The Deeplearning4J example 04_Network_Example_Of_A_MLP_For_Images is not working. The DL4J Feedforward Learner (Classification) node does not recognize the "Image" column in the Column Selection tab. The KNIME Console prints out the warning:

you've to install the DeepLearning4J Image Processing extension (see https://tech.knime.org/deeplearning4j-imageprocessing). It's part of the KNIME Community Contributions (stable).
This is unfortunately a problem of the DL4J version we use in 3.5.x Do you use 3.6.x? Can you try to uninstall MKL which came with your anaconda installation? See also Knime 3.5.x Crash with DL4J integration - #2 by DaveK
