ImportError: cannot import name 'check_download_model' from 'utils'

Hi! Thanks for the great work as always. I updated ComfyUI and got the following error: When I commented out all 'check_download_model', the error did not occur.

Traceback (most recent call last):

Pretty much the same error message over here:

build_backbone.py ->
change from utils import check_download_model to

import sys
import os
import importlib.util
path = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
utils_path = os.path.join(path, "utils.py")
spec = importlib.util.spec_from_file_location("utils", utils_path)
utils = importlib.util.module_from_spec(spec)
spec.loader.exec_module(utils)
check_download_model = utils.check_download_model

BiRefNet_node.py -> change from utils import check_download_model to from .utils import check_download_model

work for me :)

or you can try to rename \ComfyUI\custom_nodes\ComfyUI-BiRefNet\utils.py to something unique -> for example brn_utils.py and then use from brn_utils import check_download_model - may helps too
