Evidence claims

[upstream_claim] README: V8.0 and later no longer install Impact-Subpack (needed for UltralyticsDetectorProvider) automatically; Python requirements include segment-anything, scikit-image, piexif, opencv-python, scipy, numpy<2, dill, matplotlib; V8.24 requires ComfyUI 0.3.63 or higher. source
[upstream_claim] Since V7.6 automatic dependency installation is no longer supported; manual installs run pip install -r requirements.txt in ComfyUI's own Python environment (python_embeded for Windows portable); install downloads sam_vit_b_01ec64.pth unless an empty skip_download_model file exists in custom_nodes. source
[upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

How should conflicting node-pack Python pins (torch, numpy, onnxruntime) be isolated in a single ComfyUI install? discusses → this
