SAMLoader (Impact)

ImpactPack

SAMLoader

Load the SAM (Segment Anything) model. This can be used in places that utilize SAM detection functionality, such as SAMDetector or SimpleDetector. The SAM detection functionality in Impact Pack must use the SAM_MODEL loaded through this node.

Example

JSON Example

{
  "class_type": "SAMLoader",
  "inputs": {
    "model_name": "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors",
    "device_mode": "AUTO"
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
model_name?	ENUM 1 options sam_vit_b_01ec64.pth URL: Model	required	-	-
device_mode?	ENUM 3 options AUTO Prefer GPU CPU	required	-	-

Outputs

Index	Name	Type	Is List	Connection Reference
0	SAM_MODEL	SAM_MODEL	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this SAMLoader node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• SAM_MODEL (SAM_MODEL): ["5", 0]
