I spent two days trying to train a LoRa customization on top of Flux 1 dev on Windows with my RTX 4090 but can’t make it work and I don’t know how deep into this topic and python library I need to study. Are there scripts kiddies in this game or only experts ?
I was able to run this script to train a Lora myself without spending any time learning the underlying python libraries.
So you probably better off using Ai-ToolKit https://github.com/ostris/ai-toolkit

Windows is mostly the issue, to really take advantage, you will need linux.
The main thing is having 1. Good images with adequate captions and 2. Knowing what settings to use.
Number 2 is much harder because there’s a lot of bad information out there and the people who train a ton of Loras aren’t usually keen to share. Still, the various programs usually have some defaults that should be acceptable.
