Issue on training Flux1 LORA, and Fine-Tuning pretrained model.

[Hibiki82]

My GPU is RTX 4090 and 64GB of system ram running on a Linux server host docker container.

NVIDIA-SMI 560.35.03 Driver Version: 560.35.03 CUDA Version: 12.6

1. I installed git clone -b sd3-flux.1 https://github.com/bmaltais/kohya_ss.git (I tried with multiples branches)
2. mix precision of bf16 and tried to train with t5-xxl fp16 and fp8. (failed)
3. Clip_l fp16
4. for some reason CPU Offload Checkpointing is always on? (cannot turn off?)
5. I was trying with 8500 images at a batch size of 1 and still shows not enough VRAM? I've tried with Adafactor and all the other low VRAM required optimizer.
6. for my dataset around 47 buckets was created. at training resolution of 512x512.

This seems to be CuDNN/CUDA/PyTorch issue: https://github.com/huggingface/diffusers/issues/9704

Hi, when training LoRA and Full fine-tune Flux.1 models, which branch should I be using? And I tired to follow the document on training with 24gb VRAM but I can't get it to work. I can show you the Json and TOML for inspection. The issue of cuDNN is it because of I'm training on my docker container from my own docker image?
