Keras Error

I keep receiving these kinds of errors when trying to execute the 07_Sentiment_Analysis_with_Deep_Learning and 08_Sentiment_Analysis_with_Deep_Learning_KNIME_nodes example workflows. Anyone have an idea what they mean?

ERROR DL Python Network Creator 0:184 Execute failed: org.knime.python2.kernel.FlowVariableOptions.parse(Ljava/util/Map;)Lorg/knime/python2/kernel/FlowVariableOptions;

Execute failed: org.knime.python2.kernel.PythonKernel.getData(Ljava/lang/String;Lorg/knime/python2/extensions/serializationlibrary/interfaces/TableCreatorFactory;)Lorg/knime/python2/extensions/serializationlibrary/interfaces/TableCreator;

Hi nwoods,

This looks like a problem with your KNIME installation. Could you please try to reinstall the KNIME Keras integration (and – before – the KNIME Python integration, if installed)? You can uninstall an extension by selecting it under Help > About KNIME Analytics Platform >Installation Details > Installed Software and clicking Uninstall….

Additionally, could you upload your knime.log file here? (See here to learn how to locate the knime.log file.)
