I came across a puzzling issue, I have a functional workflow using the keras network learner node for image-classification similar to the example workflow with cats and dogs.
However, on another machine, with the same data, workflow, and as far as I know same configuration, the keras network learner node does not see the image column !
The configuration window only shows the option for integer or double.
I’m quite sure I had the same issue with the Cats and dogs example, so I don’t think that it’s an issue with the workflow or data (224x224x3, FloatType images).
Where it works
On the other machine
Both configurations run
- Knime 4.1.3
and the CPU Deep learning environment as created by the KNIME Deep Learning preferences
(Python 3.6.10, TF 1.12.0 and Keras 2.2.4)
