The section never held nodes -- every entry is a whole pack repo. Read literally, `[node_reqs]` says "the requirements of my node", which is pip packages, and that section genuinely exists one file over as [dependencies] in comfy-env.toml. `[node_packs]` names the unit and sits parallel to the existing [cuda_packages]. Requires comfy-env >= 0.4.27, which renames the key with no shim: the root file has a closed schema, so an old comfy-env rejects [node_packs] by name and a new one rejects [node_reqs] by name. Neither fails silently.

Installation
Three options, in order of speed → reliability:
- ComfyUI Manager (recommended) — search for
SAM3in the Manager and click Install from the highest version displayed. If that doesn't work, try nightly. - Manager via Git URL — in ComfyUI Manager: "Install via Git URL" with
https://github.com/PozzettiAndrea/ComfyUI-SAM3.git. - Manual (most reliable):
cd ComfyUI/custom_nodes git clone https://github.com/PozzettiAndrea/ComfyUI-SAM3.git cd ComfyUI-SAM3 pip install -r requirements.txt --upgrade python install.py
