I INSTALL LORA BUT I CAN'T USE IT

[Pfannkuchensack]

Can you Look in the Model Manager if you can find the lora and make a Screenshot of the info about it

It's the same issue I reported on discord (and provided some lora files for testing).
It's not being related to Flux2 klein and this can't be changed.

I have a similar problem with Z-Image loras... it installs without being related to any model, and I can change it, but when generating images, I receive:

[2026-02-01 15:04:30,216]::[LayerPatcher]::WARNING --> Failed to find module for LoRA layer key: lora_transformer-lora_unet_layers_0_attention_out

There are more lines, this is a sample. Both loras (F2.Klein and Z-Image) work on ComfyUI

ZiT LoRAs should be working. If you have a ZiT LoRA that isn't recognized correctly, please post its URL here for testing.

Flux.2 Klein LoRAs are not currently supported. From the release notes:

InvokeAI does not currently support F2K LoRAs or ControlNets... In addition, only the Euler sampler is currently available. Support for LoRAs and additional schedulers will be added in a future release.

This is a zimage tranined with musubi-tuner. Works on comfyUI. I trained for troubleshooting purposes with only 100 steps
