ComfyUI Node: Lora Loader

Lora Loader:

The AV_LoraLoader node is designed to facilitate the loading of LoRA (Low-Rank Adaptation) models into your AI art generation workflow. This node allows you to override the default LoRA model with a specified one and enables or disables the loading process based on your requirements. By providing flexibility in model selection and control over the loading process, AV_LoraLoader ensures that you can fine-tune your AI models with ease, enhancing the creative possibilities and performance of your art generation tasks.

Lora Loader Input Parameters:

model

This parameter represents the base model that you want to enhance with the LoRA model. It is a required input and should be a valid AI model that supports LoRA integration.

clip

This parameter represents the CLIP (Contrastive Language-Image Pre-Training) model that works alongside the base model. It is a required input and should be a valid CLIP model.

lora_name

This parameter specifies the name of the LoRA model to be loaded. It is a required input and should match one of the available LoRA models in your system.

lora_override

This optional parameter allows you to override the default LoRA model specified in lora_name. If set to a valid LoRA model name, it will replace the default model. The default value is "None".

enabled

This optional parameter controls whether the LoRA model loading process is enabled or disabled. If set to True, the LoRA model will be loaded; if set to False, the loading process will be skipped. The default value is True.

Lora Loader Output Parameters:

MODEL

This output represents the base model enhanced with the loaded LoRA model. If the loading process is disabled, it will return the original base model.

CLIP

This output represents the CLIP model that works alongside the enhanced base model. If the loading process is disabled, it will return the original CLIP model.

Lora Loader Usage Tips:

• To quickly switch between different LoRA models, use the lora_override parameter to specify the desired model without changing the default lora_name.
• If you want to temporarily disable the LoRA model loading, set the enabled parameter to False without removing the node from your workflow.

Lora Loader Common Errors and Solutions:

Warning: Not found Lora model <lora_override>. Use <lora_name> instead.

• Explanation: This warning indicates that the specified lora_override model was not found in the system, and the default lora_name model will be used instead.
• Solution: Ensure that the lora_override parameter is set to a valid LoRA model name available in your system. Check the list of available models and correct any typos in the model name.

Error: Invalid model or clip input.

• Explanation: This error occurs when the model or clip input parameters are not valid AI models that support LoRA integration.
• Solution: Verify that the model and clip parameters are set to valid AI models. Ensure that these models are compatible with LoRA and are correctly loaded into your workflow.
