Hi @eddy0620,
If you are on macOS 15.4 you are maybe affected by Known macOS 15.4 Issue with KNIME’s Bundled Python Environments.
In any case, there should be a log entry starting with “Failed to parse Python node extension” in your KNIME Log (Menu → Show KNIME Log in File Explorer → knime.log) with details about why the extension could not be loaded. Could you post the details here?
