Research direction
The failure is the import at line 7 of pyramid_blending.py, which pulls pad from kornia.geometry.transform.pyramid, reached through __init__.py line 49. Start by checking which kornia version is installed in the embedded Python environment and whether that module still exposes pad. Done means the node pack loads on a Windows portable install, most likely by fixing the import or pinning a compatible kornia version. The thread has 21 comments and no decision, so confirm the direction with maintainers first.
