"""
This should be imported before entrypoints to correctly configure global options prior to importing packages like torch and cv2.

Use this instead of cli_args to import the args:

>>> from comfy.cmd.main_pre import args

It will enable command line argument parsing. If this isn't desired, you must author your own implementation of these fixes.
