Hello,

The deep learning extension in rapidminer cannot predict label when a single sample is provided as a test file, it looks like the apply model in case of Deep learning extension needs a minimum of 2 samples. This looks like a bug.

I attached the .rmp file for process that throws a bug in this post. Below are the images related to this issue I cross-checked with @lionelderkrikor. It is evident that keras in python is able to predict on a single sample based on below images. @lionelderkrikor also tried the keras extension in rapidminer and observed that it cannot make a prediction on a single sample as well as shown below.

Thanks for looking into this. @ssv112 here is the issue we faced when we worked on your question.

@pschlunder can you please look into this.

Thanks
