ComfyUI Node
CV Build Information
Reports how THIS OpenCV was compiled - the answer to 'does my build have Eigen / non-free / OpenCL / CUDA', and the text to paste into a bug report. It replaces the raw cv2.getBuildInformation wrapper, which is deliberately not exposed: the banner is frozen at compile time and quotes the BUILD MACHINE's directories, so on a self-built OpenCV it carries your home directory, user name and project layout. This node redacts every path and reports how many it hid. Wire 'info' into core 'Preview as Text' to read it.

Inputs (1)
| Name | Type | Default | Description |
|---|---|---|---|
| redaction | COMBO | How much of each path to remove. Keeping the file name leaves the banner informative (which compiler, which python, which libraries - only WHERE they live is gone); hiding paths entirely replaces each one with '<path>'. Nothing else in the text is touched. |
Outputs (3)
| Name | Type | Description |
|---|---|---|
| info | STRING | The build banner with paths redacted. Multi-line; read it with core 'Preview as Text'. |
| has_eigen | BOOLEAN | True when the build reports 'Eigen: YES'. The Eigen-gated nodes (BIMEF, BIMEF2, ximgproc.fastBilateralSolverFilter) raise OpenCV error (-213) on every call when this is false - gate that branch with 'if/else'. |
| has_nonfree | BOOLEAN | True when the build reports 'Non-free algorithms: YES'. The pack never exposes a non-free function (they are blacklisted at generation time), so this is informational. |
