Documentation

• Class name: ConditioningConcat
• Category: conditioning
• Output node: False
• Repo Ref: https://github.com/comfyanonymous/ComfyUI

ConditioningConcat节点旨在将两个条件输入合并为单个输出。它巧妙地将源条件输入与目标条件输入沿指定维度连接起来，确保生成的输出非常适合神经网络架构中的后续处理步骤。

Input types

Required

• conditioning_to
  • 'conditioning_to'参数表示将与另一个条件输入连接的目标条件输入。它在确定最终输出的结构中起着关键作用，因为它决定了附加额外条件信息的基础。
  • Comfy dtype: CONDITIONING
  • Python dtype: List[Tuple[torch.Tensor, Any]]
• conditioning_from
  • 'conditioning_from'参数提供了将与'conditioning_to'结合的源条件输入。它很重要，因为它为最终连接的输出贡献了额外的上下文或特征，可能增强模型做出明智预测的能力。
  • Comfy dtype: CONDITIONING
  • Python dtype: List[Tuple[torch.Tensor, Any]]

Output types

• output
  • ConditioningConcat节点的输出是合并后的条件张量，整合了'conditioning_to'和'conditioning_from'输入的元素。这个输出被策略性地构建，以与下游神经网络操作兼容。
  • Comfy dtype: CONDITIONING
  • Python dtype: List[Tuple[torch.Tensor, Any]]

Usage tips

• Infra type: CPU
