ComfyUI DWPose / SAM2 "model not found" despite downloading — the nested-path fix

Also seen as: "DWPose model not found ComfyUI", "SAM2 model not found", "dw-ll_ucoco_384.onnx missing", "sam2 safetensors not loading"

Direct answer

How do I fix "DWPose / SAM2 preprocessor models not found"?

DWPose and SAM2 preprocessor nodes fail to find their models even though you downloaded them, because these nodes read from nested, node-specific folders that the generic models/ tree is not scanned for — and SAM2 also needs a specific re-serialized format, not Meta’s raw checkpoint.

Key facts

  • iDWPose reads its ONNX files from inside the custom node (custom_nodes/comfyui_controlnet_aux/ckpts/yzd-v/DWPose), not the generic models tree.
  • iSAM2 weights placed in models/sams/ (that is SAM v1) instead of models/sam2/.
  • iYou used Meta’s raw SAM2 .pt — ComfyUI wants the Kijai re-serialized safetensors, whose checkpoint keys differ.

Next step

  1. 1Put the DWPose ONNX files (dw-ll_ucoco_384.onnx + yolox_l.onnx) in custom_nodes/comfyui_controlnet_aux/ckpts/yzd-v/DWPose.
  2. 2Put the SAM2 safetensors from the Kijai/sam2-safetensors mirror in models/sam2/ (not models/sams/).
  3. 3Use the Kijai re-serialized SAM2 safetensors, not Meta’s raw .pt — the keys will not load otherwise.
  4. 4Restart ComfyUI so the nodes re-scan their folders.

If that didn't fix it

  • "Downloaded" is not enough for these nodes — the generic models/ folder is not where they look; the nested node-specific path is.
