Error when Installing on latest ComfyUI

[brokenheist]

I'm trying to install on the latest ComfyUI, does this means is only available for Python 3.11?

Using Python 3.12.8 environment at: /ComfyUI/.venv
Resolved 78 packages in 2.29s
x Failed to build numpy==1.23.5
|-> The build backend returned an error
-> Call to setuptools.build_meta:legacy.build_wheel` failed (exit status: 1)

  [stderr]
  Traceback (most recent call last):
    File "<string>", line 8, in <module>

  ModuleNotFoundError: No module named 'distutils'

  hint: `distutils` was removed from the standard library in Python 3.12. Consider adding a constraint (like `numpy >1.23.5`) to avoid building a version of `numpy` that depends on
  `distutils`.

help: numpy (v1.23.5) was included because python-coreml-stable-diffusion (v1.1.0) depends on numpy

Try installing numpy version 1.26.4? I was having numpy issues with pytorch 2.8.0 nightly and python 3.10 until I got numpy updated to specifically this version.

But yeah distutils in numpy was removed with python 3.12.. https://numpy.org/devdocs/reference/distutils_status_migration.html

The problem is the dependency on Apple's Stable Diffusion library which is still using distutils and doesn't seem to work even if setuptools are installed. https://github.com/apple/ml-stable-diffusion

I am experiencing this very numpy version issue with Apple's SD library, as well. I'm still a novice to ML on the whole and my biggest fear is getting caught in config/dependency purgatory, so I'm looking around for confirmed workarounds before attempting a blank slate.

That said, has reverting to numpy 1.26.4 allowed for a clean swap with these nodes in anyone's existing workflows?

To downgrade ComfyUI's python version, I replaced the .venv in the installation folder with this command:
/Applications/ComfyUI.app/Contents/Resources/uv/macos/uv "venv" "--python" "3.11.9" "--python-preference" "only-managed"
Next launch ComfyUI will ask to install dependencies again, and then you'll be able to fix the install of the CoreML nodes in the manager ✌️
