Cannot run Jupyter Notebook

Hi, I am very new to Rapidmider. I am trying to run a Jupyter notebook, but I keep getting this error: The execution of the Python script failed. Please check your Python script: TypeError: rm_main() missing 1 required positional argument.
I trying to run this code, because I saw in a video that I should write this command in order to start:

def rm_main(data):

print("hello")

return data
Thank you in advance!

Dear Karol,

The problem is probably, that you did not connected any data to the inp input port of the Execute Python operator, while you have defined 1 argument for rm_main. See the difference here:
