Getting 'IndexError: list index out of range' in ComfyUI - Help with LoRA Caption Save Node

Hi all,

I’m using ComfyUI on a Mac Studio (M1 Ultra, 64GB) and running into a "list index out of range" error. I'm connecting the LoRA Caption Load node to the WD14 Tagger, and then to the LoRA Caption Save node. I'm pointing to a folder with both .png images and .txt caption files within my ComfyUI folder.

Am I doing something wrong in this setup, or is there something specific I need to watch out for? Any tips or alternative techniques for creating my own LoRA model?

Thanks in advance!

Why don't you upload screenshots of your workflow? It's a system info image, and it's not possible to fully understand the problem by simply reading the error log.

Sorry about that .I updated screen shots to my Lora Setup for Training . Im still learning all of this , and using Gbt to get a better grasp , It seems like something is up with my Loracaption.py file . I keep hitting this brick wall. Any help is much appreciated!
