Unfortunately, the steps provided to address this issue are not very helpful. They seem to assume a lot of things. For example, how does anyone who is using RapidMiner for the first time to get a feel of it, know how to generate an XML file for the process?
Besides, there are several other issues I am noticing right now with the overall UI itself. I am unable to find the "Data" option which I saw right after installation which I could use to play with IRIS data. I have restarted RapidMiner so many times after that and was never to get that option again.
I read the reviews about RapidMiner and they all seem to be speaking very high of it. I was very hopeful to see a good and intuitive tool when I read those reviews. But I am not really pleased with what I have seen so far. Maybe, it might be something at my end, but looks like a lot needs to be done, especially testing of the tool, at the RapidMiner end as well.
Hope someone will take notice of this feedback.

After some failed attempts, I finally got make it work. I think the tool has a lot of potential and I want to tell the product team that they really seem to have done a good job. However, the UI interface needs to be more intuitive and effective. For a first timer (who could be just a beginner or an experienced data scientist who might be evaluating it for some serious work for his/her organization), the very first experience is not without disappointment even when trying simple things. For example, I wanted to simply try running a decision tree with the IRIS dataset but getting it work really proved to be quite a challenge. I wanted to compare the output of the decision tree predictions of RapidMiner with the model I prepared using Scikit-learn in Python and see how close the two were.
Anyway, now that I made it work, I will continue exploring it more and probably some of the early frustrating experience I had with it will probably be compensated with some cool features it has to offer.
One thing I would add is the You Tube videos they provided are really of big help. I suggest they should add more such videos to help generate the knowledge about the tool.
How did you make it work? I got make it work, removing input conection to read csv operator.
Thx!
