensions folder. In case it fails you can manually copy the mtb folder to ComfyUI/web/extensions it only provides a color widget for now shared by a few nodes:

color widget preview

Old installation method (MANUAL)

Dependencies

Custom Virtualenv (I use this mainly)
  1. Make sure you are in the Python environment you use for ComfyUI.
  2. Install the required dependencies by running the following command:
pip install -r comfy_mtb/reqs.txt

Comfy-portable / standalone (from ComfyUI releases)

If you use the python-embeded from ComfyUI standalone then you are not able to pip install dependencies with binaries when they don't have wheels, in this case check the last release there is a bundle for linux and windows with prebuilt wheels (only the ones that require building from source), check this issue (#1) for more info. image

Google Colab

Add a new code cell just after the Run ComfyUI with localtunnel (Recommended Way) header (before the code cell) preview of where to add it on colab

# download the nodes
!git clone --recursive https://github.com/melMass/comfy_mtb.git custom_nodes/comfy_mtb

# download all models
!python custom_nodes/comfy_mtb/scripts/download_models.py -y

# install the dependencies
!pip install -r custom_nodes/comfy_mtb/reqs.txt -f https://download.openmmlab.com/mmcv/dist/cu118/torch2.0/index.html

If after running this, colab complains about needing to restart runtime, do it, and then do not rerun earlier cells, just the one to run the localtunnel. (you might have to add a cell with %cd ComfyUI first...)

Note: If you don't need all models, remove the -y as collab actually supports user input: image
