how to use, say, "reference only" now, that "None" model is gone via api?

[dermesut]

title says it basically.
we had {"model_list": ["None", ...]} in http://127.0.0.1:7861/controlnet/model_list', but now "None" is gone.
it was convenient to have "None" in the model_list, since i could offer that in a drop-down of my app, if the user decided to go with a preprocessor like "reference_only". now i am basically forced to have "reference_only" combined with any of the entries in the model_list.
a solution could of course be, to code s.th. that recognizes the preprocessor selection, thus ignores what is set in the drop-down for the models. or s.th. similar.
but i wonder, why "None" had to be taken away, but even more so, if we could please get it back.

I don't think the API ever returns "None" in model list unless you are using a very old version of ControlNet. See model names impl here:

sd-webui-controlnet/scripts/global_state.py

Lines 65 to 89 in 471f564

	def update_cn_models():
	cn_models.clear()
	ext_dirs = (shared.opts.data.get("control_net_models_path", None), getattr(shared.cmd_opts, 'controlnet_dir', None))
	extra_lora_paths = (extra_lora_path for extra_lora_path in ext_dirs
	if extra_lora_path is not None and os.path.exists(extra_lora_path))
	paths = [cn_models_dir, cn_models_dir_old, *extra_lora_paths]
	for path in paths:
	sort_by = shared.opts.data.get(
	"control_net_models_sort_models_by", "name")
	filter_by = shared.opts.data.get("control_net_models_name_filter", "")
	found = get_all_models(sort_by, filter_by, path)
	cn_models.update({**found, **cn_models})
	# insert "None" at the beginning of `cn_models` in-place
	cn_models_copy = OrderedDict(cn_models)
	cn_models.clear()
	cn_models.update({**{"None": None}, **cn_models_copy})
	cn_models_names.clear()
	for name_and_hash, filename in cn_models.items():
	if filename is None:
	continue
	name = os.path.splitext(os.path.basename(filename))[0].lower()
	cn_models_names[name] = name_and_hash

In line 86, the None entry is filtered out from the name list. The function has not been touched for over a year now.

Please reopen if you can find a PR/commit that changes this behaviour recently.

oh ok, thx. i can see that.
weird though, since i am not aware that i could have been using a very old version of controlnet.
i keep updating the controlnet extension as soon as i see a new version being indicated in the extensions-check in a1111.
i do that in all versions of a1111 that i have installed: 1.7.0, 1.8.0, 1.9.0 (which became 1.9.3 in the last days to hours).
and the version-indications in the controlnet units showed the correct updated version number.
since i have updated controlnet in all of the installations, i can not tell which commit hash was the last one that had "None" in the model_list, but it still was in 1.1.445. only the last one or two iteration of 1.1.445 "lost" the "None".
also, i do not "add anything" in my code... i just fetch the list via the given adress and list it in my app.
sorry, i have no idea, how this could be happening atm.

Can you find a good version where "None" is included in the model_list?

[dermesut]

i am sorry, that i am not experienced with how github/versioning etc. really works.
i just keep updating the version that is being offered in the check in a1111.
i can just tell, that i was using 1.1.445 (at least the first "iterations") with "None" included. and - of course - every version before that.
now, which commit that was, how to get that commit hash or a slightly older one.... and then install that one to test it... i have no idea.
i am very sorry. unless you can give me a quick tip on how to do that, i certainly don't want to steal your time with such novice stuff.

[dermesut]

so, i have been familiarizing myself a bit now.
i have tried diverse commits going back to 1.1.433, weeks old. git-cloning them always led to the same conclusion: there is no "None" being returned.
i also tried the same thing via the backup restore feature of a1111, again going back weeks.
same result. it's as though it never happened.
yet, yesterday i played around with "reference only" for a bit - i remember that well, because i rarely use that preprocessor - comfortably having a "None-model"..
this is very confusing to me - since every extension-update has been showing the evolving version number, giving me no reason to believe that i might actually have (very?) old stuff running, or at least bits of it.

well, now that i am in the same situation as the rest of the world apparently has been in for the past decade or two - having "None" not being returned - i'll figure out a way to live with that.

i am very sorry for wasting your time with such nonsense. thank you for your patience.
please close this, i'll mark your reply above as the answer.
