I have installed the “KNIME AI Extension,” but I cannot see or use the nodes. The extension installation tool indicates that it is already installed.
To troubleshoot, I have reinstalled KNIME entirely, testing both the portable version and the system-installed version (with administrator privileges), but the issue persists.
nodes from other manually/additionally installed extensions are visible? What KNIME version and OS are you using? Installation process goes as expected - no warning/error messages?
Back in days there was -clean parameter when starting KNIME. Think the backend is same/similar so might help.
I think you can ignore above answer. I have found this from extension documentation: “For detailed solutions to common installation issues, please visit the “Installation Troubleshooting” chapter of the documentation (Create a New Python based KNIME Extension).”
