Coming to the latest problem, I do not manage to create any Flux dreambooth with your Kohya installation on my PC, unfortunately. I was already successful with Kohya Flux Lora trainings, also with OT Finetuning SDXL trainings, all loca trainings on my PC, but now there seem to be a problem (crash) at the moment Kohya wants to save the first safesensors file. I am running the training on a RTX4080 super with 16GB VRAM (could not afford more, unfortunately), choose your 16GB config (which leads to a VRAM usage of about 14,4 GB, shared usage of 18,3/31.5). Speed is approximately 5s/it, which is ok, I think. I tried with different number of steps (200, 100 ….down to much less), had started with 124 pics (1 repeat), am now down to 15 to for testing purpose. Everything goes fine until Kohya tries to save the first intermediate epoch/safetensor file. Then it crashes, terminates the training, as if it could not save the file. I tried to have it saved at many different places, it makes no difference. Could it be that the size is too big? As already mentioned, I had no problem with the Kohya Flux Loras and OT SDXL Finetunings.
