Step-by-step pin wiring for ComfyUI-Manager
- Drop ComfyUI-Manager onto the canvas by double-clicking and searching its title.
- Connect all required upstream wires (`Top menu bar Manager button`) from your checkpoint loader, prompt conditioning, or image preprocessor.
- Route the output (`Install Custom Nodes, Install Missing Nodes, Model Manager`) into your downstream KSampler or VAE Decode node, then click **Queue Prompt**.
Fixing dependency conflicts and type mismatches
If the console prints a Python import error or tensor shape mismatch on this node, verify that your checkpoint family (SD 1.5, SDXL, or Flux) matches any attached LoRA, ControlNet, or IPAdapter weight.
For custom node packs on Windows, run **Update All** inside ComfyUI-Manager or grab a fresh desktop environment from /download.
FAQs
Why won't a wire snap onto ComfyUI-Manager?
ComfyUI enforces strict pin types. Check that the upstream output matches `Top menu bar Manager button` and insert a VAE Encode/Decode or preprocessor node if converting between pixels and latents.
How do I bypass this node temporarily without deleting my wires?
Select the node on the canvas and press **Ctrl+B** (Bypass) or **Ctrl+M** (Mute) to test your graph without disconnecting cables.
