ComfyUI Node: PM Save LoRA

PM Save LoRA:

The PM LoRA Save node is designed to save a LoRA (Low-Rank Adaptation) model to a specified file. This node is particularly useful for AI artists who work with custom-trained models and need to save their work in a structured and efficient manner. The node allows you to adjust the strength of the model and clip components before saving, ensuring that the saved model meets your specific requirements. By providing a straightforward interface for saving LoRA models, this node helps streamline the workflow and ensures that your models are stored safely and correctly.

PM Save LoRA Input Parameters:

lora

This parameter expects a LoRA model object. The LoRA model contains the weights and configurations that define the model's behavior. The strength of the model and clip components can be adjusted before saving, which allows for fine-tuning the saved model to better suit your needs.

file_name

This parameter is a string that specifies the name of the file where the LoRA model will be saved. It does not support multiline input and defaults to "merged". The file name is crucial for identifying and organizing your saved models.

extension

This parameter specifies the file extension for the saved LoRA model. Currently, it supports the "safetensors" extension. The file extension determines the format in which the model will be saved, ensuring compatibility with other tools and workflows.

PM Save LoRA Output Parameters:

This node does not produce any output parameters. Its primary function is to save the LoRA model to a specified file.

PM Save LoRA Usage Tips:

• Ensure that the file_name parameter is unique and descriptive to avoid overwriting existing models and to make it easier to identify the saved model later.
• Adjust the strength_model and strength_clip parameters within the LoRA model to fine-tune the saved model's performance according to your specific needs.
• Use the "safetensors" extension to ensure that the saved model is in a compatible and efficient format.

PM Save LoRA Common Errors and Solutions:

"Saving LoRA to <path> failed"

• Explanation: This error occurs when the node fails to save the LoRA model to the specified path.
• Solution: Ensure that the specified path is correct and that you have write permissions to the directory. Check for any typos in the file_name and extension parameters.

"Invalid LoRA model"

• Explanation: This error occurs when the provided LoRA model is not valid or is missing required components.
• Solution: Verify that the LoRA model object is correctly formatted and contains all necessary components. Ensure that the model has been properly loaded and configured before attempting to save.

"Unsupported file extension"

• Explanation: This error occurs when an unsupported file extension is provided.
• Solution: Use the "safetensors" extension, as it is the supported format for saving LoRA models with this node.
