Hi,
I am trying to run the workflow published recently in the KNIME Blog (Using DeepLearning4J to classify MNIST digits). After struggling a bit with the Python installation (Protobuf a.o.), I have now the following issue:
The DL4J FeedForward Learner node (Classification) does not seem to recognize/accept a picture column as Feature Column. In the Column Selection Tab, both sides for manual selection are empty, although the pictures are available in the input (and can be visualized in the Image Viewer node).
Am I doing something wrong here?
I'm using KNIME 3.4 with all nodes up-to-date.
Thanks for your help
