Running python in Rapid Miner

Robi_MeRobi_Me Member Posts: 32 Maven
There is something that is not clicking with my understanding and I hope you can help. I am fully able to run the code inside of Google Colab and directly inside of Python, however I can never get my code to work in Rapid Miner. There is something I am just not getting. Why is it saying to me that "rm_main(data):" is missing when it is clearly in the script? 

What function does rm_main(data): fulfil and why must it be there?

I have attached a sample of my code, please explain where I am going wrong and what I am not understanding.

Thank you!

Shanti is a very friendly, cooperative, technical, and a hardworking individual. She is a team player who listens very carefully to the team\'s objectives and leads the team from the front. What I loved about working with Shanti was her ability to analyse a task in hand, do research about the unknowns in a collaborative manner and present it back. Although I worked in Cape Town, she worked from Italy, the distance was never an issue. She has the technology, communication skills and the right approach to work with the team remotely and face-to-face.

Hardworking, thorough, pro-active and team player are the words that come to my mind when I think about Carolyn. Her approach towards understanding the domain, software and the business makes it fun to work with her. She has excellent writing abilities, her verbal communication skills are no less. It is always a pleasure to be in her company because she continuously polishes her skills by studying more about her field of interest i.e. writing and reading.

She indeed is a senior team player who doesn\'t only want to documentation work get done, but also the software to get better from the end-user point of view. She quickly becomes indispensable to a team and I would love to be part of a team where she is the technical writer. Jackie is a person of many qualities.

As a tester, Ryan works hard on the tasks in hand, he is not shy to ask questions and help improving the product. The best thing I like about Ryan is his ever smiling face, he is very cooperative, he is a people\'s person and very well known figure in our company. I will not hesitate Ryan to any company who is looking for a hardworking tester or even an analyst Cooperation, collaboration, friendliness and patience are among many qualities Shahan possess. I found Shahan to be a professional who always focused towards customer and quality. He was patient towards customer queries and expert in handling critical situations.

    Hi @Robi_Me in the rm_main(data)  the function is expecting you to deliver a DataSet to the example set port of the python operator. If you are not delivering data to this operator you only need to declare the function in the following way.
