GetLatentsFromBatchIndexed¶
Documentation¶
- Class name:
GetLatentsFromBatchIndexed
- Category:
KJNodes
- Output node:
False
This node is designed to select and return specific latents from a given batch based on provided indices. It facilitates the extraction of a subset of latents for further processing or analysis, making it a crucial component for operations requiring targeted manipulation or inspection of latent spaces.
Input types¶
Required¶
latents
- The 'latents' parameter represents the batch of latents from which specific items will be selected. It is crucial for determining the scope of latents available for selection.
- Comfy dtype:
LATENT
- Python dtype:
Dict[str, torch.Tensor]
indexes
- The 'indexes' parameter specifies the indices of the latents to be selected from the batch. It plays a key role in identifying which latents are to be extracted and processed.
- Comfy dtype:
STRING
- Python dtype:
str
Output types¶
latent
- Comfy dtype:
LATENT
- The output is a modified version of the input latent batch, containing only the latents at the specified indices.
- Python dtype:
Tuple[Dict[str, torch.Tensor]]
- Comfy dtype:
Usage tips¶
- Infra type:
GPU
- Common nodes: unknown
