Printing model summary of python models built using Python Learner .

Rahul_M

Hi All, I have stored models which were built using Custom Python Learner in RapidMiner ? Is there any way to print the model information using these stored objects (.ioo) alone? I tried passing the Python model object as input to Execute Python and Python Transformer, but it failed to accept the input.

Hi @Rahul_M,

I've attached a small example, showing how you can use Execute Python to print the parameters to the log panel. The only challenge you may face is the exact code required will vary depending on the model type. I'd trained a simple sklearn model which I've also attached.

Hope this helps,

Best,

Roland
