Welcome to SD XL
I've embarked on a mission to investigate and test as well to collaborate on this.
01101011 01100001 01100110 01101011 01100001
In order to achieve this, I used comfyUI and Bmaltis GUI for Kohya/SDXL branch. So Kohya will do the Lora training, comfy will do the testing and generation.
ComfyUI requires you to use a UI file, it needs one extension as well so please check out my GUIs file and use the recommended extension. Once you get these installed you can now generate images, generate images with face detailer and compare & combine lora.
ComfyUI extensions must all be placed in the custom_nodes location. They will show like this if they install correctly. If you see [Load_Failed], the error will be up above. Usually it means you need to run a python command in the way explained in the readme of the extension.
I recommend you find UI's built by others to start but if you want to start tinkering yourself make sure you take node of the "examples" that are often inside the githubs like this this.
Results so far
I've been using the bmaltis lokr preset. It seems to just work out of the box. I've successfully trained lora using my exact dataset as 1.5. I've also made new 1024x1024 datasets. I've had success with WD1.4 style tags as well as blip tags.
