Wd14 tagger re-runs the same image

[wulfila07]

Why is the tagger re-running even if I keep the same image loaded (already tagged in a previous run)? Is there a way to prevent it?

i think this problem is important,
if resolved, can save lot of time when using workflows, especially the ones have lots of nodes was set after the wd14 tagger.

i did a detailed test, what i have found was:
in the 1st execution, the wd14tagger-node runs (of course),
after the 1st exection, if inputs don't change, in the 2nd execution, the wd14tagger-node re-runs,
after the 2nd exection, if inputs don't change, in the 3rd or later execution, the wd14tagger-node doesn't re-run.

though the wd14tagger-node doesn't re-run every time, but still some problem exists: it shouldn't re-run at the 2nd time, it still wastes user's time.

trying to fix this, i added

   print(f"""Your input contains:
            model:{model}
            threshold:{threshold}
            character_threshold:{character_threshold}
            exclude_tags:{exclude_tags}
            replace_underscore:{replace_underscore}
            trailing_comma:{trailing_comma}
        """)

to line 192 of "custom_nodes\ComfyUI-WD14-Tagger\wd14tagger.py",
then restart comfyui,
in the this node's 1st and the 2nd runs, i got exact same outputs, it means args didn't change in the 2 runs.

maybe its a bug form comyui? don't know, i gave up.

Also did some testing. Defining IS_CHANGED with constant value does not help.
def IS_CHANGED(self, ...): return False

Checked other nodes maintained by this author, ex. pysssss String Function 🐍 with some very basic setup:

Same behaviour.
Disabled import of all other custom_nodes. Behaviour persists.
