HI, I have KNIME 3.5.1. I have installed Erlwood node and I used its, but from 2/3 weeks the node disappear from the repository. when I lunch a workflow with for example the 2d/3d scatterplot node I this message:
"2018-01-31 09:39:43,928 : ERROR : ModalContext : LoadWorkflowRunnable : : : Status: Error: Node "2D/3D Scatterplot" not available from extension "Erlwood Knime Open Source Core" (provided by "Erlwood"; plugin "org.erlwood.knime.core" is not installed)"
If I try to install it the programs say that it is already installed.
I also see this messages in KNIME console:
"ERROR RepositoryManager Node node.EvolutionaryAlgorithmNodeFactory' from plugin 'node' could not be created: Can't load factory class for node: node.EvolutionaryAlgorithmNodeFactory The corresponding plugin bundle could not be activated!
ERROR LoadWorkflowRunnable Errors during load: Status: Error: repro5 beta 0 loaded with errors
ERROR LoadWorkflowRunnable Status: Error: repro5 beta 0
ERROR LoadWorkflowRunnable Status: Error: Node "2D/3D Scatterplot" not available from extension "Erlwood Knime Open Source Core" (provided by "Erlwood"; plugin "org.erlwood.knime.core" is not installed)"
I try to unistall and install erlwood node but nothing change.
In case this helps. I imported a workflow using the pareto ranking onto a new computer. My Knime v3.5.1 detected that the node was missing and suggested I installed the “Erlwood Knime Open Source Core” extension. Turned out I had to install the “Erlwood Knime Open Source Cheminformatics” before that node worked for me.
I’m having similar problems with trying to run a workflow that contains the Erlwood 2D/3D node. Getting exactly the same error message as above. I tried to uninstall and then reinstall the Erlwood extensions. I also tried to uninstall and the most recently installed extensions (which were the 3D-e-Chem KNIME nodes). Neither of these attempts worked. I’m running on KNIME AP version 3.5.3. Was a definitive cause and solution for the above issue identified? If so could you please share? Any help would be much appreciated
Thanks in advance,
Mike
we tried to install an uninstall the questionable extensions (Cresset, Erlwood, 3D-e-Chem, NodePit) in quite some different orders, but could not reproduce the issue yet, i’m afraid.
From @michazeidan’s logs it follows that a class org.erlwood.knime.nodes.graph.NGraphNodeFactory can not be found. I suspect that this gets somehow lost in the course of installing new software (even though that’s strange).
KNIME/Eclipse has a plugin installation history. It should be stored in a folder like C:\Program Files\KNIME\p2\org.eclipse.equinox.p2.engine\profileRegistry\KNIMEProfile.profile\, where the C:\Program Files\KNIME\ part is the directory where you installed KNIME to. Could you zip that folder and attach it, please? With that, I could try and install the extensions in the same order you did and hopefully find some clues.
