    02.01. Go to MenuPath: File\Install Knime Extensions
    02.02. Select Knime Labs Extension

Hey @betoespejop

Unfortunately the KNIME AI Extension was not available for v4.6, and can’t be installed into prior versions to my knowledge.


As @iCFO outlined,

the KNIME AI extension exists only since KAP version 5.1, see

Best regards


Hi guys.

I just checked my version KAP, and i have been using KNIME 5.1.1, However, it still doesn’t allow me to download AI Extension, I still have the same problem.


Try downloading other extensions and they work correctly, check the path length, the proxy, among other things.

maybe there is a way to download the AI ​​Extension, outside of the tool?

I appreciate if you have another idea to try.
Best regards

@betoespejop if you are behind a proxy you might want to check this thread:

There is a ticket to address this (AP-20960)


Thanks for updating! This is a different issue now.
On your 5.1 installation, could you try to obtain error logs as described in this post and also see whether the knime log has some more insights?

Hi @steffen_KNIME

I attach the log of the error that I get when I try to download the AI ​​extension.

I appreciate if you can help me with a solution.

can you please obtain the error logs as described in the first link of my previous post?


Hello Steffen, I am attaching the error log when trying to install the AI ​​extension.

Thank you for helping me solve this issue.

I don’t see much here and you also did not send the create_env.err file, but the create_env.out, is that correct? Is there none?
The interesting part might be

warning  libmamba Extracted package cache 'G:\KNIME\bundling\root\pkgs\llvm-meta-5.0.0-0' has invalid url

And I assume that is an proxy issue. As @mlauber71 pointed out, a solution will be implemented with AP-20960. The ticket has been resolved already and will be rolled out with the next release (5.2.0), probably in December.
