Add support for models extra path

[alexisrolland]

Hi Kijai,
Thank you for creating this node.

ComfyUI allows to provide a custom path to store models in a single location and load them from there:
https://github.com/comfyanonymous/ComfyUI/blob/master/extra_model_paths.yaml.example

I have been using it successfully with other models, but it seems the Florence 2 nodes do not support this feature:

My extra_model_paths.yaml is as follow:

comfyui:
    base_path: D:\alexis\ComfyUI-Models\
    checkpoints: models\checkpoints\
    clip_vision: models\clip_vision\
    controlnet: models\controlnet\
    depthanything: models\depthanything\
    insightface: models\insightface\
    ipadapter: models\ipadapter\
    LLM: models\LLM\
    loras: models\loras\
    upscale_models: models\upscale_models\

ComfyUI-Florence2 returns the error:

FileNotFoundError: [WinError 3] The system cannot find the path specified: 'D:\alexis\ComfyUI-Creative-Upscale\ComfyUI\models\LLM'

It should search the models in the path D:\alexis\ComfyUI-Models\models\LLM\

Cheers!

Yes, would be a nice to use the models from the local Ollama installation.

You can look this PR. Or you can use this repo https://github.com/CPPAlien/ComfyUI-Florence2

I was just about to ask why the models are hardwired i.e., won't work with 'extra_model_paths.yaml' then I found this post.

Any updates on this ?

# Comfy Utils
import folder_paths

comfy_model_dir = os.path.join(folder_paths.models_dir, "LLM")

This seems to be enough to work with LLM in extra_path

(Edit: nevermind it's a bit more complex and the PR #88 works just fine)
