I downloaded Roberto Cadili’s workflow “All Cats & Dogs? Classify Images with Codeless CNNs” at All Cats & Dogs? Classify Images with Codeless CNNs | KNIME. I ran it exactly as it was downloaded, of course adding the images to the folder where it was looking for them.
All the nodes in Step 1 Define Network Architecture have green dots and seem to have worked fine. Similarly, all the nodes in Step 2 Read and Preprocess Images have green dots and seem to have worked fine, as does the Conda Environment propagation.
But the processing stops at the Keras Network Learner. I get this error:
“Invalid settings: Selected input columns do not provide enough elements (1) to populate all neurons (67500) of network input ‘input_1_0:0’. Try adding some columns to the selection.”
Can someone provide suggestions as to what I should be doing at this point? Thank you!
