Error message when running Lora Training in ComfyUI

[victorhe2002]

I am trying to train my own model, and I have the images and tags ready.
In the StableSwarm, I installed the ComfyUI manager and installed the custom nodes "Lora Training in ComfyUI".
But when I try to run it, here is the warning message "[Warning] ComfyUI-0 on port 7821 stderr: Traceback (most recent call last):" Could anyone please help me to see what I was missing or went wrong?

Thank you!
