I have a new laptop with the rtx 5090. I've been trying different options to train a Lora including using nodes on ComfyUI, installing AI Toolkit, Fluxgym, they have all been a headache either giving me error after error when trying to install or when I do get it running, nothing happens. For example, I managed to get Fluxgym running, but when I train it says training is complete but the safetensors file is not in the Outputs file at all. Is there just an easier way to train locally? Thanks!
