ComfyUI Extension: Lora-Training-in-Comfy

Lora-Training-in-Comfy Introduction

Lora-Training-in-Comfy is a custom extension designed to simplify the process of training Low-Rank Adaptation (LoRA) models directly within ComfyUI. This extension is particularly useful for AI artists who want to create and fine-tune their own models without needing extensive technical knowledge. By integrating LoRA training into ComfyUI, the author has made it easier to manage and test your models in a streamlined workflow.

Key Features:

• Ease of Use: Train LoRA models directly within ComfyUI, saving time and reducing complexity.
• Automatic Saving: Models are saved directly in the ComfyUI LoRA folder, making them immediately available for testing.
• Customizable Settings: Adjust various training parameters to suit your specific needs.
• Compatibility: Works with multiple model types, including SD 1.5, SD 2.0, SD Turbo, and LCM.

How Lora-Training-in-Comfy Works

Lora-Training-in-Comfy operates by integrating a custom node into ComfyUI, allowing you to train LoRA models using your own dataset of images and captions. Here’s a simplified breakdown of how it works:

1. Data Preparation: Gather a folder of images with corresponding captions. Rename the folder to follow the format [number]_[description].
2. Path Configuration: Copy the path of the parent directory containing your image folder and paste it into the data_path field in the node settings.
3. Training: Choose a name for your LoRA model and adjust any other settings as needed. Click Queue Prompt to start the training process.
4. Testing: Once training is complete, refresh ComfyUI to see your new model in the LoRA folder, ready for testing.
