Errors in Keras Network Learner

[wisnupo]

when I use Keras network learner to create an image classification task, on the Keras network learner node an error appears like this:

“Error loading flow variables into node: The training data converter ‘org.knime.ip.dl.DLImgPlusValueToFloatTensorConverterFactory’ from network input ‘input_1_0:0’ could not be found. Are you missing the KNIME extension?”

how to solve this error?

Hi @wisnupo,

Could you check if the Keras and TensorFlow Libraries are setup properly in the python environment you are using? Share a screenshot similar to the below image.

Here is an article from @mlauber71 on Setting up Deep Learning Environments for Keras and TensorFlow in KNIME. I found a similar issue being discussed on the forum here. Hope this helps.

Best,
