Printing model summary of python models built using Python Learner .
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.

Can I use the XML text of Rapidminer to open the process on another computer?
Hello. I have a question. When a process is run in RM, it generates an XML. I wonder if we can copy that XML, save it, and share it with another colleague so they can know which operators (and the whole process itself) were used. I have an older version of RM (5.3.015) so this method didn't work for me…

Storing and retrieving a model - Sentiment Analysis
Hi. I'm using the RapidMiner Sentiment Analysis template to start. After step 2, the Cross Validation operator, I thought why not just use the Store operator and pipe the model output to it? Seemed to work. The Store output matches the model output from the Cross Validation. Next, I deleted the operators from step 1 and…

Please HELP: how to use a CSV table of Tweets instead of document for sentiment analysis
So, I checked the sentiment analysis example. To predict sentiment, it takes on only a document. What if I have a CSV table with the Twitter user as a column, and the tweet text as another column. I want to run the prediction model on all of them, and get sentiment for each user (and his tweet)? When I try to do that, and…
