LoRA Stack to String converter

Documentation

• Class name: LoRA Stack to String converter
• Category: Efficiency Nodes/Misc
• Output node: False

The LoRA Stack to String converter node is designed to transform a list of LoRA (Low-Rank Adaptation) model configurations, each represented as a tuple, into a single, space-separated string. This conversion facilitates the efficient representation and communication of LoRA model parameters for various applications, including model configuration and debugging.

Input types

Required

• lora_stack
  • Represents a list of tuples, each containing a model identifier and two numerical values, which are to be converted into a formatted string. This input is crucial for generating a compact representation of LoRA model configurations.
  • Comfy dtype: LORA_STACK
  • Python dtype: List[Tuple[str, float, float]]

Output types

• LoRA string
  • Comfy dtype: STRING
  • A single string that concatenates all the input tuples into a formatted, space-separated sequence, enabling easy interpretation and use of LoRA model configurations.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
