requirements.txt

# PromptChain — dependencies for the ComfyUI Registry.
#
# Two groups:
#   1. Core load-time deps PromptChain's own code imports (ComfyUI ships the
#      rest: torch, numpy, Pillow, transformers, einops, av, requests, ...).
#   2. Optional feature deps, declared so they install WITH the pack (Manager /
#      pip at install time) instead of the node running pip at runtime — which
#      the ComfyUI Registry forbids. These cover PuLID, the Face Detailer, and
#      AI Selection. They make a fresh install heavier but keep it compliant.
#
# Torch/numpy/opencv-downgrading pins from the bundled packs (numpy<2,
# ml_dtypes, onnxruntime-gpu, facenet-pytorch) are deliberately NOT mirrored
# here, so `pip install -r requirements.txt` can never break a working ComfyUI.
# The few features that need those (SeedVR2, Flux PuLID) keep their own path.
