Can't install KNIME AI Extension

[eddy0620]

Hi,Knimer
When re-install knime 5.4.3, the local GPT4ALL node was missing.
After uninstall KNIME AI Extension, then re-install AI Extension again. It still can’t solve this issue.
How to fix it?

Cannot complete the request.  See the error log for details.
"KNIME AI Extension" will be ignored because it is already installed.```

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?

Yes, I used MacOS 15.4 now.

Known macOS 15.4 Issue with KNIME’s Bundled Python Environments

Dear KNIME Community, We want to inform you of a known issue affecting the bundled Python environments in KNIME Analytics Platform on macOS 15.4. Root Cause Some Conda libraries—particularly libgfortran (used by numpy)—contain duplicate RPATH entries, causing them to fail to load on macOS 15.4. This is not limited to KNIME; it stems from a known problem in the numpy conda-forge feedstock (https://github.com/conda-forge/numpy-feedstock/issues/347), and a permanent fix is not yet available. In…

But this is specific to Python and I have several issues with that as well but in terms of using Knime and some of its extensions like the Knime Labs which has GPT4All etc. are not even showing up. When I try to install something like that it says they are already installed but I can’t find them. Could somebody please help?
