What happened

All of a sudden some LoRa's just stopped being able to be installed.

[2024-10-16 15:47:52,892]::[ModelInstallService]::ERROR --> Model install error: Z:/AI-Models/Art-Models/Loras/Flux.1 D/Style-SFW/style/EnvyFluxDarkToon01.safetensors
InvalidModelConfigException: Unable to determine model type for Z:\AI-Models\Art-Models\Loras\Flux.1 D\Style-SFW\style\EnvyFluxDarkToon01.safetensors

Given that Envy's LoRa were working, and then they stopped I reached out to Envy and asked if they changed something recently. They mentioned that they started making DoRa's in "OneTrainer" Just to be clear the non-flux "LoRas" and "DoRa" from the creator work just fine in Invoke, but the Flux version does not. Again it's only something recent, and not the older ones. (Older by literally 2 weeks), any LoRa they had created after Oct 1st for FLUX appears to have this issue.

They have informed me that they have done nothing different. Just that they started creating DoRa's in OneTrainer.

List of FLUX LoRas that are having the issue -
-EnvyFluxDarkWatercolor01.safetensors
-EnvyFluxMoonlightFusion01.safetensors
-EnvyFluxThickOilPainting01a.safetensors
-EnvyFluxSakuraSunset01.safetensors
-EnvyFlux3Cute5U01b.safetensors
-EnvyFluxDarkToon01.safetensors
-EnvyFluxThickOilPainting01c.safetensors

-EnvyFluxAnimeSketch01.safetensors
-EnvyFluxDreamtown01.safetensors
-EnvyFluxThickOilPainting01d.safetensors
-EnvyFlux3Cute5U01a.safetensors

All their other FLUX LoRa's as of today (Oct 16th) work just fine.

What you expected to happen

It should have installed and used the FLUX LoRa

Can you please provide a couple links to the specific versions of the LoRAs that don't work?

Can you please provide a couple links to the specific versions of the LoRAs that don't work?

Certainly! I'll give you three of the non-loading ones and three of the loading and working ones.

Thanks!

Here is another one that doesn't install currently:

OK So Envy got a pinch more info for me. They said "Those are DoRa's but I must have labeled them LoRa's out of habbit..." So maybe because it's labeled a LoRa, but is really coded as a DoRa Invoke is having a problem understanding?
I only say that because other DoRa's for non-flux models load just fine in Invoke. But those are specifically tagged as DoRa. Maybe? I am not a coder by any means, just trying to follow some logic here.

Thanks for the insight but what is a Dora? And how can we check what they are labeled, and relabel them if necessary?

From what I've read, DoRA is a faster model than LoRA.
How can you know if a DoRA has been tagged a LoRA? I have no idea, the creator needs to make certain to tag the metadata DoRA... Because if they tag it LoRA it appears Invoke doesn't like it. That said, A1111, ComfyUI, and Foooocus don't seem to have this problem. This is distinctively a InvokeAI issue.

If I had to guess, having the file tagged LoRA but is really configured to be a DoRA, Invoke probably has a specific loading protocol to read just LoRA formatting. The other programs might have taken a more 'dumbed down' approach, you feed it a file and it determines what it is based on the file structure. It's slower doing it this way, but more flexible for dummies that mis-tag their file structure :) But I am not a coder so I'm just throwing stuff out there.

As suggested by the admins on the discord channel, I'm reporting here LORA styles for Flux that don't work. The same styles work perfectly well with FLUX in Swartm UI, so everything is fine with them. None of these styles want to install in Invoke.

Here is one exception and a slightly different case. A style that theoretically installs, but then throws an error when you try to use it.

Two more styles that don't work.

Another lora style that Invoke failed to install.

Another on. Please do something.

Another on. Every good model for cyborg stuff don't work in Invoke.
