Load error on loading Guided Automation workflow in KNIME Web portal

#1

Hi, I am using the KNIME Server small 4.9.2 ami in AWS to use the Server functionality. After deploying the Guided Automation workflow available in KNIME Hub, when I try to load the workflow in webportal, I get the following error:

Errors loading workflow 01_Guided_Analytics_for_ML_Automation due to missing extensions.
Extensions: KNIME Core
Nodes: Table row to variable, Table row to variable
Extensions: KNIME Machine Learning Interpretability Extension
Node: Binary Classification Inspector

Can you please advise how I can fix this problem?

Thanks.

Hi @ramachna,

Seems like this workflow was created with the most recent version of KNIME Analytics Platform (4.1.0), while your server’s executor is 4.0.2. E.g., this Binary Classification Inspector node is a new node only available in 4.1.0.

If you want to use this workflow, you’ll need to upgrade your current machine to use KNIME Server 4.10 / Analytics Platform 4.1.0.

Cheers,
Roland

Thanks @RolandBurger. Can you please point me to where I can find the instructions for upgrading my AWS AMI from 4.9.2 to 4.10? I am using the AMI from AWS market place and I am on a “pay-as-you-go” model.
Thanks.

You can find update instructions here: https://docs.knime.com/2019-12/server_update_guide/index.html, that guide applies to AWS installations as well.

Note that this is a .0 release. For production environments, we recommend to wait for the release of KNIME Server 4.10.1, which is scheduled for the first week of February.

Cheers,
Roland
